The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.

[0003] The invention relates generally to computer network data access, and more particularly to systems, methods and data structures for accessing data and data-related services over a network.

[0004] There are many types of data that users need to manage and otherwise access. For example, users keep word processing documents, spreadsheet documents, calendars, telephone numbers and addresses, e-mail messages, financial information and so on. In general, users maintain this information on various personal computers, hand-held computers, pocket-sized computers, personal digital assistants, mobile phones and other electronic devices. In most cases, a user's data on one device is not accessible to another device, without some manual synchronization process or the like to exchange the data, which is cumbersome. Moreover, some devices do not readily allow for synchronization. For example, if a user leaves his cell phone at work, he has no way to get his stored phone numbers off the cell phone when at home, even if the user has a computing device or similar cell phone at his disposal. As is evident, these drawbacks result from the separate devices each containing their own data.

[0005] Corporate networks and the like can provide users with remote access to some of their data, but many users do not have access to such a network. For many of those that have access, connecting to a network with the many different types of devices, assuming such devices can even connect to a network, can be a complex or overwhelming problem.

[0006] Moreover, even if a user has centrally stored data, the user needs the correct type of device running the appropriate application program to access that data. For example, a user with a PDA that runs a simple note taking application program ordinarily will not be able to use that program to open documents stored by a full-blown word processing program at work. In general, this is because the data is formatted and accessed according to the way the application program wants it to be formatted.

[0007] What is needed is a model wherein data is centrally stored for users, with a set of services that control access to the data with defined methods, regardless of the application program and/or device. When accessed, the data for each service should be structured in a defined way that complies with defined rules for that data, regardless of the application program or device that is accessing the data.

[0008] Briefly, the present invention provides a set of services for central (e.g., Internet) access to per-user data, based on each user's identity, wherein each service includes a schema that defines rules and a structure for the data, and also includes methods that provide access to the data in a defined way. Note that while “user” is generally employed herein for simplicity, as used herein the term “user” is really a substitute for any identity, which may be a user, a group, another entity, an event, a project, and so on. Because the structure of the data is defined from the perspective of the data, not from that of an application program or a device, programs can communicate with the services to access the data, with existing knowledge of the format. In one implementation, the schemas are arranged as XML documents, and the services provide methods that control access to the data based on the requesting user's identification, defined role and scope for that role. In this way, data can be accessed by its owner, and shared to an extent determined by the owner. Extensibility is defined into the schemas.

[0009] In one implementation, core services are provided for managing access of various types of data, each service corresponding to a defined schema for the type of data it manages. In addition to defined schemas for the data, the various services implement standard methods that application programs can call in order to obtain access to the data, and also may include custom methods that facilitate access, referred to as domain-specific methods. Core services include myServices, to allow applications to find another service, myApplicationSettings, to allow a user to centrally store settings for the user's various applications, and myCalendar, which manages access to data regarding scheduled events. Other core services include myCategories, to provide a generic classification model, myContacts, to manage access to a user's list of contacts, and myDevices, to manage a user's devices. Other, core services include myDocuments, myFavoriteWebSites, myInbox, myLists, myLocation, myAlerts, myProfile, myPresence and myWallet, as described below. Note that each of these services are alternatively and interchangably referred to herein by “.NET” followed by their name, e.g., myInbox may be referred to as .NET Inbox, or simply Inbox, myContacts as .NET Contacts, or simply Contacts, and so on. Note that this is only one exemplary set of core services, and that other core services implementations may include a different combination of these services (i.e. a subset) and/or additional services which may be considered as “core” services.

[0010] Extended (or optional) services are also allowed. The extended services need not be provided by the provider of the core services, e.g., there may be a number of users who subscribe to one companies core services but only subscribe to third party extended services. Likewise, there may be a number of services providers who provide core services or extended services but not both. Thus, it should be understood that a core services provider may also provides extended services, or providers of core or extended services, or both, may be different entities.

[0011] Other benefits and advantages will become apparent from the following detailed description when taken in conjunction with the drawings, in which:

Exemplary Operating Environment

[0023] FIG. 1 illustrates an example of a suitable computing system environment 100 on which the invention may be implemented. The computing system environment 100 is only one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention. Neither should the computing environment 100 be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in the exemplary operating environment 100.

[0024] The invention is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well known computing systems, environments, and/or configurations that may be suitable for use with the invention include, but are not limited to: personal computers, server computers, hand-held or laptop devices, tablet devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.

[0025] The invention may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, and so forth, that perform particular tasks or implement particular abstract data types. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in local and/or remote computer storage media including memory storage devices.

[0026] With reference to FIG. 1, an exemplary system for implementing the invention includes a general purpose computing device in the form of a computer 110. Components of the computer 110 may include, but are not limited to, a processing unit 120, a system memory 130, and a system bus 121 that couples various system components including the system memory to the processing unit 120. The system bus 121 may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus also known as Mezzanine bus.

[0027] The computer 110 typically includes a variety of computer-readable media. Computer-readable media can be any available media that can be accessed by the computer 110 and includes both volatile and nonvolatile media, and removable and non-removable media. By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can accessed by the computer 110. Communication media typically embodies computer-readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer-readable media.

[0028] The system memory 130 includes computer storage media in the form of volatile and/or nonvolatile memory such as read only memory (ROM) 131 and random access memory (RAM) 132. A basic input/output system 133 (BIOS), containing the basic routines that help to transfer information between elements within computer 110, such as during start-up, is typically stored in ROM 131. RAM 132 typically contains data and/or program modules that are immediately accessible to and/or presently being operated on by processing unit 120. By way of example, and not limitation, FIG. 1 illustrates operating system 134, application programs 135, other program modules 136 and program data 137.

[0029] The computer 110 may also include other removable/non-removable, volatile/nonvolatile computer storage media. By way of example only, FIG. 1 illustrates a hard disk drive 141 that reads from or writes to non-removable, nonvolatile magnetic media, a magnetic disk drive 151 that reads from or writes to a removable, nonvolatile magnetic disk 152, and an optic al disk drive 155 that reads from or writes to a removable, nonvolatile optical disk 156 such as a CD ROM or other optical media. Other removable/non-removable, volatile/nonvolatile computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, digital versatile disks, digital video tape, solid state RAM, solid state ROM, and the like. The hard disk drive 141 is typically connected to the system bus 121 through a non-removable memory interface such as interface 140, and magnetic disk drive 151 and optical disk drive 155 are typically connected to the system bus 121 by a removable memory interface, such as interface 150.

[0030] The drives and their associated computer storage media, discussed above and illustrated in FIG. 1, provide storage of computer-readable instructions, data structures, program modules and other data for the computer 110. In FIG. 1, for example, hard disk drive 141 is illustrated as storing operating system 144, application programs 145, other program modules 146 and program data 147. Note that these components can either be the same as or different from operating system 134, application programs 135, other program modules 136, and program data 137. Operating system 144, application programs 145, other program modules 146, and program data 147 are given different numbers herein to illustrate that, at a minimum, they are different copies. A user may enter commands and information into the computer 20 through input devices such as a tablet, or electronic digitizer, 164, a microphone 163, a keyboard 162 and pointing device 161, commonly referred to as mouse, trackball or touch pad. Other input devices not shown in FIG. 1 may include a joystick, game pad, satellite dish, scanner, or the like. These and other input devices are often connected to the processing unit 120 through a user input interface 160 that is coupled to the system bus, but may be connected by other interface and bus structures, such as a parallel port, game port or a universal serial bus (USB). A monitor 191 or other type of display device is also connected to the system bus 121 via an interface, such as a video interface 190. The monitor 191 may also be integrated with a touch-screen panel or the like. Note that the monitor and/or touch screen panel can be physically coupled to a housing in which the computing device 110 is incorporated, such as in a tablet-type personal computer. In addition, computers such as the computing device 110 may also include other peripheral output devices such as speakers 195 and printer 196, which may be connected through an output peripheral interface 194 or the like.

[0031] The computer 110 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 180. The remote computer 180 may be a personal computer, a server, a router, a network PC, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computer 110, although only a memory storage device 181 has been illustrated in FIG. 1. The logical connections depicted in FIG. 1 include a local area network (LAN) 171 and a wide area network (WAN) 173, but may also include other networks. Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets and the Internet. For example, in the present invention, the computer system 110 may comprise source machine from which data is being migrated, and the remote computer 180 may comprise the destination machine. Note however that source and destination machines need not be connected by a network or any other means, but instead, data may be migrated via any media capable of being written by the source platform and read by the destination platform or platforms.

[0032] When used in a LAN networking environment, the computer 110 is connected to the LAN 171 through a network interface or adapter 170. When used in a WAN networking environment, the computer 110 typically includes a modem 172 or other means for establishing communications over the WAN 173, such as the Internet. The modem 172, which may be internal or external, may be connected to the system bus 121 via the user input interface 160 or other appropriate mechanism. In a networked environment, program modules depicted relative to the computer 110, or portions thereof, may be stored in the remote memory storage device. By way of example, and not limitation, FIG. 1 illustrates remote application programs 185 as residing on memory device 181. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.

Data Access Model

[0033] The present invention generally operates in an architecture/platform that connects network-based (e.g., Internet-based) applications, devices and services, and transforms them into a user's personal network which works on the user's behalf, and with permissions granted by the user. To this end, the present invention is generally directed to schema-based services that maintain user, group, corporate or other entity data in a commonly accessible virtual location, such as the Internet. The present invention is intended to scale to millions of users, and be stored reliably, and thus it is likely that a user's data will be distributed among and/or replicated to numerous storage devices, such as controlled via a server federation. As such, while the present invention will be generally described with respect to an identity-centric model that enables a user with an appropriate identity and credentials to access data by communicating with various core or other services, it is understood that the schema-based services described herein are arranged for handling the data of millions of users, sorted on a per-user-identity basis. Note that while “user” is generally employed herein for simplicity, as used herein the term “user” is really a substitute for any identity, which may be a user, a group, another entity, an event, a project, and so on.

[0034] As generally represented in FIG. 2, a data access model 200 includes a generic navigation module 202 through which applications 204 and the like may access a wide variety of identity-based data, such as maintained in an addressable store 206. To access the data, a common set of command methods may be used to perform operations on various data structures that are constructed from the data in the addressable store 206, even though each of those data structures may represent different data and be organized quite differently. Such command methods may describe generic operations that may be desired on a wide variety of data structures, and include, for example, insert, delete, replace, update, query or changequery methods.

[0035] In accordance with one aspect of the present invention and as described in detail below, the data is accessed according to various schemas, with the schemas corresponding to identity-based services through which users access their data. As used herein, a “schema” generally comprises a set of rules that define how a data structure may be organized, e.g., what elements are supported, in what order they appear, how many times they appear, and so on. In addition, a schema may define, via color-coding or other identification mechanisms, what portions of an XML document (that corresponds to the data structure) may be operated on. Examples of such XML-based documents are described below. The schema may also define how the structure of the XML document may be extended to include elements not expressly mentioned in the schema.

[0036] As will be understood below, the schemas vary depending on the type of data they are intended to organize, e.g., an email-inbox-related schema organizes data differently from a schema that organizes a user's favorite websites. Further, the services that employ schemas may vary. As such, the generic navigation module 202 has associated therewith a navigation assistance module 208 that includes or is otherwise associated with one or more schemas 210. As will be understood, a navigation assistance module 208 as represented in FIG. 2 corresponds to one or more services, and possesses the information that defines how to navigate through the various data structures, and may also indicate which command methods may be executed on what portions of the data structure. Although in FIG. 2 only one navigation assistance module 208 is shown coupled to the generic navigation module 202, there may be multiple navigation assistance modules that may each specialize as desired. For example, each navigation assistance module may correspond to one service. Moreover, although the navigation assistance module 208 is illustrated as a separate module, some or all of the operations of the navigation assistance module 208 may be incorporated into the generic navigation module 202, and vice versa. In one embodiment, the various data structures constructed from the schema and addressable store data may comprise XML documents of various XML classes. In that case, the navigation assistance module 208 may contain a schema associated with each of the classes of XML documents.

[0037] The present invention provides a number of schema-based services that facilitate data access based on the identity of a user. Preferably, the user need not obtain a separate identity for each service, but rather obtains a single identity via a single set of credentials, such as with the Microsoft® Passport online service. With such an identity, a user can access data via these services from virtually any network connectable device capable of running an application that can call the methods of a service.

Services and Schemas

[0038] “.NET My Services” comprises identity-centric services which may be generally implemented in XML (eXtensible Markup Language) Message Interfaces (XMIs). While the present invention will be described with respect to XML and XMI, it can readily be appreciated that the present invention is not limited to any particular language or set of interfaces. The .NET My Services model essentially corresponds to one implementation of the generic data access model 200 of FIG. 2.

[0039] As generally represented in FIG. 3, .NET My Services 300 is implemented as a set of Web services 301-316, each bound to a .NET Identity (PUID, such as a Passport® unique identifier similar to a globally unique indentifier when Passport® is the authentication service). The services 301-316 can communicate with one another via a service-to-service communications protocol (SSCP), described below. As also described below, each service presents itself as a set of XML documents that can be manipulated from an application program 202 (FIG. 2) or the like using a set of standard methods and domain-specific methods. To this end, a user device 320 (endpoint) running such application programs connects a user's applications to the services, and the data controlled by those services, such as over the Internet or an Intranet, such as over the Internet or an Intranet. Note that endpoints can be client devices, applications or services. In keeping with the present invention, virtually any device capable of executing software and connecting to a network in any means may thus give a user access to data that the user is allowed to access, such as the user's own data, or data that a friend or colleague has specified as being accessible to that particular user.

[0040] In general, a .NET Identity is an identifier assigned to an individual, a group of individuals, or some form of organization or project. Using this identifier, services bound to that identity can be located and manipulated. A general effect is that each identity (e.g., of a user, group or organization) has tied to it a set of services that are partitioned along schema boundaries and across different identities. As will be understood, the XML-document-centric architecture of .NET My Services provides a model for manipulating and communicating service state that is very different from prior data access models. The XML-document-centric approach, in conjunction with loose binding to the data exposed by the services, enables new classes of application programs. As will also be understood, the .NET My Services model 300 presents the various services 301-316 using a uniform and consistent service and method model, a uniform and consistent data access and manipulation model, and a uniform and consistent security authorization model.

[0041] In a preferred implementation, the .NET My Services model 300 is based upon open Internet standards. Services are accessed by means of SOAP (Simple Object Access Protocol) messages containing an XML payload. Service input and output is expressed as XML document outlines, and each of these document outlines conform to an XML schema document. The content is available to a user interacting with the .NET My Services service endpoint 320.

[0042] One aspect of the present invention is that a schema essentially describes a web service. More particularly, a service author begins to write a web service by defining a schema (e.g., in XML) that defines what the data model looks like, e.g., the supported elements, their relative ordering, how many times they appear, and other similar definitions, as will become apparent below. This service definition also applies to an author determining what roles and methods are supported, e.g., which operations are supported, and the extent of the data that can be returned for each method. Another way of stating this concept is that the author starts by building a complete definition of a service, such as in XML, and specifies the verbs (methods) that an application will use to talk to it.

[0043] At this point, the service author has an XML definition that has been declared, and this declarative definition may be run through a compilation process, resulting in a fully operational service. It should be noted that a general purpose interpreter-like mechanism may be fed one of these declarative XML definitions, and result in a service that is capable of operating. In a simple service (e.g., with no domain-specific methods or complex logic), no new code needs to be written to provide such an operational service. As will be understood, such authoring of a service without coding is possible due to the data driven model of the present architecture. As will be understood, however, code can also be written to influence and or work with the service generation process to add value to a service, and/or provide specific, runtime business logic that is not expressible in a declarative way.

[0044] Turning to FIG. 4, in the .NET My Services model, an application 400 requests performance of a method that operates on data structures. The application may make a request that is generic with respect to the type of data structure being operated upon and without requiring dedicated executable code for manipulating data structures of any particular data type. To this end, the application first contacts a myServices service 314 (which may be referred to as .NET Service) to obtain the information needed to communicate with a particular service 404, through a set of methods 406 of that service 404. For example, the needed information received from the myServices service 314 includes a URI of that service 404. Note that the service 404 may correspond to essentially any of the services represented in FIG. 3. The myServices service 314 is further described below with respect to FIGS. 5A and 5B.

[0045] The service 404 includes or is otherwise associated with a set of methods 406 including standard methods 408, such as to handle requests directed to insert, delete, replace, update, query or changequery operations on the data. The set of methods of a particular service may also include service specific methods 410. In general, the only way in which an application can communicate with a service are via that service's methods.

[0046] Each service includes service logic 412 for handling requests and providing suitable responses. To this end, the service logic performs various functions such as authorization, authentication, and signature validation, and further limits valid users to only the data which they are permitted to access. The security aspect of a service is not discussed herein, except to note that in general, for otherwise valid users, the user's identity determines whether a user can access data in a requested manner. To this end, a roleMap 414 comprising service-wide roleList document templates 415 and scopes (e.g., part of the overall service's schema 416), in conjunction with user-based data maintained in an addressable store 418, determines whether a particular requested method is allowed, e.g., by forming an identity-based roleList document 420. If a method is allowed, the scope information in the roleMap 414 determines a shape of data to return, e.g., how much content is allowed to be accessed for this particular user for this particular request. The content is obtained in accordance with a content document 422 in the service's schema 416 and the actual user data corresponding to that content document in the addressable store 418. In this manner, a per-identity shaped content document 424 is essentially constructed for returning to the user, or for updating the addressable store, as appropriate for the method. Note that FIG. 4 includes a number of ID-based roleList documents and ID-based content documents, to emphasize that the service 406 is arranged to serve multiple users. Also, in FIG. 4, a system document 426 is present as part of the schema 416, as described below.

[0047] Returning to FIG. 3, in one implementation, access to .NET My Services 300 is accomplished using SOAP messages formatted with .NET My Services-specific header and body content. Each of the services will accept these messages by means of an HTTP POST operation, and generate a response by “piggy-backing” on the HTTP Response, or by issuing an HTTP POST to a .NET MyServices response-processing endpoint 320. In addition to HTTP as the message transfer protocol, .NET My Services will support raw SOAP over TCP, a transfer protocol known as Direct Internet Message Encapsulation (or DIME). Other protocols for transferring messages are feasible.

[0048] Because each of the .NET My Services services are accessed by protocol, no particular client-side binding code, object models, API layers, or equivalents are required, and are thus optional. The .NET My Services model will support Web Services Description Language (WSDL). It is not mandatory that applications wishing to interact with .NET My Services services make use of any particular bindings, and such bindings are not described herein. Instead, the present invention will be generally described in terms of messages that flow between requestors of a particular service and the service endpoints. In order to interact with .NET My Services, a service needs to format a .NET My Services message and deliver that message to a .NET My Services endpoint. In order to format a message, a client needs to manipulate XML document outlines, and typically perform some simple, known (public-domain) cryptographic operations on portions of the message.

[0049] In accordance with one aspect of the present invention, and as described in FIG. 4 and below, in one preferred implementation, each .NET My Services service presents three logical XML documents, a content document 422, roleList document 415 (of the roleMap 414), and a system document 426. These documents are addressable using .NET My Services message headers, and are manipulated using standard .NET My Services methods. In addition to these common methods, each service may include additional domain-specific methods. For example, as described below, the myCalendar service 303 might choose to expose a “getFreeBusy” method rather than expose free/busy as writeable fragments in the content document.

[0050] Each .NET My Services service thus logically includes a content document 422, which in general is the main, service-specific document. The schema for this document 422 is a function of the class of service, as will become apparent from the description of each service's schema below. For example, in the case of the myCalendar service 303, the content document presents data in the shape dictated by the myCalendar schema, whereas in the case of the myFavoriteWebSites service 308, the content document presents data in the shape dictated by a myFavoriteWebSites schema.

[0051] Each service also includes a roleList document 415 that contains roleList information, comprising information that governs access to the data and methods exported by the service 404. The roleList document is manipulated using the .NET standard data manipulation mechanisms. The shape of this document is governed by the .NET core schema's roleListType XML data type.

[0052] Each service also includes a system document 426, which contains service-specific system data such as the roleMap, schemaMap, messageMap, version information, and service specific global data. The document is manipulated using the standard .NET My Services data manipulation mechanism, although modifications are limited in a way that allows only the service itself to modify the document. The shape of this system document 426 may be governed by the system document schema for the particular service, in that each service may extend a base system document type with service specific information. For purposes of simplicity herein, the base system document is described once, rather than for each service, with only those services having extended service specific information separately described. Notwithstanding, it should be understood that each service includes at least the base system portion in its system document.

[0053] As is understood, the present invention is generally directed to schemas, which in general comprise a set of rules or standards that define how a particular type of data can be structured. Via the schemas, the meaning of data, rather than just the data itself, may be communicated between computer systems. For example, a computer device may recognize that a data structure that follows a particular address schema represents an address, enabling the computer to “understand” the component part of an address. The computer device may then perform intelligent actions based on the understanding that the data structure represents an address. Such actions may include, for example, the presentation of an action menu to the user that represents things to do with addresses. Schemas may be stored locally on a device and/or globally in a federation's “mega-store.” A device can keep a locally-stored schema updated by subscribing to an event notification service (in this case, a schema update service) that automatically passes messages to the device when the schema is updated. Access to globally stored schemas is controlled by the security infrastructure.

General Schema Commonality

[0054] The .NET My Services data is defined using annotated XSD (eXtensible or XML Structure Definitions) schema files. The XSD files accurately type the data, but since XSD is a verbose and complex language, it is not a particularly efficient way to convey structure and meaning. Thus, for purposes of simplicity herein, the schemas are described below in terms of schema outlines with accompanying element/attribute descriptions. These document outlines accurately show the structure of the data contained within a service. However, because the present application is not viewable in color, the nodes, elements and/or attributes of the schema outlines (which may be described as bold blue, or blue), are represented in the schema outlines as boldface type. Those described as underlined red, or red, are represented as underlined type, while others referred to as black are represented in normal type.

[0055] The meaning of these bold (blue), underlined (red) and normal (black) items has significance with respect to the data model and to the data language that accesses and manipulates the data (e.g., via the insert, delete, replace, update, query, changequery or other methods). For example, each document described below contains a root element having an element name that matches that of the service, e.g., the myApplicationsSettings service has a root element named myApplicationsSettings. The .NET My Services name for this item is the root.

[0056] Documents contain elements that resemble first-class top-level objects, including, for example, <catDef/>, <myApplicationsSettings/> (other another name as appropriate) and <order/>. Such items are denoted in the outlines as bold (blue), and may be identified using an <xdb:blue/> tag. Bold (blue) items define major blocks of data within a service. These node sets are directly addressable by an identifier attribute, and their change status is tracked through a changeNumber attribute. Top-level bold blue items may be considered objects. As seen below, some bold (blue) objects contain nested bold blue objects. They usually contain frequently changing underlined (red) properties, which reduces the amount of synchronization traffic. Nested bold (blue) items may be considered property groups.

[0057] Each bold blue item contains one or more underlined (red) items which are elements or attributes. These items may be identified using the <xdb:red/> tag. These items are special in that they may be used within predicates (filters) to aid in xdb:bold blue selection. These items are also directly addressable and may be manipulated directly by the data manipulation language.

[0058] Each colored red element may contain one or more non-colorized elements and attributes, which are valid and semantically meaningful XML items in the service document. Such items are opaque to the data language. These uncolored (i.e., non-bold or underlined) elements and attributes may not be addressed directly, may not be selected in a node selection operation, and may not be used in a predicate node test. Note that if one of these items is in the path to an underlined red item, it may be used in a location step to the underlined red item, but may not be used as the selected node. Note that being opaque does not mean that the item is not considered during schema validation, but rather means that the item may not be used in a predicate, may not be directly addressed, and may not be inserted by itself. As can be readily appreciated, in this manner, the .NET My Services thus limits the granularity of access to nodes within the service document, since only xdb:bold blue and xdb:underlined red marked items are directly addressable, and only those elements and attributes tagged with the xdb:underlined red annotation may be used in predicates to influence node selection. Using this technique, the .NET My Services storage system can efficiently manage indexes, increase the performance of node selection, partially shred the document data, and in general (because the node selections are well defined) fine-tune the node selection logic on a per-xdb:blue basis. The primary purpose of the xdb:blue is to define a base-level XML object that is designed to be operated on as a unit. The primary purpose of the xdb:red items is to aid in the selection of xdb:bold blues. The xdb:red items may be changed by the data language primitives so some level of fine-grained manipulation of the data is available, but only in very limited ways.

[0059] Bold blue items have unique IDs, which are usually assigned by .NET My Services, and are returned from update operations within the new blueId node. In all cases, the order of xxxBold blue follows the pre-order traversal of the document XML tree. Item IDs are UUIDs in the following format (h stands for a hexadecimal digit): hhhhhhhh-hhhh-hhhh-hhhh-hhhhhhhhhhhh.

[0060] In addition to identifiers, names and change numbers, nodes and especially red nodes may include creator identifiers, category information, and {any} fields. Category information enables data to be grouped and/or distinguished in some way, such as to share certain calendar information with golf buddies, send an email to immediately family, designate things such as which telephone number is the user's primary number, e.g., if a user has a second home, and so on. Fields of type “any” may comprise fully-typed, namespace-qualified fields that contain any type of content (e.g., free-form XML) therein. Such “any” fields thus allow extensibility of the schema, yet maintain the defined structure of a schema.

[0061] In one implementation, the core data-manipulation language implemented by the .NET My Services includes an insertRequest, or insert message. This primitive inserts any schema-valid XML fragment into a selected context, thereby changing the existing state of the document. A queryRequest, or message, retrieves data, such as to retrieve a document. Multiple queries may be specified in one request, and queries that select nothing are considered successful. It is possible to assert that the number of nodes in the selection falls in a given range. This is expressed using minOccurs and maxOccurs attributes. If a minOccurs/maxOccurs test fails on any node, the request is considered unsuccessful. Note that this is different from a failure code, which would be returned, for example, for a malformed request.

[0062] A deleteRequest primitive deletes the selected nodes and all their children. Note that, just like for other requests, attributes may be selected as well as elements. Empty selections result in successful operations, similar to Query. The minOccurs/maxOccurs tests are supported wherever select is allowed.

[0063] A replaceRequest primitive (replace message) is designed to replace the content of each of the selected nodes with the specified new content. Selected nodes themselves are not affected in any way. This may be considered as an atomic delete of the content of the selected node, followed by an insert. The content (text, attributes, elements) in the selected nodes are replaced with the new item specified in this message. The node type of the selected node and of the replacement node are thus required to be the same. The changequery request essentially returns result comrpising data that has changed.

[0064] As mentioned above, each of the services includes a RoleList document and scope information that describes which users have what type of access to which data. For example, a data owner will have read/write access to his or her own data, and can provide various types of rights to that data to other users based on their IDs, (e.g., read only to some users, read write to others). Each role list identifier may be associated with a scope, by which the kinds of data stored according to a given schema can be controlled per user. For example, a user can give a friend (with one identity) access via a service to a home telephone number, home address and so forth, but can give other users (with other identities) access only to a business telephone number. In general, a scope can be defined such that that it includes everything except any specifically listed items, or excludes everything except any specifically listed items.

Base System Document Items

[0065] The system document is a global document for each service, having content and meaning that is independent of the puid used to address the service. The document is read only to all users. Each system document contains a set of base items common to each .NET My Services service described herein, and is optionally extended by each service to include service-specific global information. Throughout the following examples, an “hs” as in <hs: scope . . . > represents the namespace or schematic that may be used to interpret the corresponding element. For purposes of avoiding repetition, any extended system information is separately described with respect to each service, and the following schema outline illustrates the layout and meaning of the information found in the base system document that is common among the services:

[0066]

[0067] The meaning of the attributes and elements shown in the preceding sample document outline follow, beginning with /system (minOccurs=1 maxOccurs=1), the element that encapsulates a system document common to the various services. Although each service has its own system document, the common system document attributes and elements are described once, for purposes of simplicity, with service-specific system document attributes and elements specified for each service, below. The /system/@changeNumber (minOccurs=0 maxOccurs=1) attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0068] The /system/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a user is provisioned for a particular service.

[0069] The /system/systemVersion (minOccurs=1 maxOccurs=1) element defines version information describing this instance of the .NET My Services service. The /systemVersion/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications; attempts to write this attribute are silently ignored, (e.g., without generating an error).

[0070] The /system/systemVersion/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0071] The /system/systemVersion/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /system/systemVersion/version (minOccurs=1 maxOccurs=1) element defines major, minor, and build number version information. The /system/systemVersion/version/@majorVersion (string minOccurs=0 maxOccurs=1) attribute specifies the major version number of the .NET My Services Service.

[0072] The /system/systemVersion/version/@minorVersion (string minOccurs=0 maxOccurs=1) attribute specifies the minor version number of the .NET MyServices service. The /system/systemVersion/version/@buildNumber (string minOccurs=0 maxOccurs=1) attribute specifies the buildNumber of the .NET MyServices service. The /system/systemVersion/version/@qfe (string minOccurs=0 maxOccurs=1) attribute specifies the qfe version number of the .NET MyServices service. The /system/systemVersion/version/productReleaseName (string minOccurs=1 maxOccurs=1) element defines the major product release string (as in .NET My Services Beta 1, and so on). The /system/systemVersion/version/productImplementationName (anyURI minOccurs=1 maxOccurs=1) element defines the class of the service to differentiate between different implementations.

[0073] The /system/systemVersion/buildDate (dateTime minOccurs=1 maxOccurs=1) element defines the date and time that the .NET My Services system was built. The time is in UTC (Z relative) form. The /systemVersion/buildDetails (minOccurs=1 maxOccurs=1) element defines details of the build including the machine that generated the build, the branch id of the software that contributed to the build, the type of build (chk/fre), and if the build was generated by an official build release process.

[0074] The /system/systemVersion/buildDetails/@machine (string minOccurs=0 maxOccurs=1) attribute specifies the machine that generated the build. The system/systemVersion/buildDetails/@branch (string minOccurs=0 maxOccurs=1) attribute specifies the software branch id for the source code that contributed to this build. The /system/systemVersion/buildDetails/@type (string minOccurs=0 maxOccurs=1) attribute specifies the type of build. A value of chk indicates that this is a checked or debug build. A value of fre indicates that this is a retail build. The /system/systemVersion/buildDetails/@official (string minOccurs=0 maxOccurs=1) attribute indicates that the build was produced by an official build process (value of yes), or an unofficial process (value of no).

[0075] The /system/roleMap (minOccurs=1 maxOccurs=1) element encapsulates all the elements that make up a roleMap, which include document class relative roleTemplate, priority, name, method, and per-method scope. An individual roleTemplate defines the maximum scope of information, and the allowable methods used to access that information for each request mapped into the template. The /system/roleMap/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored. The /system/roleMap/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0076] The /system/roleMap/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /system/roleMap/scope (minOccurs=0 maxOccurs=unbounded) element defines a scope which may be referred to by roles within this roleMap to indicate what portions of the document are visible to this role for the specified method.

[0077] The /system/roleMap/scope/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored. The /system/roleMap/scope/name (string minOccurs=0 maxOccurs=unbounded) node includes the /system/roleMap/scope/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute, which is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766 (wherein ISO stands for International Organization for Standardization and RFC stands for Request For Comment). The value of this attribute indicates the language type of the content within this element. The /system/roleMap/scope/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left), and ltr (left to right).

[0078] The /system/roleMap/scope/shape (minOccurs=1 maxOccurs=1) comprises a shape that defines the node set that is visible through the document when operating through this shape element. The /system/roleMap/scope/shape/@base (string minOccurs=0 maxOccurs=1) attribute specifies the initial set of nodes visible through the shape. A value of t indicates that the shape is initialized to include all possible nodes relative to the shape that is currently in effect. For instance, each role defines a scope containing a shape. When defining a shape for a role, the value t indicates all possible nodes available in the specified document for this role. When defining a shape in an ACL entry, a value of t means all of the nodes visible in the shape for the computed role. When using a shape in a data language (e.g., query, insert, replace and so on) operation, a value of t indicates all of the possible nodes selected by the data language operation (relative to the ACL shape which itself is relative to the role's shape). The value nil indicates the opposite of t, which is the empty node set. Nodes from this set may then be included into the shape.

[0079] The /system/roleMap/scope/shape/include (minOccurs=0 maxOccurs=unbounded) element specifies the set of nodes that should be included into the shape relative to the possible set of nodes indicated by the base attribute. The /system/roleMap/scope/shape/include/@select (string minOccurs=0 maxOccurs=1) item specifies an XPATH expression that selects a set of nodes relative to the externally established context. The expression can never travel outside the node-set established by this externally established current context. The expression may match zero or more nodes, and the operation manipulates all selected nodes. The minOccurs and maxOccurs attributes are optional and place restrictions and limitations on the number of nodes selected.

[0080] The /system/roleMap/scope/shape/exclude (minOccurs=0 maxOccurs=unbounded) element specifies the set of nodes that should be excluded from the shape relative to the possible set of nodes indicated by the base attribute. The /system/roleMap/scope/shape/exclude/@select (string minOccurs=0 maxOccurs=1) item specifies an XPATH expression that selects a set of nodes relative to the externally established context. The expression can never travel outside the node-set established by this externally established current context. The expression may match zero (0) or more nodes, and the operation manipulates all selected nodes. The minOccurs and maxOccurs attributes are optional and place restrictions and limitations on the number of nodes selected. The /system/roleMap/roleTemplate (minOccurs=0 maxOccurs=unbounded) element encapsulates the definition of a role. The attribute set for this element includes the document class that this roleTemplate refers to, the name of the roleTemplate, and the priority of the roleTemplate.

[0081] The /system/roleMap/roleTemplate/@name (string minOccurs=0 maxOccurs=1) element specifies the name of the role. The /system/roleMap/roleTemplate/@priority (int minOccurs=0 maxOccurs=1) element specifies the priority of the roleTemplate which is used to select that actual roleTemplate when the role evaluation determines that the subject maps to multiple roleTemplates.

[0082] The /system/roleMap/roleTemplate/fullDescription (string minOccurs=0 maxOccurs=1) element contains a description of this role template which specifies the capabilities a caller will have when accessing information through this role. The /system/roleMap/roleTemplate/fullDescription/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /system/roleMap/roleTemplate/fullDescription/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left), and ltr (left to right).

[0083] The /system/roleMap/roleTemplate/method (minOccurs=0 maxOccurs=unbounded) element specifies the methods available within this roleTemplate by name, and by scope. When a subject maps to a roleTemplate, the method in the request must match one of these elements for the message to continue to flow. If the method exists, the data available to the method is a function of the scope referenced by this method combined with an optional scope referenced by the role defined in the roleList.

[0084] The /system/roleMap/roleTemplate/method/@name (string minOccurs=0 maxOccurs=1) element specifies the name of the method. The /system/roleMap/roleTemplate/method/@scopeRef (string minOccurs=0 maxOccurs=1) attribute specifies the scope within this document that is in effect for this method. The /system/methodMap (minOccurs=1 maxOccurs=1) element defines the methodMap. While in most cases, the roleMap section contains a definitive list of methods, these methods are likely to be scattered about the roleMap in various templates. This section contains the definitive non-duplicated list of methods available within the service.

[0085] The /system/methodMap/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0086] The /system/methodMap/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored. The /system/methodMap/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0087] The /system/methodMap/method (minOccurs=0 maxOccurs=unbounded) element defines a method that is available within this service. The /system/methodMap/method/@name (string minOccurs=0 maxOccurs=1) attribute specifies the name of a method available within the service. The /system/methodMap/method/{any} (minOccurs=0 maxOccurs=unbounded) provides for extensibility. The /system/schemaMap (minOccurs=1 maxOccurs=1) element defines the various schema's that define the data structures and shape of information managed by this service. Each schema is defined by its namespace URI, its location, and a preferred namespace alias.

[0088] The /system/schemaMap/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0089] The /system/schemaMap/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0090] The /system/schemaMap/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /system/schemaMap/schema (minOccurs=0 maxOccurs=unbounded) element defines a schema which defines data-structures and the shape of information managed by this service. Multiple schema elements exist for each service, once for each logical grouping of information exposed by the service. The /system/schemaMap/schema/@namespace (anyURI minOccurs=0 maxOccurs=1) attribute specifies the namespace URI of this schema. The /system/schemaMap/schema/@schemaLocation (anyURI minOccurs=0 maxOccurs=1) attribute specifies the location (in the form of a URI) of the resource containing schema. When a schema is reachable through a variety of URIs, one schema element will exist for each location.

[0091] The /system/schemaMap/schema/@alias (string minOccurs=0 maxOccurs=1) attribute specifies the preferred alias that should be used if possible when manipulating information covered by this schema in the context of this service. The /system/schemaMap/schema/{any} (minOccurs=0 maxOccurs=unbounded) provides for extensibility. The /system/wsdlMap (minOccurs=1 maxOccurs=1) element defines the wsdlMap for this service. This map includes the location of WSDL documents, DISCO documents, and WSIL documents for this web service. These documents are used by applications to understand the format of messages that may be sent to the various services. The /system/wsdlMap/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0092] The /system/wsdlMap/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored. The /system/wsdlMap/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0093] The /system/wsdlMap/wsdl (minOccurs=0 maxOccurs=unbounded) element is used to specify the location of a WSDL file for this service. Multiple entries may exist pointing to the same file hosted in multiple locations, or to variations on the content within the WSDL files.

[0094] The /system/wsdlMap/wsdl/@wsdlLocation (anyURI minOccurs=0 maxOccurs=1) attribute is a URI that specifies the location of the WSDL file. The /system/wsdlMap/wsdl/{any} (minOccurs=0 maxOccurs=unbounded) provides for extensibility.

[0095] The /system/wsdlMap/disco (minOccurs=0 maxOccurs=unbounded) element is used to specify the location of a DISCO (web-services discovery) file for this service. Multiple entries may exist pointing to the same file hosted in multiple locations, or to variations on the content within the DISCO files. The /system/wsdlMap/disco/@discoLocation (anyURI minOccurs=0 maxOccurs=1) attribute is a URI that specifies the location of the DISCO file. The /system/wsdlMap/disco/{any} (minOccurs=0 maxOccurs=unbounded) provides extensibility.

[0096] The /system/wsdlMap/wsil (minOccurs=0 maxOccurs=unbounded) element is used to specify the location of a WSIL file for this service. Multiple entries may exist pointing to the same file hosted in multiple locations, or to variations on the content within the WSIL files. The /system/wsdlMap/wsil/@wsilLocation (anyURI minOccurs=0 maxOccurs=1) attribute is a URI that specifies the location of the WSIL file. The /system/wsdlMap/wsil/{any} (minOccurs=0 maxOccurs=unbounded) provides extensibility.

Content Document Subscriptions

[0097] Each of the core services content documents described below (other than myServices, at present) include a subscription node that essentially takes action when items change, such as to propagate information about the change to other services. For simplicity and to avoid redundancy, the meaning of the subscription elements and attributes common to the content documents are described once, rather than for each service. The following table sets forth the subscription elements and attributes common to the core services content documents:

[0098]

	:
	: (other service content)
	:
<m:subscription changeNumber=“...” id=“...” creator=“...”>0..unbounded
	<hs:trigger select=“...” mode=“...”
	baseChangeNumber=“...”>1..1</hs:trigger>
	<hs:expiresAt>0..1</hs:expiresAt>
	<hs:context uri““...”>1..1{any}</hs:context>
	<hs:to>1..1</hs:to>
	</m:subscription>
	:
	: (other service content)
	:

[0099] The /*actual service name*/subscription (minOccurs=0 maxOccurs=unbounded) element defines a subscription node that is designed to be an xdb:blue node which when placed in a content document causes a subscription to be registered, (wherein as used herein, the string “*actual service name*” referred to in this section can be replaced by an appropriate service name, e.g., “myApplicationSettings” or “myContacts” or “myWallet” and so forth). A subscription contains a trigger element which selects a scope of coverage. When items that are under this scope of coverage change, a subscriptionResponse message is generated and sent to the specified destination address.

[0100] The /*actual service name*/subscription/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system, and the attribute is read-only to applications; attempts to write this attribute are silently ignored. The /*actual service name*/subscription/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0101] The /*actual service name*/subscription/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /*actual service name*/subscription/trigger (minOccurs=1 maxOccurs=1) includes the /*actual service name*/subscription/trigger/@select (string minOccurs=0 maxOccurs=1) item, which specifies an XPATH expression that specifies the nodes that are to be selected and watched for changes. The selection may only select xdb:blue nodes, as described above. A s changes in this node set occur, they trigger the generation of a subscription message. These messages are then sent to the SOAP receiver listed in the “to” element.

[0102] The /*actual service name*/subscription/trigger/@mode (string minOccurs=0 maxOccurs=1) attribute specifies whether or not the content of the changes that triggered the subscription are delivered in the subscription message, or if the message simply indicates that something changed under the trigger. The attribute may comprise includeData, namely that the data that changed and caused the subscription to trigger is included in the subscription message. Note that deleted nodes are specified by their id, not by value. Alternatively the attribute may comprise excludeData, whereby the data that changed, causing the subscription to trigger, is not included in the subscription message.

[0103] The /*actual service name*/subscription/trigger/@baseChangeNumber (minOccurs=0 maxOccurs=1) attribute specifies the changeNumber value that the trigger is relative to. All changes between the specified change number, and the current state of the document relative to the selection are transmitted as subscription messages. This allows a client application to establish a subscription relative to some baseline. As in changeQuery, if the baseChangeNumber is way out of date relative to the current state of the document, and the service can not supply the changes in the subscription message, the subscription insert is rejected. A value of zero (0) means that the current values of the selected nodes are transmitted in the subscription message.

[0104] The /*actual service name*/subscription/expiresAt (dateTime minOccurs=0 maxOccurs=1) optional element specifies an absolute time after which the subscription is no longer active. The subscription node is automatically removed when the subscription expires. If this element is missing, the subscription does not expire. The /*actual service name*/subscription/context (minOccurs=1 maxOccurs=1) element returns the context element from the original subscription. Applications should use this element to correlate the subscription response with one of their subscriptions.

[0105] The /*actual service name*/subscription/context/@uri (anyURI minOccurs=0 maxOccurs=) attribute specifies the URI value chosen by the subscriber that is associated with this subscription. The /*actual service name*/subscription/context/{any} (minOccurs=0 maxOccurs=unbounded) including the /*actual service name*/subscription/to (anyURI minOccurs=1 maxOccurs=1) attribute specifies the location that is to receive the subscription message. The value of this element may be hs:myAlerts, whereby this URI indicates that generated subscription messages are to be delivered inside the body of a notification and delivered to the default .NET Alerts service of the creator. Alternatively, the value may be protocol://service, whereby this URI indicates that generated subscription messages are delivered to the specified service at the domain of the creator's platformId. For example, a platformId indicating microsoft.com, and a value in this element of http://subscriptionResponse would cause delivery of the subscription message to http:/subscriptionResponse.microsoft.com. If this value is not specified, then the subscription message is delivered as a notification to the “creator's”.NET Alerts service. The /*actual service name*/{any} (minOccurs=0 maxOccurs=unbounded) field allows for extensibility.

Core Service Schemas

[0106] A number of the services 301-315 (FIG. 2) are referred to as core services, which employ schemas to manage access to the data that most users will likely need. Other services, referred to as extended services 216, will also employ schemas in the same manner, but are more likely to be desirable to certain users and not others. Examples of extended schemas include services such as myPortfolio, myPhotos, myTravel, myMusic, myMovies, myTV, myWishlist, mySchool, myGroceries, myNews, mySports, myTopScores and so on. As will be understood, although the present invention will focus on the core schemas, the present invention is not limited to any schema in particular, but rather is directed to all such schemas. For purposes of organization, the various services and schemas will be described alphabetically by service name, with the one exception being that the “myServices” service will be described first, since applications typically call the myServices service first, in order to communicate with the other services. Note that this is only one exemplary set of core services, and that other core services implementations may include different services, a different combination of these services (i.e. a subset), and/or additional services which may be considered as “core” services. Also, note that the extended services need not be provided by the provider of the core services, e.g., there may be a number of users who subscribe to one companies core services but only subscribe to third party extended services. Likewise, there may be a number of services providers who provide core services or extended services but not both. Thus, it should be understood that a core services provider may also provides extended services, or providers of core or extended services, or both, may be different entities.

myServices

[0107] The myServices schema is an XML schema that describes the list of available other myServices for a given identity (i.e. person, organization, business). The myServices schema essentially serves a directory of what and where each of the myServices logically resides, as well as additional information used to identify the service in the use of general communication. Note that the myServices service that provides the URI (and other needed information) should not be confused with the general concept of “.NET My Services” as described above.

[0108] Issuing a query request to myServices is part of every application's initial responsibility to figure out where a desired service resides. More particularly, the myServices service 314 (FIG. 3) generally allows an application program to obtain the information (e.g., including a URI) needed to connect to another service. It should be noted that there are multiple instances of each such service, e.g., a provider such as MSN.com will have a different myInbox service instance than XYZ.com will have for its myInbox service, and indeed a single provider may have multiple instances of a service. Moreover, a single user may have email accounts at both MSN.com and XYZ.com, and different users may use the same application program to communicate with possibly many other instances of the myInbox service. As a result, an application program normally does not have URIs hard coded therein or initially cached for the many possible instances of the various services, so the application program contacts the myServices service 314 to determine the URI of a service for the current user. The application will of course know or otherwise be able to determine the URI of the myServices service 314. The information returned by the myServices service 314 can be cached thereafter, whereby the application can talk directly to the service desired. However, at any point in time, a given service may respond to the application with a ‘not found here’ type of error, which the application should respond to by again contacting the myServices service, as the user's service may have been moved.

[0109] An application program's query to myServices may result in multiple sets of information (e.g., multiple XML documents) being returned. For example, a user may have different email addresses and get information on different myInbox services returned in response to a single query. An application that can deal with such multiple sets, such as by prompting the user to select one, can use some or all of the information returned. One of the sets of information may be marked as a primary set, whereby applications that can only work with a single set may simply select the primary.

[0110] Thus, the application program 400 queries the myServices service 314, represented in FIG. 5A by the arrow labeled with circled numeral one (1). In addition to the URI of the desired service instance, (e.g., the MyCalendar service 303), in order to communicate with the service 303 the application program 400 needs an identity license, for example a Kerberos ticket that identifies the user, application and credential type. To this end, the myServices service 314 returns the URI, a service principal name (spn), and realm information that corresponds to a Kerberos domain controller (KDC) 500, as represented in FIG. 5A by the arrow labeled with circled numeral two (2). The application program 400 uses the spn to obtain the identity license from the KDC 500 based on the realm information, as represented via the arrows labeled three (3) and four (4), wherein a KDC 500 issues tickets for services in a particular realm 502. The application program 500 may then properly communicate with the myCalendar service 303 (arrow labeled five (5)).

[0111] In an alternative implementation, represented in FIG. 5B, for efficiency, an instance of the myServices service 314 may be part of a realm 504 having a KDC 506. In response to the query (the arrow labeled one (1)), if the realm that the myServices service is part of is the same as the realm that would be returned to the application program 400, the myServices service 314 will instead automatically obtain the ticket for the application program 400, as represented in FIG. 5B via the arrows labeled two (2) and three (3). The license ticket is then directly returned, (arrow labeled four (4)), whereby the application program 500 may then properly communicate with the myCalendar service 303 (arrow labeled five (5)). Note that it is typically far faster for the myServices service to communicate with the KDC in its realm (e.g., in the same datacenter) than for an application program to do so over an Internet connection. It should be noted that a myServices instance can also be associated with multiple KDCs, and does not have to belong to any one realm. For example, a myServices service may be able to communicate with a Passport KDC, an MSN.com KDC, a hotmail.com KDC, and so forth. When an application program query results in a realm that corresponds to one of these KDCs, the myServices service can obtain the license ticket directly, as described above.

[0112] In most cases, the myServices entry serves as the definitive information for a given user and the service information. However, one possibility is that a myServices instance will not know the specifics of a particular user's needed information, e.g., the desired service's URI, realm and/or spn. In such an event, the myServices instance can refer the application program to another myServices instance by returning referral information (in a refer field) to the application program in response to the query. To this end, when a <refer> tag is found within a service entry, this means that the entry is a referral, and the <to> element actually points to another second tier myServices service. This capability is important for the ability to distribute the lookup information instead of having one centralized logical point of failure and updates. Ultimately the application program will obtain the address and other information of the desired .NET MyServices service. Note that it is possible for a response to include a referral and also include a license ticket, since a myServices instance may be connected to the appropriate KDC, but not have the URI of the desired service.

myServices/Roles

[0113] The myServices service controls access by using the roleTemplates, rt0, rt1, rt2, rt3, and rt99, using the following scopes:

[0114]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>
	<hs:shape base=t>
	</hs:shape>
</hs:scope>
scope onlySelfElements
<hs:scope id=a159c93d-4010-4460-bc34-5094c49c1633>
	<hs:shape base=nil>
	<hs:include select=//*[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlySelfSubscriptionElements
<hs:scope id=b7f05a6d-75cd-4958-9dfb-f532ebb17743>
	<hs:shape base=nil>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlyPublicElements
<hs:scope id=da025540-a0c0-470f-adcf-9f07e5a5ec8f>
	<hs:shape base=nil>
	<hs:include select=//*[cat/@ref=‘hs:public’]/>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0115] The myServices roleTemplate rt0 role gives give complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myServices service through that method while mapped to this roleTemplate.

[0116]

TABLE
myServices roleTemplate rt0
	method	scope/name
	query	allElements
	insert	allElements
	replace	allElements
	delete	allElements
	update	allElements

[0117] The myServices roleTemplate rtl role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. Applications may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myServices service through that method while mapped to this roleTemplate:

[0118]

TABLE
myServices roleTemplate rt1
	method	scope/name
	Query	allElements
	Insert	onlySelfElements
	Replace	onlySelfElements
	Delete	onlySelfElements

[0119] The myServices roleTemplate rt2 gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the MyServices service through that method while mapped to this roleTemplate.

[0120]

TABLE
myServices roleTemplate rt2
	method	scope/name
	query	allElements
	insert	onlySelfSubscriptionElements
	replace	onlySelfSubscriptionElements
	delete	onlySelfSubscriptionElements

[0121] The myServices roleTemplate rt3 gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myServices service through that method while mapped to this roleTemplate:

[0122]

TABLE
myServices roleTemplate rt3
	method	scope/name
	query	onlyPublicElements

[0123] The myServices roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99. The following table illustrates that there are no available methods and the scope in effect when accessing the myServices service through that method while mapped to this roleTemplate (note that in other services described herein, such an empty table will not be repeated):

[0124]

TABLE
myServices roleTemplate rt99
	method	scope/name

myServices/Content

[0125] The content document is an identity centric document. It's content and meaning is a function of the puid used to address the service. Accessing the document is controlled by the associated roleList document.

[0126] This schema outline illustrates the layout and meaning of the information found in the content document for the MyServices service:

[0127]

<m:.myServices changeNumber=“...” instanceId=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myServies”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core“>1..1
	<m:service name=“...”changeNumber=“...” id=“...”
	creator=“...”>0..unbounded
	<m:cat ref=“...”>0..unbounded</m:cat>
	<m:key puid=“...” instance=“...” cluster=“...”>0..1</m:key>
	<m:refer>0..1</m:refer>
	<m:to>1..1</m:to>
	<m:spn>1..1</m:spn>
	<m:realm>1..1</m:realm>
	{any}
	</m:service>
	{any}
</m:.myServices>

[0128] The meaning of the attributes and elements shown in the table are set forth below, wherein in the syntax used in the table, boldface type corresponds to a blue node, and underlined type to a red node, as described above, and the minimum occurrence information (0, 1) indicates whether an element or attribute is required or optional, and maximum occurrence information (1, unbounded) indicates whether one or many are possible.

[0129] The /myServices (minOccurs=1 maxOccurs=1) element encapsulates the content document for the service. The /myServices/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0130] The /myServices/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a user is provisioned for a particular service.

[0131] The /myServices/service (minOccurs=0 maxOccurs=unbounded) node includes a /myServices/service/@name (string minOccurs=0 maxOccurs=1) element which contains the name of the service being accessed by this request message. For example, to access the .NET Profile service, this attribute will have the value “myProfile”.

[0132] The /myServices/service/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0133] The /myServices/service/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0134] The /myServices/service/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0135] The /myServices/service/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid.

[0136] The /myServices/service/cat/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined below in the myCategories section of the present application.

[0137] The /myServices/service/key (minOccurs=0 maxOccurs=1) element specifies key information used to zoom in on a document being manipulated. This information includes the identifier (puid) of the entity that owns the document, the instance identifier of the document, and the cluster or partition key used to locate the machine resources that hold the document.

[0138] In certain situations, a client will want to send the same message to a number of instances of a particular service. In order to do this, the client may repeat this element multiple times. The cluster attributes in all elements must match each other, but the puid and instance attributes may differ. A unique response message is generated for each key specified. The entire contents of this element come from the myServices service 314 (FIG. 3).

[0139] The /myServices/service/key/@puid (string minOccurs=0 maxOccurs=1) element specifies the PUID of the entity that “owns” the service being accessed. In the case of a “myProfile” service, this element is equivalent to the “my”. The puid may be used to automatically connect to another set of information for the user. By way of example, consider a user with a two puids, such as a work puid and a home puid. The puid field can contain the user's other puid, which allows one or more instances of a desired service to operate as if the user connected with both.

[0140] The /myServices/service/key/@instance (string minOccurs=0 maxOccurs=1) element specifies the particular instance of the service for this id being accessed. For example, if a given id is provisioned with multiple .NET Calendar documents on the same cluster and in the same data center, the documents would differ only by this value. In other words, while services are generally thought of as constructing a document per user identifier, in actuality more than one instance may exist for a given user. For example, a user, with the same puid, may have personal calendar, a work calendar, a top secret calendar, and so forth, each of which corresponds to an instance. The instance id identifies from which instance a user wants to access data.

[0141] The /myServices/service/key/@cluster (string minOccurs=0 maxOccurs=1) element specifies information used by the .NET My Services system to locate the document on a particular back-end server or database. It is used as the virtual partition key for the document being addressed. This technique is preferable to computing this partition key based on some hash of the puid/instance. If the data is later moved to another back-end server or database, the application will need to go back to myServices to obtain its new location.

[0142] The /myServices/service/refer (string minOccurs=0 maxOccurs=1) element specifies whether the fields below are for a referral, as described above.

[0143] The /myServices/service/to (string minOccurs=1 maxOccurs=1) element specifies the destination URI (typically a URL), e.g., either of the desired service or of a referral address.

[0144] The /myServices/service/spn (string minOccurs=1 maxOccurs=1) element specifies the spn needed that may be needed to obtain a license from a KDC, as described above with reference to FIG. 5A. The /myServices/service/realm (string minOccurs=1 maxOccurs=1) element specifies the authentication realm for the spn in question, as also described above.

[0145] The /myServices/service/{any} (minOccurs=0 maxOccurs=unbounded) and /myServices/{any} (minOccurs=0 maxOccurs=unbounded) fields allow extensibility of the myServices service. For example, if a license was returned directly by the myServices service as described above with respect to FIG. 5B, then the license data may be returned in an {any} field. Alternatively, a dedicated <license> field may be built into the myServices content document.

myServices/System

[0146] The myServices system document includes the set of base items common to each of the .NET My Services, as described above. At present, the myServices system document is not optionally extended. Hereinafter, only services with system documents having extended items will include such a separate system section, although it should be understood that each service has a system document corresponding to at least the base system document.

my/Alerts

[0147] The Microsoft®.NET Alerts service, generally referred to as myAlerts, provides a single point where short messages can be sent to a specific user and transparently routed to that user's applications or devices. This particular service uses an XML schema to describe Alerts, and the methods by which Alerts can be sent and received. In general, the myAlerts service processes alerts (also referred to as notifications and/or events).

[0148] In keeping with the present invention, an alert is defined as embeddable XML, specifying both standard schema and extensible problem-domain schema, using the problem-domain schema as alert typing. The standard schema is generally directed to conveying alerts, regardless of what the alert is trying to convey. The problem-domain schema extension is used in a dynamically programmable Alert processing mechanism to control alert routing. Like other .NET My Services, .NET Alerts is designed to service the user instead of a particular device or application. Although alerts are posted to a single location, the messages are transparently routed to one or more of the user's applications or devices. The logic for deciding how, where, and when a message is delivered can be customized to meet the needs of a particular user, device, or application.

[0149] The myAlerts service includes mechanisms to deliver alerts, comprising a basic model mechanism that provides the baseline functionality of sending and receiving alerts. A streams model mechanism includes more robust features, such as filtering, buffering, and persistence, as well as more refined control over the routing of alerts.

[0150] As used herein, a client is any entity that can issue an XMI request to the .NET Alerts service. Clients can send or receive alerts, wherein an alert typically comprises a short XML message delivered to one or more users by .NET Alerts. A receiver is a .NET My Services user who has one or more applications that can receive alerts. Such an application is referred to herein as a userAgent. A userAgent includes any code on any device that can communicate with .NET Alerts.

[0151] The myAlerts service provides a variety of ways to communicate with userAgents. For example, as generally represented in FIG. 7, a sender 700 may send an alert 702 by issuing an XMI request to the myAlerts service 301. The sender 700 can send alerts to the sender's own user, or to another user. Senders and most userAgents are clients because they issue XMI requests to the myAlerts service to send or receive alerts. Because myAlerts supports non-XMI protocols to deliver alerts to userAgents, some userAgents are not clients.

[0152] UserAgents 716-718 create connections 712-714, respectively, to receive alerts. Each connection (e.g., 712) has a query that selects which alerts the connection 712 will forward to its respective userAgent 716. The connection 712 will use a particular protocol to deliver alerts to the userAgent 716; different connection types may provide different protocols for a userAgent. As the .NET Alerts service receives alerts, it routes them to zero or more connections, depending on the queries for each connection.

[0153] To send an alert 702, a client sender 700 issues a notify method request to a user's myAlerts service 301. To receive alerts, a userAgent (e.g., 716) issues an insert method request to create a connection 716 in the myAlerts content document, and then processes the resulting connection protocol to receive incoming alerts. Different connection types can support different alerts and userAgent protocols (for example, SOAP/XMI over HTTP, TCP/DIME, and UDP), and can also include SIP or other non-XMI protocols. Connections generally fall into Push Connections, wherein the myAlerts service proactively pushes an alert to a userAgent, or Pull Connections, wherein the userAgent proactively pulls an alert from the myAlerts service. This requires some alert buffering.

[0154] In general, each alert 702 is a snippet of XML passed to and from the myAlerts service 301 embedded within XMI method request and response packets. The lifetime (and position) of an alert is transitory. Therefore, alerts are not part of the user content document. Alerts are proactively sent to the myAlerts service or to userAgents with the notify method, described below. Alerts are proactively pulled from the myAlerts service with the poll method, also described below.

[0155] Argots 703 are XML blobs (e.g., strongly-named {any} fields) that may be placed in an alert to convey problem domain-specific data. The outer element name defines the argot; the inner contents of the argot are opaque to general myAlerts processing. At present, argots may be represented formally and informally. An argot is formally declared through an outer argot element, and its name is specified through the argotURI attribute. The actual content of the argot is specified in sub-elements. The formal representation of argots may change to the informal representation in future versions. Informally declared argots are simply declared as an XML element. In this case, the argot name is the name of that element. Such an argot can have sub-elements, as appropriate.

[0156] The myAlerts service expects informal argots within the contents element of an alert. The xpQuery element for both streams and connections defines a query against the argot names within the contents element. For example, an xpQuery value of “humanReadable” in a connection causes that connection to get only alerts that contain the humanReadable argot in their contents. To match all argots, an asterisk (“*”) may be specified in the xpQuery value.

[0157] The myAlerts service expects formal argots in some of the stream and connection document methods. For example, the push connection requires the pushConnectionParameters formal argot in insert and replace methods, and generates it for query methods.

[0158] As generally represented in FIG. 7, a streams model is also provided. Unlike the basic model, the streams model provides a mechanism to filter, buffer, persist, or intelligently control the routing of alerts. A stream of alerts is a set of alerts that match an argot query. The argot query specifies a relation of argot types; an alert is in the stream if it contains argots that match the stream query. To include alerts in a stream, an asterisk (“*”) may be used, or a set of argot types (for example, “humanReadable”) can be specified to include a subset.

[0159] A stream (e.g., 705) is an object inside a user's myAlerts service 301 that defines and manages a stream of alerts as they are routed to the user's connections. Clients can create and provision one or more streams to control the alert routing for a user. A user may have multiple streams 705-707 to control different streams of alerts. Multiple streams are supported because a user will often receive different types of alerts, each requiring its own filtering, buffering, and so on. For example, the myAlerts service 301 may focus on human-oriented alerts to implement a stream that controls alerts containing the humanReadable argot. Other services or applications will define their own argots, and will want to control the processing of their alerts.

[0160] Clients create, manage, and delete streams through XMI requests to a user's .NET Alerts content document. Generally, a stream operates in four steps:

• • [0161] 1. Instantiate—the stream is instantiated from a stream class and provisioned to control its behavior.
  • [0162] 2. Select—the stream will select the alerts to process as they arrive.
  • [0163] 3. Process—the stream processes its selected alerts.
  • [0164] 4. Route—the stream routes its alerts to other streams or to connections for delivery to one or more userAgents.

[0165] These steps are formalized in three objects inside the alert routing, namely streamFork 704, stream (e.g., the stream 706) and connectionFork (710). When an alert 702 is received by the myAlerts service 301, the streamFork 704 decides the order in which to invoke streams 705-707 on the alert 702. When invoked, each stream will determine whether to handle the alert and whether to continue or stop the streamFork processing. A stream (e.g., the stream 706) can handle or ignore an alert, and can also allow or inhibit later streams from handling the alert.

[0166] Each of the streams 705-707 then applies its processing algorithm and state to the alerts they handle. A stream can reroute the alert to other streams by continuing or restarting the streamFork process. A stream can deliver an alert by passing it on to the connections through the connectionFork 710.

[0167] The connectionFork 710 controls communication between streams and connections 712-714, processing and optimizing execution of the connection queries to match alerts to the appropriate connections. Conceptually, as represented in FIG. 7, alerts (e.g., the alert 702) moves forward from the sender 700, through the streamFork 704, through zero or more streams 705-707, through the connectionFork 710, through zero or more connections 712-714, to connected userAgents 716-718. Streams 705-707 can push alerts to connections 712-714 or connections 712-714 can pull alerts from streams 705-707. This will match the type of connections (that is, push or pull).

[0168] Stream types provide different alert handling algorithms. Five possible stream capabilities includes:

• • [0169] 1. Simple Stream—selects a set of alerts and immediately passes them to any/all connections. This is the default stream for myAlerts and is always implemented by the streamFork. It provides no buffering; alerts are immediately delivered through existing connections and then discarded. When they are not connected, userAgents miss all alerts.
  • [0170] 2. Buffering Stream—selects a subset of alerts and buffers them for some period of time. Alerts are passed to a connection when the connection can process the alert. Stream buffering allows a connection to deliver alerts received before the connection was created or across delays and failures in the connection's protocol.
  • [0171] 3. Privacy Stream—selects and filters a subset of alerts according to a set of privacy or safety rules. The stream will choose to discard or deliver an alert based on its rules. Typically, a privacy stream will take sole possession of its subset of alerts.
  • [0172] 4. Routing Stream—selects a subset of alerts and changes their routing, controlling which succeeding streams or connections will process the alert. Routing streams can insert or remove alerts from the alert streams.
  • [0173] 5. External Stream—delegates the actual stream algorithm and state to an object external to the myAlerts provider. The external stream type specifies and implements an XMI application programming interface (API) for the external object.

[0174] The myAlerts architecture declares the ordering and non-ordering of alert delivery through a connection. However, alert buffering, multiple streams, and intra-user federation can make it difficult to guarantee ordering, and arbitrary rerouting of alerts by routing streams can make ordering impossible. A virtual stream is the aggregate set of alerts delivered through a particular connection. The order in a virtual stream will be defined by the set of streams contributing alerts to the virtual stream. Simple, buffering, and privacy streams are required to maintain a standard ordering of oldest to newest alerts in a virtual stream. Routing and external streams are also required to maintain that order. Alerts that are inserted into the stream need to be new; an old alert cannot be reinserted out of order or multiple times.

[0175] One implementation of myAlerts provides a streamDefault stream class, which always exists and is not reflected in the user's content document, and a streamBuffer stream class. This stream will buffer up to one-hundred of the alerts it selects in memory. Note the number one-hundred is arbitrary, and was just selected as a suitable number for this implementation.

[0176] Two connection classes are implemented in one current implementation of myAlerts, namely a pushConnection, wherein the connection will push an alert to an URL by issuing an XMI notify method request, and a pullConnection, wherein the userAgent will issue XMI poll method requests to the connection to retrieve alerts.

[0177] The alert schema contains both standard and problem-domain specific portions. The present invention types the problem-domain portions as argots and allows that typing to define the essential semantic naming shared between alert senders and receivers.

[0178] The schema for the alert processing mechanism contains both stream objects which control alert processing within our service and connection objects which control delivery and protocol to external user agents. Both types of objects select and process alerts based on the argots contained in each alert, through the argotQuery element that specifies a standing query against received and persisted alerts.

[0179] In addition, new methods are provided, described below, including:

• • [0180] 1. Notify—to transmit one or more alerts from a sender to a receiver
  • [0181] 2. Poll—for a user agent to pull one or more alerts through a connection from our service
  • [0182] 3. Route—to perform complex and privileged routing within our service
  • [0183] 4. Do—to request a stream or connection object to perform an action
    myAlerts/Roles

[0184] The myAlerts service controls access by using the rt0, rt3 and rt99 roleTemplates, using the following scopes:

[0185]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>
	<hs:shape base=t>
	</hs:shape>
</hs:scope>
scope onlySelfElements
<hs:scope id=a159c93d-4010-4460-bc34-5094c49c1633>
	<hs:shape base=nil>
	<hs:include select=//*[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlySelfSubscriptionElements
<hs:scope id=b7f05a6d-75cd-4958-9dfb-f532ebb17743>
	<hs:shape base=nil>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlyPublicElements
<hs:scope id=da025540-a0c0-470f-adcf-9f07e5a5ec8f>
	<hs:shape base=nil>
	<hs:include select=//*[cat/@ref=‘hs:public’]/>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0186] The myAlerts roleTemplate rt0 role gives complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myAlerts service through that method while mapped to this roleTemplate:

[0187]

TABLE
myAlerts roleTemplate rt0
	method	scope/name
	query	allElements
	insert	allElements
	replace	allElements
	delete	allElements
	update	allElements
	update	allElements
	notify	allElements
	poll	allElements

[0188] The myAlerts roleTemplate rt3 role gives limited read access to information within the content document that is categorized as “public”. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myAlerts service through that method while mapped to this roleTemplate:

[0189]

TABLE
myAlerts roleTemplate rt3
	method	scope/name
	query	onlyPublicElements
	Notify	allElements

[0190] The myAlerts roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99.

myAlerts/Notification

[0191] Each alert comprises XML embedded within an XMI method packet or privately stored by the .NET Alerts service. The following is the structure of an alert:

[0192]

<m:notification id=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>0..unbounded
	<m:from>1..1
	<m:identityHeader type=“...”>0..1
	<m:onBehalfOfUser>1..1</m:onBehalfOfUser>
	<m:licenseHolder>1..1</m:licenseHolder>
	<m:platformId>1..1</m:platformId>
	</m:identityHeader>
	<m:expiresAt ttl=“...” onDate=“...”
	replace=“...”>0..1</m:expiresAt>
	<m:acknowledge>0..1</m:acknowledge>
	<m:category id=“...”>0..1</m:category>
	</m:from>
	<m:to>0..1
	<m:originalUser>0..1</m:originalUser>
	</m:to>
	<m:contents>1..1 {any}</m:contents>
	<m:routing>1..1
	<m:timestamp>0..1</m:timestamp>
	<m:hops>0..1</m:hops>
	</m:routing>
</m:notification>

[0193] The /notification (minOccurs=0 maxOccurs=unbounded) provides for zero or more alerts in the buffer of the streamBuffer stream. The /notification/@id (string minOccurs=0 maxOccurs=1) is an identifier of the alert (notification), while the /notification/from (minOccurs=1 maxOccurs=1) tag contains data from the sender, including sender authentication as well as preferences and requests from the sender.

[0194] The /notification/from/identityHeader (minOccurs=0 maxOccurs=1) includes /notification/from/identityHeader/@type (string minOccurs=0 maxOccurs=1) and /notification/from/identityHeader/onBehalfOfUser (minOccurs=1 maxOccurs=1). The uuidType is used to specify a universally unique identifier (UUID). The /notification/from/identityHeader/licenseHolder (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID).

[0195] The /notification/from/identityHeader/platformId (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID). The /notification/from/expiresAt (string minOccurs=0 maxOccurs=1) is directed to expiration time of an alert, including /notification/from/expiresAt/@ttl (string minOccurs=0 maxOccurs=1), /notification/from/expiresAt/@onDate (string minOccurs=0 maxOccurs=1) and /notification/from/expiresAt/@replace (string minOccurs=0 maxOccurs=1).

[0196] The /notification/from/acknowledge (string minOccurs=0 maxOccurs=1) field contains information related to acknowledging the alert, while /notification/from/category (minOccurs=0 maxOccurs=1) and /notification/from/category/@id (string minOccurs=0 maxOccurs=1) contains category information.

[0197] The /notification/to (minOccurs=0 maxOccurs=1) tag contains the data pertaining to the receiver. This data can be set by the sender or by any processing/routing agent between the sender and the receiver. The /notification/to/originalUser (minOccurs=0 maxOccurs=1) element defines the original receiver of the alert. A routing agent may change (forward or fan out) an alert to other receivers. If so, it should add this element to the alert.

[0198] The /notification/contents (minOccurs=1 maxOccurs=1) element contains the problem domain-specific data to be conveyed to the receiver. Each child element of the contents element is an argot, a problem domain-specific strongly-typed XML blob. Streams and connections query against the element names of these blobs when selecting alerts they will process. The /notification/contents/{any} (minOccurs=0 maxOccurs=unbounded) contains the argot data.

[0199] The /notification/routing (minOccurs=1 maxOccurs=1) tag contains any routing data inserted by the myAlerts routing process. The /notification/routing/timestamp (string minOccurs=0 maxOccurs=1) element contains the timestamp of when the alert was received by the myAlerts service. The /notification/routing/hops (string minOccurs=0 maxOccurs=1) element defines the actors that have processed the alert to date. This data can be used by the myAlerts service to recognize and stop infinite loops.

[0201] The myAlerts content document comprises the user content document for alert routing. It contains streams, connections, and preferences (general provisioning). The document does not contain a list of alerts, as alerts are transitory. NotifyRequest, route, and PollRequest are used to send and receive alerts, as described below.

[0202] The /myAlerts/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0203] The /myAlerts/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a particular service is provisioned for a user.

[0204] The /myAlerts/stream (minOccurs=1 maxOccurs=unbounded) is directed to a stream, which comprises an internal object that processes alerts before they are routed to connections. Streams can buffer or reroute. The /myAlerts/stream/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored. The /myAlerts/stream/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0205] The /myAlerts/stream/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myAlerts/stream/class (string minOccurs=1 maxOccurs=1) defines what kind of stream this is. The /myAlerts/stream/expiration (dateType minOccurs=0 maxOccurs=1) specifies the lifetime of a connection in absolute time (GMT). This can be used to clean up the content document. The /myAlerts/stream/position (string minOccurs=1 maxOccurs=1) defines where the stream fits into the streamFork processing.

[0206] The /myAlerts/stream/argotQuery (string minOccurs=0 maxOccurs=1) field maintains the stream's query against incoming alerts. The query specifies the argot name(s) that enable selection (a logical OR of the named argots). This is optional based on the streamClass (e.g., a stream may do its own selection processing instead of or in addition to the standard stream alert query). If not present, the query defaults to all alert argots (“*”)

[0207] The /myAlerts/stream/argot (minOccurs=0 maxOccurs=unbounded) field comprises an optional provisioning argot for the stream, and is dependent on the stream class. The /myAlerts/stream/argot/@argotURI (anyURI minOccurs=1 maxOccurs=1) URI uniquely identifies the type of argot and points to a location containing the XSD for this argot. The /myAlerts/stream/argot/{any} (minOccurs=0 maxOccurs=unbounded) field contains argot data.

[0208] The /myAlerts/connection (minOccurs=0 maxOccurs=unbounded) uses the following abbreviations: CXN (for a connection, which exists inside of the .NET Alerts service as described above with reference to FIG. 7), and UA (for a UserAgent, which exists outside of the .NET Alerts service). There are two primary types of connections, namely push, wherein alerts are pushed by CXN to UA, and pull, wherein alerts are downloaded by the UA by issuing a request to CXN. The response contains the alerts. A CXN is created (added to the .NET Alerts content document) either by the UA directly or by some entity acting on behalf of the UA. In order to transfer the alerts, a session, either persistent or transient, is established between CXN and UA. In cases in which sessions are transient, the CXN persists. Establishment of a session can be initiated by a CXN or the UA, when the CXN is created or based on, for example, a timer or some signaling mechanism between CXN and UA. The session can be closed by either entity after a period of time (including 0). The following are different models of UA-CXN interaction: 1) UA establishes a session with a CXN and pulls alerts from CXN; 2) UA establishes a session with a CXN and the CXN pushes alerts to the UA; 3) CXN establishes a session with a UA and the UA pulls alerts; 4) CXN establishes a session with a UA and pushes alerts to UA; 5) UA polls the CXN periodically on a timer and UA will initiate process 1) or 2); and 6) CXN polls the UA when alerts arrive or periodically on a timer. When there are pending alerts in the queue, UA will initiate process 1) or 2).

[0209] The /myAlerts/connection/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0210] The /myAlerts/connection/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0211] The /myAlerts/connection/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myAlerts/connection/class (string minOccurs=1 maxOccurs=1) element specifies the class of a connection (for example, Push over Soap-RP or Pull over Soap-RP).

[0212] The /myAlerts/connection/status (string minOccurs=1 maxOccurs=1) contains flags indicating the current status of the connection. This can be used by the Stream modules to do traffic management, buffering, generate non-delivery and delayed delivery reports for the sender. The /myAlerts/connection/characteristics (string minOccurs=1 maxOccurs=1) field contains information about the nature of the connection, used mainly by the Stream modules. Reliable can mean it supports ACKs, while unreliable means it is fire-and-forget. Characteristics may include the type of polling used (Connection vs. UserAgent).

[0213] The /myAlerts/connection/expiration (dateType minOccurs=1 maxOccurs=1) field contains the lifetime of a connection in absolute time (GMT). This can be used to clean up the content document. The /myAlerts/connection/argotQuery (string minOccurs=1 maxOccurs=1) field maintains the connection's query against incoming alerts. The query specifies the argot name(s) that enable selection (a logical OR of the named argots).

[0214] The /myAlerts/connection/argot (minOccurs=0 maxOccurs=unbounded) contains an optional provisioning argot for the connection. This is dependent on the connection class. The /myAlerts/connection/argot/@argotURI (anyURI minOccurs=1 maxOccurs=1) URI uniquely identifies the type of argot and points to a location containing the XSD for this argot. The /myAlerts/connection/argot/{any} (minOccurs=0 maxOccurs=unbounded) contains the argot data.

myAlerts—Domain-Specific Methods

[0215] The myAlerts service uses the standard methods, and domain-specific methods notify and poll. The notify method allows a client to send an alert to the userAgents connected for the user. The poll method allows a userAgent to proactively pull an alert through a connection.

[0216] The myAlerts/notify Method sends one or more alerts to the receiver. If the receiver is the .NET Alerts service, the alert(s) will be delivered to the appropriate set of connected userAgents. The myAlerts/notifyRequest method is accessed using a request message, and in response may generate a response message or a SOAP Fault message. The following sample document fragments illustrate the structure and meaning of the elements and attributes in the request and response messages.

[0217] The following table and accompanying description thereafter describes the request message for this method:

[0218]

<m:notifyRequest
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:notification id=“...“>0..unbounded
	<m:from>1..1
	<m:identityHeader type=“...”>0..1
	<m:onBehalfOfUser>1..1</m:onBehalfOfUser>
	<m:licenseHolder>1..1</m:licenseHolder>
	<m:platformId>1..1</m:platformId>
	</m:identityHeader>
	<m:expiresAt tth=“...” onDate=“...”
	replace=“...”>0..1</m:expiresAt>
	<m:acknowledge>0..1</m:acknowledge>
	<m:category id=“...”>0..1</m:category>
	</m:from>
	<m:to>0..1
	<m:originalUser>0..1</m:originalUser>
	</m:to>
	<m:contents>1..1{any}</m:contents>
	<m:routing>1..1
	<m:timestamp>0..1</m:timestamp>
	<m:hops>0..1</m:hops>
	</m:routing>
	</m:notification>
</m:notifyRequest>

[0219] The /notifyRequest (minOccurs=1 maxOccurs=1) method attempts to send the enclosed alerts using standard routing by .NET Alerts. There can be one or more notification elements specified. If none is specified, the notify request should be interpreted as a query about whether the receiver is willing to accept alerts from this sender. The /notifyRequest/notification (minOccurs=0 maxOccurs=unbounded) specifies an alert to be delivered. The /notifyRequest/notification/@id (string minOccurs=0 maxOccurs=1) and /notifyRequest/notification/from (minOccurs=1 maxOccurs=1) tag contains all data from the sender, including sender authentication as well as preferences and requests from the sender.

[0220] The /notifyRequest/from/identityHeader (minOccurs=0 maxOccurs=1) includes /notifyRequest/from/identityHeader/@type (string minOccurs=0 maxOccurs=1) and /notifyRequest/from/identityHeader/onBehalfOfUser (minOccurs=1 maxOccurs=1). The uuidType is used to specify a universally unique identifier (UUID). The /notifyRequest/from/identityHeader/licenseHolder (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID).

[0221] The /notifyRequest/from/identityHeader/platformId (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID). The /notifyRequest/from/expiresAt (string minOccurs=0 maxOccurs=1) is directed to expiration time of an alert, including /notifyRequest/from/expiresAt/@ttl (string minOccurs=0 maxOccurs=1), /notifyRequest/from/expiresAt/@onDate (string minOccurs=0 maxOccurs=1) and /notifyRequest/from/expiresAt/@replace (string minOccurs=0 maxOccurs=1).

[0222] The /notifyRequest/from/acknowledge (string minOccurs=0 maxOccurs=1) field contains information related to acknowledging the alert, while /notifyRequest/from/category (minOccurs=0 maxOccurs=1) and /notifyRequest/from/category/@id (string minOccurs=0 maxOccurs=1) contains category information.

[0223] The /notifyRequest/to (minOccurs=0 maxOccurs=1) tag contains the data pertaining to the receiver. This data can be set by the sender or by any processing/routing agent between the sender and the receiver. The /notifyRequest/to/originalUser (minOccurs=0 maxOccurs=1) element defines the original receiver of the alert. A routing agent may change (forward or fan out) an alert to other receivers. If so, it should add this element to the alert.

[0224] The /notifyRequest/contents (minOccurs=1 maxOccurs=1) element contains the problem domain-specific data to be conveyed to the receiver. Each child element of the contents element is an argot, a problem domain-specific strongly-typed XML blob. Streams and connections query against the element names of these blobs when selecting alerts they will process. The /notifyRequest/contents/{any} (minOccurs=0 maxOccurs=unbounded) contains the argot data.

[0225] The /notifyRequest/routing (minOccurs=1 maxOccurs=1) tag contains any routing data inserted by the myAlerts routing process. The /notifyRequest/routing/timestamp (string minOccurs=0 maxOccurs=1) element contains the timestamp of when the alert was received by the myAlerts service. The /notifyRequest/routing/hops (string minOccurs=0 maxOccurs=1) element defines the actors that have processed the alert to date. This data can be used by the myAlerts service to recognize and stop infinite loops.

[0226] If the method causes a failure response to be generated, the failure is noted by generation of a SOAP Fault message. Failures can include a failure to understand a header marked as “s:mustUnderstand”, a .NET My Services standard error, security violation, load-balance redirect, or any service-specific severe error condition.

[0227] The myAlerts/poll Method poll method can be used on a connection in .NET Alerts to retrieve alerts that satisfy the xpQuery specified for the connection. Succeeding poll methods on a connection will return alerts in a first-in (received), first-out (delivered) order for that connection. Alerts will be buffered (that is, stored in the .NET Alerts service after receipt and later delivered by a poll method invocation) only if a suitable buffering stream has been configured.

[0228] The myAlerts/pollRequest method is accessed using a request message, and in response may generate a response message or a SOAP Fault message. The following table and accompanying description thereafter describes the request message for this method:

[0229]

m:pollRequest
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:parkInterval>0..1</m:parkInterval>
</m:pollRequest>

[0230] The /pollRequest (minOccurs=1 maxOccurs=1) method can be invoked on a connection. If there is a new alert in the buffer stream, it will be returned in the pollResponse message. The pollRequest will immediately return a response about whether there is a pending alert. However, if the optional parkInterval element is specified, then the response can take up to parkInterval milliseconds before returning when there are no new alerts in the buffer stream. The /pollRequest/parkInterval (string minOccurs=0 maxOccurs=1) field specifies the time, wherein the unit of time for parkInterval is milliseconds.

[0231] Upon successful completion of this method, a response message, myAlerts/pollResponse, is generated. The format of the response message is described below, wherein the number of alerts returned in the response can be zero or one:

[0232]

<m:pollResponse
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:notification id=“...”>0..1
	<m:from>1..1
	<m:identityHeader type=“...”>0..1
	<m:onBehalfOfUser>1..1</m:onBehalfOfUser>
	<m:licenseHolder>1..1</m:licenseHolder>
	<m:platformId>1..1</m:platformId>
	</m:identityHeader>
	<m:expiresAt ttl=“...” onDate=“...”
	replace=“...”>0..1</m:expiresAt>
	<m:acknowledge>0..1</m:acknowledge>
	<m:category id=“...”>0..1</m:category>
	</m:from>
	<m:to>0..1
	<m:originalUser>0..1</m:origmalUser>
	</m:to>
	<m:contents>1..1{any}</m:contents>
	<m:routing>1..1
	<m:timestamp>0..1</m:timestamp>
	</m:hops>0..1</m:hops>
	</m:routing>
	</m:notification>
</m:pollResponse>

[0233] The /pollResponse (minOccurs=1 maxOccurs=1) response contains zero or one new alerts in the buffer stream. The /pollResponse/notification (minOccurs=0 maxOccurs=1) comprises a new alert contained in the buffer stream. The /pollResponse/notification/@id (string minOccurs=0 maxOccurs=1) contains an identifier

[0234] The /pollResponse/notification/from (minOccurs=1 maxOccurs=1) tag contains data from the sender, including sender authentication as well as preferences and requests from the sender. The /pollResponse/from/identityHeader (minOccurs=0 maxOccurs=1) includes /pollResponse/from/identityHeader/@type (string minOccurs=0 maxOccurs=1) and /pollResponse/from/identityHeader/onBehalfOfUser (minOccurs=1 maxOccurs=1). The uuidType is used to specify a universally unique identifier (UUID). The /pollResponse/from/identityHeader/licenseHolder (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID).

[0235] The /pollResponse/from/identityHeader/platformId (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID). The /pollResponse/from/expiresAt (string minOccurs=0 maxOccurs=1) is directed to expiration time of an alert, including /pollResponse/from/expiresAt/@ttl (string minOccurs=0 maxOccurs=1), /pollResponse/from/expiresAt/@onDate (string minOccurs=0 maxOccurs=1) and /pollResponse/from/expiresAt/@replace (string minOccurs=0 maxOccurs=1).

[0236] The /pollResponse/from/acknowledge (string minOccurs=0 maxOccurs=1) field contains information related to acknowledging the alert, while /pollResponse/from/category (minOccurs=0 maxOccurs=1) and /pollResponse/from/category/@id (string minOccurs=0 maxOccurs=1) contains category information.

[0237] The /pollResponse/to (minOccurs=0 maxOccurs=1) tag contains the data pertaining to the receiver. This data can be set by the sender or by any processing/routing agent between the sender and the receiver. The /pollResponse/to/originalUser (minOccurs=0 maxOccurs=1) element defines the original receiver of the alert. A routing agent may change (forward or fan out) an alert to other receivers. If so, it should add this element to the alert.

[0238] The /pollResponse/contents (minOccurs=1 maxOccurs=1) element contains the problem domain-specific data to be conveyed to the receiver. Each child element of the contents element is an argot, a problem domain-specific strongly-typed XML blob. Streams and connections query against the element names of these blobs when selecting alerts they will process. The /pollResponse/contents/{any} (minOccurs=0 maxOccurs=unbounded) contains the argot data.

[0239] The /pollResponse/routing (minOccurs=1 maxOccurs=1) tag contains any routing data inserted by the myAlerts routing process. The /pollResponse/routing/timestamp (string minOccurs=0 maxOccurs=1) element contains the timestamp of when the alert was received by the myAlerts service. The /pollResponse/routing/hops (string minOccurs=0 maxOccurs=1) element defines the actors that have processed the alert to date. This data can be used by the myAlerts service to recognize and stop infinite loops.

[0240] The myAlerts/humanReadable Notification Argot (the humanReadable argot) defines the standard XML schema to convey alert data that should be displayed to human beings to the userAgents:

[0241]

<m:humanReadable
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:baseUrl>1..1</m:baseUrl>
	<m:actionUrl>1..1</m:actionUrl>
	<m:subscriptionUrl>1..1</m:subscriptionUrl>
	<m:language xml:lang=“...” iconUrl=“...”>1..unbounded
	<m:text>1..1</m:text>
	</m:language>
</m:humanReadable>

[0242] The /humanReadable (minOccurs=1 maxOccurs=1) element is an argot used to convey human readable information in an alert. The receiver of a human readable alert should be able, at a minimum, to display the text element data to a human in either textual or speech form. The /humanReadable/baseUrl (anyURI minOccurs=1 maxOccurs=1) comprises a base URL to which all other URLs are relative.

[0243] The /humanReadable/actionUrl (anyURI minOccurs=1 maxOccurs=1) comprises a URL that links to an action page from the sender. This URL can be relative to the baseURL element. The /humanReadable/subscriptionUrl (anyURI minOccurs=1 maxOccurs=1) comprises a URL that links to the sender's page to allow the receiver to view and change the way the alert was sent. This URL can be relative to the baseURL element.

[0244] The /humanReadable/language (minOccurs=1 maxOccurs=unbounded) element contains text specific to a language. As many language elements as desired can be included to convey the same information in different languages. The /humanReadable/language/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /humanReadable/language/@iconUrl (anyURI minOccurs=0 maxOccurs=1) attribute contains an optional URL from the sender for an icon in a Portable Network Graphics (PNG) file that can be used when the userAgent displays the content to the user. The /humanReadable/language/text (string minOccurs=1 maxOccurs=1) element contains the text to be conveyed to the human. This text is in the language specified by the xml:lang attribute.

[0245] The myAlerts/bufferStreamParameters provisioning argot (the bufferStreamParameters argot) defines the data returned by a query from a streamBuffer:

[0246]

<m:bufferStreamParameters
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:notification id=“...”>0..unbounded
	<m:from>1..1
	<m:identityHeader type=“...”>0..1
	<m:onBehalfOfUser>1..1</m:onBehalfOfUser>
	<m:licenseHolder>1..1</m:licenseHolder>
	<m:platformId>1..1</m:platformId>
	</m:identityHeader>
	<m:expiresAt ttl=“...” onDate=“...” replace=“...”>0..1</m:expiresAt>
	<m:acknowledge>0..1</m:acknowledge>
	<m:category id=“...”>0..1</m:category>
	</m:from>
	<m:to>0..1
	<m:originalUser>0..1</m:originalUser>
	</m:to>
	<m:contents>1..1{any}</m:contents>
	<m:routing>1..1
	<m:timestamp>0..1</m:timestamp>
	<m:hops>0..1</m:hops>
	</m:routing>
	</m:notification>
</m:bufferStreamParameters>

[0247] The /bufferStreamParameters (minOccurs=1 maxOccurs=1) element comprises an argot specifying the read and write parameters for a bufferStream stream. For one current implementation of .NET My Services, the bufferStream takes no input parameters; it returns the current set of buffered alerts through this argot. A query on a bufferStream is a transient, read-only operation. The /bufferStreamParameters/notification (minOccurs=0 maxOccurs=unbounded) is directed to zero or more alerts in the buffer of the streamBuffer stream.

[0248] The /bufferStreamParameters/notification (minOccurs=0 maxOccurs=1) comprises a new alert contained in the buffer stream. The /bufferStreamParameters/notification/@id (string minOccurs=0 maxOccurs=1) contains an identifier The /bufferStreamParameters/notification/from (minOccurs=1 maxOccurs=1) tag contains data from the sender, including sender authentication as well as preferences and requests from the sender. The /bufferStreamParameters/from/identityHeader (minOccurs=0 maxOccurs=1) includes /bufferStreamParameters/from/identityHeader/@type (string minOccurs=0 maxOccurs=1) and /bufferStreamParameters/from/identityHeader/onBehalfOfUser (minOccurs=1 maxOccurs=1). The uuidType is used to specify a universally unique identifier (UUID). The /bufferStreamParameters/from/identityHeader/licenseHolder (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID).

[0249] The /bufferStreamParameters/from/identityHeader/platformId (minOccurs=1 maxOccurs=1) uuidType is used to specify a universally unique identifier (UUID). The /bufferStreamParameters/from/expiresAt (string minOccurs=0 maxOccurs=1) is directed to expiration time of an alert, including /bufferStreamParameters/from/expiresAt/@ttl (string minOccurs=0 maxOccurs=1), /bufferStreamParameters/from/expiresAt/@onDate (string minOccurs=0 maxOccurs=1) and /bufferStreamParameters/from/expiresAt/@replace (string minOccurs=0 maxOccurs=1).

[0250] The /bufferStreamParameters/from/acknowledge (string minOccurs=0 maxOccurs=1) field contains information related to acknowledging the alert, while /bufferStreamParameters/from/category (minOccurs=0 maxOccurs=1) and /bufferStreamParameters/from/category/@id (string minOccurs=0 maxOccurs=1) contains category information.

[0251] The /bufferStreamParameters/to (minOccurs=0 maxOccurs=1) tag contains the data pertaining to the receiver. This data can be set by the sender or by any processing/routing agent between the sender and the receiver. The /bufferStreamParameters/to/originalUser (minOccurs=0 maxOccurs=1) element defines the original receiver of the alert. A routing agent may change (forward or fan out) an alert to other receivers. If so, it should add this element to the alert.

[0252] The /bufferStreamParameters/contents (minOccurs=1 maxOccurs=1) element contains the problem domain-specific data to be conveyed to the receiver. Each child element of the contents element is an argot, a problem domain-specific strongly-typed XML blob. Streams and connections query against the element names of these blobs when selecting alerts they will process. The /bufferStreamParameters/contents/{any} (minOccurs=0 maxOccurs=unbounded) contains the argot data.

[0253] The /bufferStreamParameters/routing (minOccurs=1 maxOccurs=1) tag contains any routing data inserted by the myAlerts routing process. The /bufferStreamParameters/routing/timestamp (string minOccurs=0 maxOccurs=1) element contains the timestamp of when the alert was received by the myAlerts service. The /bufferStreamParameters/routing/hops (string minOccurs=0 maxOccurs=1) element defines the actors that have processed the alert to date. This data can be used by the myAlerts service to recognize and stop infinite loops.

[0254] The myAlerts/pushConnectionParameters Provisioning Argot (pushConnectionParameters argot) defines the data passed to and returned from connectionPush:

[0255]

<m:pushConnectionParameters
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myAlerts”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:targetUrl>1..1</m:targetUrl>
</m:pushConnectionParameters>

[0256] The /pushConnectionParameters (minOccurs=1 maxOccurs=1) element comprises an argot specifying the read and write parameters for a connectionPush connection. The /pushConnectionParameters/targetUrl (string minOccurs=1 maxOccurs=1) contains a target URL; the push connection will issue notifyRequest packets to this target URL.

myApplicationSettings

[0257] The myApplicationSettings service 302 is designed to store application settings for applications and for groups of applications. The service is structured around the applicationSetting element. This element is a .NET My Services blue item, as described above, meaning that it may be cached and replicated using standard .NET My Services caching and replication techniques. This element is designed to store and manage a categorized set of named application settings. Categorization is done using standard .NET My Services categorization. The applicationSettings are named using the name element which is a URI. An applicationSetting may have multiple names meaning that the setting is used by a number of applications. The settings themselves are represented using free-form, namespace qualified XML. For example, a setting might look something like in the following table:

[0258]

<m:applicationSetting
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myApplicationSettings”
	>
	<m:name>http://schemas.microsoft.com/hs/2001/10/sdkSamples/xslcal</m:name>
	<!--
	//
	// xcal settings
	//
	-->
	<xcal:settings
	xmlns:xcal=“http://schemas.microsoft.com/hs/2001/10/sdkSamples/xslcal”
	>
	<xcal:initialPuid>6108</xcal:initialPuid>
	<xcal:defaultView>weekView</xcal:defaultView>
	</xcal:settings>
</m:applicationSetting>

[0259] It is expected that applications will use names in either the uuid: URI scheme, or a hierarchical and distributed management scheme like http:.

myApplicationSettings/Roles

[0260] The myApplicationSettings service controls access by using the roleTemplates, rt0, rt1, rt2, rt3, and rt99, using the following scopes:

[0261]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>
	<hs:shape base=t>
	</hs:shape>
</hs:scope>
scope onlySelfElements
<hs:scope id=a159c93d-4010-4460-bc34-5094c49c1633>
	<hs:shape base=nil>
	<hs:include select=//*[@creator=‘$callerId’]/>
	</hs:shape>
</hs: scope>
scope onlySelfSubscriptionElements
<hs:scope id=b7f05a6d-75cd-4958-9dfb-f532ebb17743>
	<hs:shape base=nil>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlyPublicElements
<hs:scope id=da025540-a0c0-470f-adcf-9m7e5a5ec8f>
	<hs:shape base=nil>
	<hs:include select=//* [cat/@ref=‘hs:public’]/>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0262] The myApplicationSettings roleTemplate rt0 role gives give complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myApplicationSettings service through that method while mapped to this roleTemplate.

[0263]

TABLE
myApplicationSettings roleTemplate rt0
	method	scope/name
	query	allElements
	insert	allElements
	replace	allElements
	delete	allElements
	update	allElements

[0264] The myApplicationSettings roleTemplate rtl role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. Applications may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myApplicationSettings service through that method while mapped to this roleTemplate:

[0265]

TABLE
myApplicationSettings roleTemplate rt1
	method	scope/name
	Query	allElements
	Insert	onlySelfElements
	Replace	onlySelfElements
	Delete	onlySelfElements

[0266] The myApplicationSettings roleTemplate rt2 gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myApplicationSettings service through that method while mapped to this roleTemplate.

[0267]

TABLE
myApplicationSettings roleTemplate rt2
	method	scope/name
	query	allElements
	insert	onlySelfSubscriptionElements
	replace	onlySelfSubscriptionElements
	delete	onlySelfsubscriptionElements

[0268] The myApplicationSettings roleTemplate rt3 gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myApplicationSettings service through that method while mapped to this roleTemplate:

[0269]

TABLE
myApplicationSettings roleTemplate rt3
	method	scope/name
	query	onlyPublicElements

[0270] The myApplicationSettings roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99. The following table illustrates that there are no available methods and the scope in effect when accessing the myApplicationSettings service through that method while mapped to this roleTemplate (note that in other services described herein, such an empty table will not be repeated):

[0271]

TABLE
myApplicationSettings roleTemplate rt99
	method	scope/name

myApplicationSettings/Content

[0272] The content document is an identity centric document, with its content and meaning being a function of the puid used to address the service. Accessing the content document is controlled by the associated roleList document. This schema outline in the following table illustrates the layout and meaning of the information found in the content document for the myApplicationSettings service:

[0273]

<m:myApplicationSettings changeNumber=“...” instanceId=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myApplicationSettings”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:applicationSetting changeNumber=“...” id=“...” creator=“...”>0..unbounded
	<m:cat ref=“...”>0..unbounded</m:cat>
	<m:name>0..unbounded</m:name>
	{any}
	</m:applicationSetting>
	<m:subscription changeNumber=“...”id=“..” creator=“...”>0..unbounded
	<hs:trigger select=“...” mode=“...” baseChangeNumber=“...”>1..1</hs:trigger>
	<hs:expiresAt>0..1</hs:expiresAt>
	<hs:context uri=“...”>1..1{any}</hs:context>
	<hs:to>1..1</hs:to>
	</m:subscription>
	{any}
</m:myApplicationSettings>

[0274] The meaning of the attributes and elements shown in the table are set forth below, wherein in the syntax used in the table, boldface type corresponds to a blue node, and underlined type to a red node, as described above, and the minimum occurrence information (0, 1) indicates whether an element or attribute is required or optional, and maximum occurrence information (1, unbounded) indicates whether one or many are possible.

[0275] The /myApplicationSettings (minOccurs=1 maxOccurs=1) element encapsulates the content document for the service. The service is designed to store and manage application settings that are described via well formed, namespace qualified XML. The /myApplicationSettings/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored, e.g., without an error being generated.

[0276] The /myApplicationSettings/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a user is provisioned for a particular service. The /myApplicationSettings/applicationSetting (minOccurs=0 maxOccurs=unbounded) element defines the basic unit of storage within this service which is the applicationSetting. An applicationSetting is cacheable and replicable through normal .NET My Services caching and replication techniques. An applicationSetting is identified by a single and stable id (the @id) attribute. An applicationSetting may also be known by a number of applicationSettingNames which are defined as URIs. The substance part of an application setting is represented by an {any} entry, which essentially is a shorthand notation for any, free-form, namespace qualified XML.

[0277] The /myApplicationSettings/applicationSetting/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0278] The myApplicationSettings/applicationSetting/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored. The /myApplicationSettings/applicationSetting/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0279] The /myApplicationSettings/applicationSetting/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid. The /myApplicationSettings/applicationSetting/cat/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined in the myCategories section of the present application, described below.

[0280] The /myApplicationSettings/applicationSetting/name (anyURI minOccurs=0 maxOccurs=unbounded) element defines a unique name for the applicationSetting that programmers will code to. It is a stable name defined by the applications vs. the @id attribute which is a stable and unique name defined by .NET My Services. The format of this name is a URI. It is expected that applications will name their applicationSettings using URIs with the uuid: scheme, or an http: scheme which allows a delegated hierarchical namespace, e.g.,

[0281] uuid:56c3da65-a6d6-4f78-bbbd-e8c5eac98aae. The http://schemas.microsoft.com/office/2002/08/outlook#coolTools http://schemas.microsoft.com/vs/2002/03/studio#codeLayout element may be repeated any number of times to indicate that this applicationSetting is used by a number of applications.

[0282] The /myApplicationSettings/applicationSetting/{any} (minOccurs=0 maxOccurs=unbounded) field allows the schema to be extended to specify other types of application setting-related data.

[0283] The subscription elements and attributes are common to other services, and are described above.

myCalendar

[0284] The .NET Calendar service, alternatively referred to herein as myCalendar 303, provides calendars for users. This particular service uses an XML schema to describe a typical calendar, a user's calendar store, and the methods by which calendar data is sent and received from the store.

[0285] The .NET Calendar service stores and manages the scheduling of individual and group events and appointments that are associated with an identity. This service supplies scheduling information on demand to other .NET My Services, applications, and devices. .NET Calendar can be used for regular scheduling or group collaboration. Group collaborative features include meeting delegates and role-based access to another identity's calendar.

[0286] The .NET Calendar service is designed to work with the .NET Alerts service to perform reminder alerts and meeting acceptance/decline alerts, with .NET Contacts for service distribution lists, and with .NET Inbox to send and retrieve meeting requests. .NET Inbox will forward meeting invitations to be direct booked (tentative) on attendee calendars which have the correct permissions for this behavior and will forward meeting responses that attendees send back to the organizer to update the organizer's calendar.

[0287] .NET Calendar will support calendar publishing. This feature that allows users to open their calendars to other users such as friends, family members, and group lists. The .NET Calendar service uses .NET My Services to support a rich sharing model based upon the access control list, role map, and identity header.

[0288] The .NET Calendar schema format improves established existing calendar properties and standards. In addition, .NET Calendar establishes a platform for non-Gregorian calendars and additional features such as traveling time allowances for meetings. The schema is designed to be extensible to accommodate new calendar properties or additional recurrence patterns.

myCalendar/Roles

[0289] The myCalendar service controls access by using the rt0, rt1, rt2, rt3 and rt99 roleTemplates, using the following scopes:

[0290]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>

	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0291] The myCalendar roleTemplate rt0 role gives complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myCalendar service through that method while mapped to this roleTemplate:

[0292]

TABLE
myCalendar roleTemplate rt0
	method	scope/name
	query	allElements
	insert	allElements
	replace	allElements
	delete	allElements
	pdate	allElements
	getCalendarDays	allElements
	getFreeBusyDays	allElements
	getQuickView	allElements
	sendMeeting	allElements
	respond	allElements
	updateReminder	allElements

[0293] The myCalendar roleTemplate rtl role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. They may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myCalendar service through that method while mapped to this roleTemplate:

[0294]

TABLE
myCalendar roleTemplate rt1
	method	scope/name
	query	allElements
	insert	onlySelfElements
	replace	onlySelfElements
	delete	onlySelfElements
	sendMeeting	onlySelfElements
	respond	onlySelfElements

[0295] The myCalendar roleTemplate rt2 role gives complete read access to the information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myCalendar service through that method while mapped to this roleTemplate:

[0296]

TABLE
myCalendar roleTemplate rt2
	method	scope/name
	query	allElements
	insert	onlySelfSubscriptionElements
	replace	onlySelfSubscriptionElements
	delete	onlySelfSubscriptionElements
	getCalendarDays	allElements
	getFreeBusyDays	allElements
	getQuickView	allElements

[0297] The myCalendar roleTemplate rt3 role gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myCalendar service through that method while mapped to this roleTemplate:

[0298]

TABLE
myCalendar roleTemplate rt3
	method	scope/name
	query	onlyPublicElements
	getCalendarDays	onlyPublicElements
	getFreeBusyDays	onlyPublicElements
	getQuickView	onlyPublicElements

[0299] The myCalendar roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99.

myCalendar/Content

[0300] The content document is an identity centric document, with its content and meaning a function of the user identifier (puid) used to address the service. Accessing the document is controlled by the associated roleList document. The following table comprises a schema outline that illustrates the layout and meaning of the information found in the content document for the myCalendar service:

[0302] The meaning of the attributes and elements shown in the table are set forth below, wherein in the syntax used in the table, boldface type corresponds to a blue node, and underlined type to a red node, as described above, and the minimum occurrence information (0, 1) indicates whether an element or attribute is required or optional, and maximum occurrence information (1, unbounded) indicates whether one or many are possible.

[0303] The /myCalendar (minOccurs=1 maxOccurs=1) element encapsulates the content document for this service. This element establishes a global cache scope for the service and contains other root level system attributes for this instance of the service. The /myCalendar/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored. The /myCalendar/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a particular service is provisioned for a user.

[0304] The /myCalendar/event (minOccurs=0 maxOccurs=unbounded) event is the myCalendar root object for calendar events, appointments, and meetings.

[0305] The /myCalendar/event/@calendarType (string minOccurs=0 maxOccurs=1) field identifies an enumeration which determines the kind of calendar event this is.

[0306]

[0307] The /myCalendar/event/@advanceHijriValue (int minOccurs=0 maxOccurs=1) field is required for Hijri calendar support. @advanceHijriValue ranges from {−3, −2, −1, 1, 2, 3} and is added to the current date, but the day of the week stays the same. For example, if today is the 24th and @advanceHijriValue is set to be +2, then the user sees the date as being the 26th. Typically @advanceHijriValue is +/−1, and this suffices in most cases. Theoretically it can be any number, but the worst case scenario is +/−3.

[0308] The /myCalendar/event/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0309] The /myCalendar/event/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0310] The /myCalendar/event/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0311] The /myCalendar/event/body (minOccurs=1 maxOccurs=1) includes the /myCalendar/event/body/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute, which is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0312] The /myCalendar/event/body/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing either a global category definition (in either the .NET Categories service system document or an external resource containing category definitions), or by referencing an identity-centered category definition in the content document of the .NET Categories service for a particular PUID.

[0313] The /myCalendar/event/body/cat/@ref (anyURI minOccurs=1 maxOccurs=1) attribute references a category definition (catDef) element using the rules outlined in the .NET Categories section, described above.

[0314] The /myCalendar/event/body/title (string minOccurs=1 maxOccurs=1) includes the /myCalendar/event/body/title/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/body/title/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0315] The /myCalendar/event/body/fullDescription (string minOccurs=0 maxOccurs=1) element contains a free form, full description of the event. The /myCalendar/event/body/fullDescription/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/body/fullDescription/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0316] The /myCalendar/event/body/location (string minOccurs=0 maxOccurs=1) optional element contains the event's location. The /myCalendar/event/body/location/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/body/location/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0317] The /myCalendar/event/body/meetingStatus (string minOccurs=0 maxOccurs=1) tracks the status of this meeting {not-sent, sent, cancelled}. A regular appointment will not have this element. If <meetingStatus> exists, this event should be rendered as a meeting, not as an appointment.

[0318] The /myCalendar/event/body/recurrenceId (dateTime minOccurs=0 maxOccurs=1) recurrence id indicates the original start time of an occurrence of a recurring master appointment. It is required to identify what instance an exception is modifying, since users are allowed to change the start time on an orphan, (wherein an an exception is a modification of an instance and an orphan is an exception that is sent as a meeting request on its own). The recurrenceId method is stored in UTC. It does not appear in the master schema, except in the specific case that an attendee is invited to an instance of a recurring event. Otherwise, <recurrenceId> is usually only a part of getCalendarDays.

[0319] The /myCalendar/event/body/lastUpdateTime (dateTime minOccurs=0 maxOccurs=1) field is updated by the organizer whenever s/he creates and sends a new meeting request. This helps the attendee to identify which meeting request is the most recent one. It is stored in coordinated universal time (UTC). This property is not modifiable by clients and is assigned by the server on modification and by the sendMeetingRequest.

[0320] The /myCalendar/event/body/startTime (dateTime minOccurs=1 maxOccurs=1) startTime method defines the start time of the event. An all-day event by convention starts at 12:00:00 AM of the day of the event. This is stored in UTC. Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. If this event is a recurring event, <startTime> defines the dateTime when the recurrence window starts. The recurring master does not have to be an instance of the recurring event itself. An event in March set to recur every April will only appear in April.

[0321] The /myCalendar/event/body/endTime (dateTime minOccurs=1 maxOccurs=1) endTime method defines the end time of the event. An all-day event by convention ends at 11:59:59 PM of the ending day. This is stored in UTC. Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. The duration of the event is inferred from endTime-startTime.

[0322] The /myCalendar/event/body/allDay (boolean minOccurs=0 maxOccurs=1) element indicates a regular event by being false or being absent. Otherwise, this attribute indicates that the event is an all-day event. All day events may span multiple days. By convention, all day events start at 12:00:00 am of the day of startTime, regardless of what time it actually is, and it will end at 11:59:59 pm of the endTime date. In other words, if the allDay element is present and has value=true, .NET Calendar will ignore the actual times of the events and consider only the date part of the field.

[0323] The allDay tag is meant to operate as a hint to UI renders to display specialized icons indicating an all-day event. allDay events are distinguishable between 24-hr events starting at 12 am. In the case of a meeting request, an allDay event will not appear in the local user's time zone, but rather in the organizer's time zone.

[0324] The /myCalendar/event/body/floating (boolean minOccurs=0 maxOccurs=1) floating attribute indicates that this event is to occur in the current local time zone no matter what time zone the system is currently in (that is, it floats). For example, holidays are floating events. As another example, it may be useful to schedule medication regardless of an actual time zone, whereby a floating attribute is used with such an event. Floating values are stored as-is: no time-zone translations are needed to convert them to UTC or any local time zone.

[0325] The /myCalendar/event/body/travelTimeTo (int minOccurs=0 maxOccurs=1) field contains the amount of time (in minutes) that it takes to travel to the meeting location. The /myCalendar/event/body/travelTimeFrom (int minOccurs=0 maxOccurs=1) field contains the amount of time (in minutes) that it takes to return from the meeting location. These optional elements show in free/busy calculations.

[0326] The /myCalendar/event/body/freeBusyStatus (string minOccurs=0 maxOccurs=1) optional element annotates the freeBusy behavior of this event. Events by default appear as “busy”. The user may explicitly define this event to be annotated by setting .NET Calendar values to free, tentative, busy or away.

[0327] The /myCalendar/event/body/cuid (string minOccurs=0 maxOccurs=1) cuid (CorrelationUID) links an organizer's event to an attendee's event. It identifies which response from an attendee is for which request from an organizer, and which meeting request update from the organizer is for which previously accepted meeting by the attendee. The “cuid” is the same on both the attendee's and the organizer's copy of the appointment. It is also identical on the exception and the recurring master, wherein an exception is a modification of an instance. This value is assigned by the .NET Calendar server and is non-modifiable.

[0328] The /myCalendar/event/body/organizer (minOccurs=0 maxOccurs=1) field contains the email address of the event organizer. The /myCalendar/event/body/organizer/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/body/organizer/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/body/organizer/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0329] The /myCalendar/event/body/organizer/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /myCalendar/event/body/organizer/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element.

[0330] The /myCalendar/event/body/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional body elements.

[0331] The /myCalendar/event/attendeeEventExtra (minOccurs=0 maxOccurs=1) field contains additional information about an event, found only in an event invitee's schema. The /myCalendar/event/attendeeEventExtra/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0332] The /myCalendar/event/attendeeEventExtra/intendedFreeBusy (string minOccurs=0 maxOccurs=1) element is the event organizer's freeBusy information and is thus equal to event/freeBusyStatus. Invitees may overwrite event/freeBusyStatus with a new value, and intendedFreeBusy is intended to store the organizer's original freeBusyStatus.

[0333] The /myCalendar/event/attendeeEventExtra/responseTime (dateTime minOccurs=0 maxOccurs=1) field contains the reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what is maintained in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0334] The /myCalendar/event/attendeeEventExtra/responseType (string minOccurs=0 maxOccurs=1) accept status indicates the valid types of responses that an attendee can reply with {accept, decline, tentative, counterpropose}. The absence of this field indicates that no response has been recorded.

[0335] The /myCalendar/event/attendeeEventExtra/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the startTime, endTime, or location, or all three can be present. This is the invitee's counterproposal for a new start time for the meeting. This is stored in UTC.

[0336] The /myCalendar/event/attendeeEventExtra/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterProposal for a new end time for the meeting. This is stored in UTC.

[0337] The /myCalendar/event/attendeeEventExtra/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information. field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterProposal for a location for the meeting.

[0338] The /myCalendar/event/attendeeEventExtra/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /myCalendar/event/attendeeEventExtra/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/attendeeEventExtra/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0339] The /myCalendar/event/attendeeEventExtra/delegateResponder (minOccurs=0 maxOccurs=1) field stores information of a delegate who responds on behalf of an invitee. The /myCalendar/event/attendeeEventExtra/delegateResponder/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/attendeeEventExtra/delegateResponder/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/attendeeEventExtra/delegateResponder/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0340] The /myCalendar/event/attendeeEventExtra/delegateResponder/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /myCalendar/event/attendeeEventExtra/delegateResponder/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /myCalendar/event/attendeeEventExtra/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional attendee extra properties.

[0341] The /myCalendar/event/attachment (minOccurs=0 maxOccurs=unbounded) element contains attachment metadata, name, content-type and id's, and may also contain the attachmentBody. The /myCalendar/event/attachment/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0342] The /myCalendar/event/attachment/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0343] The /myCalendar/event/attachment/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myCalendar/event/attachment/name (string minOccurs=1 maxOccurs=1) element contains information about an individual attachment in a mail message. The /myCalendar/event/attachment/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/attachment/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0344] The /myCalendar/event/attachment/contentType (string minOccurs=1 maxOccurs=1) element contains the content type of the attachment. The /myCalendar/event/attachment/contentTransferEncoding (string minOccurs=1 maxOccurs=1) element contains the encoding of the attachment. This information is necessary for decoding the attachment. The /myCalendar/event/attachment/size (unsignedLong minOccurs=1 maxOccurs=1) element contains the size of the attachment in bytes. The /myCalendar/event/attachment/attachmentBody (base64Binary minOccurs=1 maxOccurs=1) element contains the contents of the attachment.

[0345] The /myCalendar/event/reminder (minOccurs=0 maxOccurs=1) is directed to reminders. A user may optionally define a reminder for this appointment. Reminders for recurring appointments will be sent periodically before the appointment, as per the rules defined in the reminder subschema below. A non-recurring event may define no reminders, define a reminder with <set>=“true” or define a reminder with <set>=“false”.

[0346] A recurring meeting may have no reminders defined, or a recurring reminder defined with all instances receiving reminders. To define no reminders by default, but to define reminders for particular meeting instances in the exception body, a reminder <set>=“false” is created, and turned on and/or modified for particular instances. To define a recurring reminder, but turn it off for particular meeting instances, a reminder <set>=“true” is created, and turned off for particular instances.

[0347] If the event's reminder subschema is non-existent, yet the exception body has a reminder blob, then the exception reminder is ignored. An alternative is to require this.

[0348] The /myCalendar/event/reminder/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0349] The /myCalendar/event/reminder/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0350] The /myCalendar/event/reminder/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myCalendar/event/reminder/set (boolean minOccurs=1 maxOccurs=1) field maintains a Boolean flag that indicates whether the reminder is active for this event. In most cases, this will be true, but in the case of a recurring appointment, this flag may default to true with specific instances not to be reminded, or default to false, with specific instances to be reminded.

[0351] The /myCalendar/event/reminder/to (string minOccurs=1 maxOccurs=1) stores a friendly name that this reminder is being sent to. The /myCalendar/event/reminder/to/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/reminder/to/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0352] The /myCalendar/event/reminder/offset (int minOccurs=1 maxOccurs=1) field specifies the offset, in minutes, of how long before the event the user should be reminded. Recommended values are set forth in the following table:

[0353]

Value	Description
5, 10, 20, 30, 45	5, 10, 20, 30, 45 minutes before the event
60, 120, 180,	1, 2, 3 hours before the event
startTime − startDay	The day of the event (reminder sent
	at 12:00 am)
startTime − (startDay −	“x” days before the event (reminder sent at
(1440 * x))	12:00 am “x” days before)

[0354] The /myCalendar/event/reminder/interruptability (int minOccurs=0 maxOccurs=1) optional element defines how interruptible this event is and it is used by notification routing software to make decisions about the relay and deferral of notifications that might occur while this meeting is active. The value contained in this element is a numeric value between one and ten. Low values represent a high cost of disruption, high values represent a low cost of disruption.

[0355] The /myCalendar/event/reminder/lastSentTime (dateTime minOccurs=1 maxOccurs=1) field is required by the reminder engine. The /myCalendar/event/reminder/nextTriggerTime (dateTime minOccurs=1 maxOccurs=1) determines the next time to trigger reminder.

[0356] The /myCalendar/event/attendee (minOccurs=0 maxOccurs=unbounded) includes the attendeeType, which contains the information about an attendee, including the display, email, puid, and the attendee's response.

[0357] The /myCalendar/event/attendee/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0358] The /myCalendar/event/attendee/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0359] The /myCalendar/event/attendee/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myCalendar/event/attendee/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/attendee/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/attendee/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0360] The /myCalendar/event/attendee/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /myCalendar/event/attendee/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /myCalendar/event/attendee/inviteType (string minOccurs=1 maxOccurs=1) is used by a meeting organizer to define the kind of invitee, e.g., as required, optional, or a resource (e.g., meeting room).

[0361] The /myCalendar/event/attendee/responseTime (dateTime minOccurs=0 maxOccurs=1) reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what s/he maintains in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0362] The /myCalendar/event/attendee/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new start time for the meeting. This is stored in UTC.

[0363] The /myCalendar/event/attendee/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new end time for the meeting. This is stored in UTC.

[0364] The /myCalendar/event/attendee/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information, field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a location for the meeting.

[0365] The /myCalendar/event/attendee/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /myCalendar/event/attendee/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/attendee/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0366] The /myCalendar/event/attendee/{any} (minOccurs=0 maxOccurs=unbounded) allows for extensibility.

[0367] The /myCalendar/event/recurrence (minOccurs=0 maxOccurs=1) includes /myCalendar/event/recurrence/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute, designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0368] The /myCalendar/event/recurrence/rule (minOccurs=1 maxOccurs=1) includes the /myCalendar/event/recurrence/rule/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute, designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0369] The /myCalendar/event/recurrence/rule/creationDate (dateTime minOccurs=1 maxOccurs=1) is required in order to exactly determine which timezone recurrence rule to use. The startTime of the event is not used because of the ability to create events in the past and in the future.

[0370] The /myCalendar/event/recurrence/rule/firstDayOfWeek (string minOccurs=1 maxOccurs=1) stores what the first day of the week (DOW) is for this user. Typical values are (su) Sunday or (mo) Monday. This maintains a recurrence rule's specified FirstDOW (for calculating the recurrence expansion. Allows recurring meetings to be expanded in the organizer's FirstDOW instead of the invitee's FirstDOW.

[0371] The /myCalendar/event/recurrence/rule/tzid (int minOccurs=0 maxOccurs=1) identifies the time zone for this recurring event. The dateTime information in this event is stored in UTC (converted from the local time zone defined by the time zone sub-schema). If this field is absent, the recurring event is assumed to be recurring in UTC time. However, it is only a floating recurring event if the <floating> attribute is set, as described above. @afterDay is currently used, but is optional.

[0372] The /myCalendar/event/recurrence/rule/isLeapYear (boolean minOccurs=0 maxOccurs=1) provides International calendar support. It is possible to derive isLeapYear from leapMonthValue, but .NET Calendar stores both separately. The /myCalendar/event/recurrence/rule/leapMonthValue (int minOccurs=0 maxOccurs=1) <leapMonthValue> cannot be derived from a particular year and thus must be stored. For example, a user creates a recurrence on a Hebrew Lunar calendar. The year is a leap year and it has 13 months. In that year, the leapMonthValue is 7.

[0373] The /myCalendar/event/recurrence/rule/repeat (minOccurs=1 maxOccurs=1) may includes the /myCalendar/event/recurrence/rule/repeat/daily (minOccurs=0 maxOccurs=1), field, which specifies the number of days to repeat, e.g., repeat every [ . . . ] days. The /myCalendar/event/recurrence/rule/repeat/daily/@dayFrequency (int minOccurs=1 maxOccurs=1) specifies the periodicity of days over which repetition occurs, for example, repeat every 3 days.

[0374] The /myCalendar/event/recurrence/rule/repeat/weekly (minOccurs=0 maxOccurs=1) field, if present, is directed to repeating weekly, e.g., repeat every [ . . . ] week(s) on {su, mo, tu, we, th, fr, sa}. The presence of a weekday attribute means to repeat on this particular day. Any combination of the seven days is valid.

[0375] The /myCalendar/event/recurrence/rule/repeat/weekly/@weekFrequency (int minOccurs=0 maxOccurs=1) repeatWeekly recurrence occurs every period of weeks. If the attribute is not present, it defaults to 1 (every week).

[0376] The /myCalendar/event/recurrence/rule/repeat/monthlyByDay (minOccurs=0 maxOccurs=1) specifies to repeat on the [First, Second, Third, Fourth, Last] {su, mo, tu, we, th, fr, sa} of every [. . . ] month(s). Any combination of the {weekday} attributes are valid, including user-defined combinations for weekdays and weekend days.

[0377] The /myCalendar/event/recurrence/rule/repeat/monthlyByDay/@monthFrequency (int minOccurs=0 maxOccurs=1) specifies the month periodicity to recur on. If this attribute is not present, it defaults to 1 (every month).

[0378] The /myCalendar/event/recurrence/rule/repeat/monthlyByDay/@weekdayOfMonth (string minOccurs=1 maxOccurs=1) specifies which week in a month [first, second, third, fourth, last].

[0379] The /myCalendar/event/recurrence/rule/repeat/monthly (minOccurs=0 maxOccurs=1) repeats the occurrence every month on a particular day. The very first occurrence is created from the parent event's startTime and endTime, but the recurrence occurs as follows: Repeat every month on [day] of [month]. Repeat every [monthFrequency] month(s) on [day] of [month]. Typically, the first occurrence is also an instance of the recurrence, but this need not be the case.

[0380] The /myCalendar/event/recurrence/rule/repeat/monthly/@monthFrequency (int minOccurs=0 maxOccurs=1) optional attribute indicates the month periodicity. By default, it is 1, periodic every month. The start of the periodicity is determined from event startTime. The /myCalendar/event/recurrence/rule/repeat/monthly/@day (int minOccurs=1 maxOccurs=1) specifies the day of the month to recur on. Value is between one and 31.

[0381] A forceExact rule handles invalid day-month combinations. The proper recurrence pattern for repeating on the last day of the month is to use repeatMonthlyByDay. “Repeat on the [last] [day, weekday, weekend day] of . . . ”. By default, an invalid day-month combination will cause .NET Calendar to search backwards to find a valid day-month combination. If /myCalendar/event/recurrence/rule/repeat/monthly/@forceExact (boolean minOccurs=0 maxOccurs=1) is true, an invalid starting [month , day] combination such as [6, 31] is ignored and will not be included as an instance of the recurrence. With forceExact, day=31 will only pick up months that have 31 days, day=30 will pick up all months except February, day-29 will pick up all months except February, except on leap years. February 29 is included on leap years.

[0382] The /myCalendar/event/recurrence/rule/repeat/yearlyByDay (minOccurs=0 maxOccurs=1) specifies how to repeat on the [First, Second, Third, Fourth, Last] {su, mo, tu, we, th, fr, sa} of [Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec] every [yearFrequency] years.

[0383] Any combination of the {weekday} attributes are valid, including user-defined combinations denoting weekdays and weekend days. This element's attributes contain whether a given day is or is not considered by the user as part of the work week. If this element has no attributes, it is assumed that the user has a Monday to Friday work week.

[0384] The /myCalendar/event/recurrence/rule/repeat/yearlyByDay/@yearFrequency (int minOccurs=0 maxOccurs=1) optional attribute indicates the year periodicity. By default, it is 1 (repeat every year).

[0385] The /myCalendar/event/recurrence/rule/repeat/yearlyByDay/@weekdayOfMonth (string minOccurs=1 maxOccurs=1) Specifies which week in a month [first, second, third, fourth, last] to repeat.

[0386] The /myCalendar/event/recurrence/rule/repeat/yearlyByDay/@month (int minOccurs=1 maxOccurs=1) contains a value between one and thirteen (some calendars have thirteen months).

[0387] The /myCalendar/event/recurrence/rule/repeat/yearly (minOccurs=0 maxOccurs=1) specifies to repeat every year on a particular date. The very first occurrence is created from the parent event's startTime and endTime, but the recurrence occurs as follows: Repeat yearly on [day] of [month]. Repeat every [yearFrequency] years on [day] of [month]. Typically, the first occurrence is also an instance of the recurrence, but this need not be the case.

[0388] The /myCalendar/event/recurrence/rule/repeat/yearly/@yearFrequency (int minOccurs=0 maxOccurs=1) optional attribute indicates the year periodicity. By default, it is 1 (repeat every year). The /myCalendar/event/recurrence/rule/repeat/yearly/@month (int minOccurs=1 maxOccurs=1) specifies the month to recur on.

[0389] The /myCalendar/event/recurrence/rule/repeat/yearly/@day (int minOccurs=1 maxOccurs=1) specifies the day of the month to recur on. The value is between 1-31, and forceExact, applies for invalid day-month combinations. Thus, by default, an invalid day-month-year combination will cause .NET Calendar to search backwards to find a valid day for a particular month, year. If /myCalendar/event/recurrence/rule/repeat/yearly/@forceExact (boolean minOccurs=0 maxOccurs=1) is true, an invalid starting [month , day] combination such as [6, 31] is ignored and will not be included as an instance of the recurrence. With forceExact, .NET Calendar, day=31 will only pick up months that have 31 days, day=30 will pick up all months except February, day-29 will pick up all months except February, except on leap years. February 29 is included on leap years.

[0390] The /myCalendar/event/recurrence/rule/repeat/{any} (minOccurs=0 maxOccurs=unbounded) allows for any additional repeat rules.

[0391] The /myCalendar/event/recurrence/rule/windowEnd (dateTime minOccurs=0 maxOccurs=1) field indicates the end of the window over which the recurrence occurs. This is stored in UTC. The Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. Note that windowEnd, repeatForever, repeatInstances may be selectable.

[0392] The /myCalendar/event/recurrence/rule/repeatForever (boolean minOccurs=0 maxOccurs=1) overrides the windowEnd date and specifies that this recurrence repeats forever. Client implementations cannot depend on date values repeating forever, like 23:59:59 pm Dec. 31, 9999 or 23:59 Aug. 31, 4500.

[0393] The /myCalendar/event/recurrence/rule/repeatInstances (int minOccurs=0 maxOccurs=1) overrides the windowEnd date and specifies that this recurrence repeats for the specified number of instances. As is apparent, repeatInstances and repeatForever are mutually exclusive, but repeatInstances will override repeatForever for errant schemas.

[0394] The /myCalendar/event/recurrence/rule/deletedExceptionDate (dateTime minOccurs=0 maxOccurs=unbounded) allows exceptions to a recurrence rule, which are added as an element list of dates. In general, the purpose of deletedExceptionDate is to prevent an instance/occurrence from being generated during expansion of the series. The myCalendar service logic ignores the hh:mm:ss of the dateTime and merely blocks out the particular day. Any days can be added to an exception rule, including days where no occurrences of a recurrence rule would fall in the first place. This is stored in UTC.

[0395] The /myCalendar/event/recurrence/rule/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional recurrence rule logic that cannot be expressed in .NET Calendar logic.

[0396] The /myCalendar/event/recurrence/exception (minOccurs=0 maxOccurs=unbounded) field contains a list of modified event properties for this particular orphan event. The properties that are not modified are inherited from the original event upon recurrence expansion (client-side). A recurrenceId is always present, and is used to determine which instance of the original rule this modifiedException applies to.

[0397] The /myCalendar/event/recurrence/exception/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0398] The /myCalendar/event/recurrence/exception/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0399] The /myCalendar/event/recurrence/exception/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myCalendar/event/recurrence/exception/recurrenceId (dateTime minOccurs=1 maxOccurs=1) field contains the original start time (recurrenceId) of the occurrence that is being modified by this exception. ModifiedExceptions with recurrenceIds that do not match the recurrenceId of any occurrence are ignored. This is stored in UTC. Note that modifiedException does not expose the id attribute; the recurrenceId should be used to predicate instead, as it functions as the id of modifiedException.

[0400] The /myCalendar/event/recurrence/exception/body (minOccurs=0 maxOccurs=1) field contains the modifiable properties of the eventbody. The /myCalendar/event/recurrence/exception/body/title (string minOccurs=0 maxOccurs=1) allows for title changes. The /myCalendar/event/recurrence/exception/body/title/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/body/title/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0401] The /myCalendar/event/recurrence/exception/body/fullDescription (string minOccurs=1 maxOccurs=1) provides for a a revised description. The /myCalendar/event/recurrence/exception/body/fullDescription/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/body/fullDescription/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0402] The /myCalendar/event/recurrence/exception/body/location (string minOccurs=0 maxOccurs=1) allows for a meeting location to be switched, for this instance only (not recurring instances). The /myCalendar/event/recurrence/exception/body/location/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/body/location/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0403] The /myCalendar/event/recurrence/exception/body/startTime (dateTime minOccurs=0 maxOccurs=1), if present, switches the start time, again for this instance only. The /myCalendar/event/recurrence/exception/body/endTime (dateTime minOccurs=0 maxOccurs=1) switches the end time for this instance only.

[0404] The /myCalendar/event/recurrence/exception/body/allDay (boolean minOccurs=0 maxOccurs=1) specifies that this particular instance is allDay. The /myCalendar/event/recurrence/exception/body/travelTimeTo (int minOccurs=0 maxOccurs=1) can adjust the travel to time for this instance, such as if traffic is a problem. The /myCalendar/event/recurrence/exception/body/travelTimeFrom (int minOccurs=0 maxOccurs=1) can adjust the travel from time for this instance.

[0405] The /myCalendar/event/recurrence/exception/body/freeBusyStatus (string minOccurs=0 maxOccurs=1) handles a priority is changed for this meeting instance.

[0406] The /myCalendar/event/recurrence/exception/body/organizer (minOccurs=0 maxOccurs=1) field will be present when the original organizer is replaced by another organizer.

[0407] The /myCalendar/event/recurrence/exception/body/organizer/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/recurrence/exception/body/organizer/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/body/organizer/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0408] The /myCalendar/event/recurrence/exception/body/organizer/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /myCalendar/event/recurrence/exception/body/organizer/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /myCalendar/event/recurrence/exception/attendeeEventExtra (minOccurs=0 maxOccurs=1) provides for additional information about an event, found only in an event invitee's schema.

[0409] The /myCalendar/event/recurrence/exception/attendeeEventExtra/intendedFreeBusy (string minOccurs=0 maxOccurs=1) intendedFreeBusy element is the event organizer's freeBusy information, and is thus equal to event/freeBusyStatus. Invitees may overwrite event/freeBusyStatus with a new value, and intendedFreeBusy is intended to store the organizer's original freeBusyStatus.

[0410] The /myCalendar/event/recurrence/exception/attendeeEventExtra/responseTime (dateTime minOccurs=0 maxOccurs=1) reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what is maintained in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0411] The /myCalendar/event/recurrence/exception/attendeeEventExtra/responseType (string minOccurs=0 maxOccurs=1) accept status indicates the valid types of responses that an attendee can reply with {accept, decline, tentative, counterpropose}. The absence of this field indicates that no response has been recorded.

[0412] The /myCalendar/event/recurrence/exception/attendeeEventExtra/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new start time for the meeting. This is stored in UTC.

[0413] The /myCalendar/event/recurrence/exception/attendeeEventExtra/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee counterProposal for a new end time for the meeting. This is stored in UTC.

[0414] The /myCalendar/event/recurrence/exception/attendeeEventExtra/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information. field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a location for the meeting.

[0415] The /myCalendar/event/recurrence/exception/attendeeEventExtra/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /myCalendar/event/recurrence/exception/attendeeEventExtra/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/attendeeEventExtra/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0416] The /myCalendar/event/recurrence/exception/attendeeEventExtra/delegateResponder (minOccurs=0 maxOccurs=1), when present, is for a delegate who responds on behalf of an invitee; the delegate will have their information stored here.

[0417] The /myCalendar/event/recurrence/exception/attendeeEventExtra/delegateResponder/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/recurrence/exception/attendeeEventExtra/delegateResponder/name/@xml: lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/attendeeEventExtra/delegateResponder/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

The /myCalendar/event/recurrence/exception/attendeeEventExtra/delegateResponder/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /myCalendar/event/recurrence/exception/attendeeEventExtra/{any} (minOccurs=0 maxOccurs=unbounded) allows for additional attendee extra properties.

[0419] The meeting organizer of a recurring meeting may wish to exclude a particular attendee for an instance of the meeting. This idRefType (puid) indicates which attendee, (from the list of attendees at the event level) are not invited to this particular meeting instance, as specified in /myCalendar/event/recurrence/exception/deletedAttendee (string minOccurs=0 maxOccurs=unbounded). The /myCalendar/event/recurrence/exception/deletedAttachment (string minOccurs=0 maxOccurs=unbounded) is used when the meeting organizer of a recurring meeting may wish to exclude a particular attachment for an instance of the meeting.

[0420] The /myCalendar/event/recurrence/exception/attachment (minOccurs=0 maxOccurs=unbounded) specifies the scheme the message contents were encoded in. Examples of this are ‘7 bit’, ‘8 bit’ and ‘base64’.

[0421] The /myCalendar/event/recurrence/exception/attachment/name (string minOccurs=1 maxOccurs=1) element contains information about an individual attachment in a mail message. The /myCalendar/event/recurrence/exception/attachment/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/attachment/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0422] The /myCalendar/event/recurrence/exception/attachment/contentType (string minOccurs=1 maxOccurs=1) element contains the content type of the attachment.

[0423] The /myCalendar/event/recurrence/exception/attachment/contentTransferEncoding (string minOccurs=1 maxOccurs=1) element contains the encoding of the attachment. This information is necessary for decoding the attachment.

[0424] The /myCalendar/event/recurrence/exception/attachment/size (unsignedLong minOccurs=1 maxOccurs=1) element contains the size of the attachment in bytes.

[0425] The /myCalendar/event/recurrence/exception/attachment/attachmentBody (base64Binary minOccurs=1 maxOccurs=1) element contains the contents of the attachment.

[0426] The /myCalendar/event/recurrence/exception/attendee (minOccurs=0 maxOccurs=unbounded) attendeeType contains the information about an attendee, including the display, email, puid, and the attendee's response.

[0427] The /myCalendar/event/recurrence/exception/attendee/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /myCalendar/event/recurrence/exception/attendee/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/attendee/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0428] The /myCalendar/event/recurrence/exception/attendee/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element.

[0429] The /myCalendar/event/recurrence/exception/attendee/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element.

[0430] The /myCalendar/event/recurrence/exception/attendee/inviteType (string minOccurs=1 maxOccurs=1) is used by the meeting organizer to define the kind of invitee {required, optional, resource}.

[0431] The /myCalendar/event/recurrence/exception/attendee/responseTime (dateTime minOccurs=0 maxOccurs=1) is for the reply time. The reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they always update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what s/he maintains in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0432] The /myCalendar/event/recurrence/exception/attendee/responseType (string minOccurs=0 maxOccurs=1) accept status indicates the valid types of responses that an attendee can reply with {accept, decline, tentative, counterpropose}. The absence of this field indicates that no response has been recorded (either the invitation has not been sent, or that a reply has not been received).

[0433] The /myCalendar/event/recurrence/exception/attendee/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) is like other counter proposal data. Thus, If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterProposal for a new start time for the meeting. This is stored in UTC. The /myCalendar/event/recurrence/exception/attendee/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) is for the counter-proposed end time, and if responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterProposal for a new end time for the meeting. This is stored in UTC. The /myCalendar/event/recurrence/exception/attendee/counterProposeLocation (string minOccurs=0 maxOccurs=1) field is for the counter-proposed location. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a location for the meeting.

[0434] The /myCalendar/event/recurrence/exception/attendee/responseBody (string minOccurs=0 maxOccurs=1) provides for an optional message for invitees to include along with the response. The /myCalendar/event/recurrence/exception/attendee/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCalendar/event/recurrence/exception/attendee/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0435] The /myCalendar/event/recurrence/exception/attendee/{any} (minOccurs=0 maxOccurs=unbounded) field provides extensibility.

[0436] The /myCalendar/event/recurrence/exception/reminder (minOccurs=0 maxOccurs=1) are the properties of the reminder that may be modified. If there is no reminder subschema in the event body, exception reminders are ignored.

[0437] The /myCalendar/event/recurrence/exception/reminder/set (boolean minOccurs=0 maxOccurs=1), /myCalendar/event/recurrence/exception/reminder/offset (int minOccurs=0 maxOccurs=1) and /myCalendar/event/recurrence/exception/reminder/interruptability (int minOccurs=0 maxOccurs=1), are generally as described above, however note that these fields are for exceptions.

[0438] The /myCalendar/event/recurrence/exception/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional properties of the myCalendar/BaseEventType schema.

[0439] The /myCalendar/event/recurrence/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional recurrence rule elements.

[0440] The /myCalendar/subscription (minOccurs=0 maxOccurs=unbounded) element defines a subscription node as described above in the subscription section.

myCalendar/Domain Specific Methods

[0441] In addition to the standard methods, the myCalendar service supports the domain-specific methods, getCalendarDays, getFreeBusyDays, getQuickView, sendMeeting, respond and updateReminder.

[0442] The myCalendar/getCalendarDaysRequest is a calendar date range event generator. This method is accessed using a request message, and in response may generate a response message or a SOAP Fault message. The following sample document fragments illustrate the structure and meaning of the elements and attributes in the request and response messages. The following is a request message XML fragment for getCalendarDays; it takes a startDate and an endDate to define the duration over which calendar events are returned:

[0443]

<m:getCalendarDaysRequest
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:calendarType>0..1</m:calendarType>
	<m:startTime>0..1</m:startTime>
	<m:endTime>1..1</m:endTime>
	<m:removeRecurrence>0..1</m:removeRecurrence>
</m:getCalendarDaysRequest>

[0444] The /getCalendarDaysRequest (minOccurs=1 maxOccurs=1) function returns an XML stream of calendar appointments/events between two dates. Recurrence rules are expanded to create individual calendar items. Holidays are represented as all-day events, and these are returned as well. The getCalendarDays method is a query-retrieval of data, but the behavior expands recurrence rules into individual (aliased) events, adds in holidays, and adds regular events and sorts the entire list based on start time. No merging of event blocks occurs. Any object which overlaps the method parameters {startTime, endTime} will be returned. For example, if an event crosses midnight and the startTime is 12 am, that event will be returned. In case the startDate, endDate is one day, the events are sorted in the following order: holidays, all-day events, and regular events (based on startTime). The {startTime, endTime] time window can define any interval: 24 hr period, week, month, or any other user-defined period.

[0445] The getCalendarDays method returns the calendaring info of any puid that is specified for which the caller has sufficient privileges. The user's own puid must be specified to retrieve their own information. The getCalendarDays method may be used to retrieve multiple calendar data from other users using <h:key instance=“0” cluster=“0” puid=“xyz”/> in the SOAP headers provided that puid “xyz” is provisioned on the .NET Calendar server, and provided that the user has been granted access in puid “xyz”'s rolelist.

[0446] The /getCalendarDaysRequest/calendarType (string minOccurs=0 maxOccurs=1) optionally specifies the calendar type to return, as set forth in the calendar-types table above. The system defaults to Gregorian if not specified.

[0447] The /getCalendarDaysRequest/startTime (dateTime minOccurs=1 maxOccurs=1) specifies the starting time window of calendar objects to retrieve. This dateTime also contains the timeZone to retrieve the calendar information in.

[0448] The /getCalendarDaysRequest/endTime (dateTime minOccurs=1 maxOccurs=1) field contains the ending time window to retrieve calendar objects. This dateTime also contains the timeZone to retrieve the calendar information in, and needs to be the same timeZone as startTime.

[0449] Normally, the recurrence sub-schema, (minus modifiedException and minus deletedExceptionDate components) is returned with each instance of a recurring event, like “recurring-instance” and “recurring-exception”. This allows clients to properly render the recurrence pattern without having to explicitly query the recurring-master. However, because it is heavy on bandwidth, .NET Calendar includes the option to not return this data, via /getCalendarDaysRequest/removeRecurrence (boolean minOccurs=0 maxOccurs=1).

[0450] Upon successful completion of the above method, a response message, myCalendar/getCalendarDaysResponse, is generated. In the response, calendar events are returned with their recurrence rules expanded into first-class events. These events have aliased PUIDs, logically as part of the same event. Recurrence information is stripped from the original event. The following is a response schema outline:

[0451]

[0452] The /getCalendarDaysResponse (minOccurs=1 maxOccurs=1) response XML blob format, comprises the base event type minus recurrence. The /getCalendarDaysResponse/@selectedNodeCount (int minOccurs=0 maxOccurs=1) This attribute is used to return the number of selected nodes, selected by the corresponding data language operation. The /getCalendarDaysResponse/@status (string minOccurs=1 maxOccurs=1) attribute indicates the status of the method.

[0453] If the status is success, the corresponding method was completed successfully. If the status is failure, the corresponding method was not completed successfully. If the status is rollback, the method failed, but was rolled back to its pre-updateBlock status. If the status is notAttempted, the corresponding method was not attempted. This occurs when a previous operation failed.

[0454] The /getCalendarDaysResponse/event (minOccurs=0 maxOccurs=unbounded), if present, may have a /getCalendarDaysResponse/event/@instanceType (string minOccurs=0 maxOccurs=1) field which distinguishes between a single instance of an event or an instance of a recurring event. The recurring instance is a modified exception if eventBody/recurrenceId is present: single, recurring-master, recurring-instance, recurring-exception. The /getCalendarDaysResponse/event/@calendarType (string minOccurs=0 maxOccurs=) field identifies an enumeration which determines the kind of calendar event this is, as set forth in the above calendar type table.

[0455] The /getCalendarDaysResponse/event/@advanceHijriValue (int minOccurs=0 maxOccurs=1) field is required for Hijri calendar support. @advanceHijriValue ranges from {−3, −2, −1, 1, 2, 3} and is added to the current date, but the day of the week stays the same. For example, if today is the 24th and @advanceHijriValue is set to be +2, then the user sees the date as being the 26th. Typically @advanceHijriValue is +/−1, and this suffices in most cases. Theoretically it can be any number, but the worst case scenario is +/−3.

[0456] The /getCalendarDaysResponse/event/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0457] The /getCalendarDaysResponse/event/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0458] The /getCalendarDaysResponse/event/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0459] The /getCalendarDaysResponse/event/body (minOccurs=1 maxOccurs=1) includes the /getCalendarDaysResponse/event/body/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute, which is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0460] The /getCalendarDaysResponse/event/body/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing either a global category definition (in either the .NET Categories service system document or an external resource containing category definitions), or by referencing an identity-centered category definition in the content document of the .NET Categories service for a particular PUID).

[0461] The /getCalendarDaysResponse/event/body/cat/@ref (anyURI minOccurs=1 maxOccurs=1) attribute references a category definition (catDef) element using the rules outlined in the .NET Categories section, described above.

[0462] The /getCalendarDaysResponse/event/body/title (string minOccurs=1 maxOccurs=1) includes the /getCalendarDaysResponse/event/body/title/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/body/title/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0463] The /getCalendarDaysResponse/event/body/fullDescription (string minOccurs=0 maxOccurs=1) element contains a free form, full description of the event. The /getCalendarDaysResponse/event/body/fullDescription/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/body/fullDescription/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0464] The /getCalendarDaysResponse/event/body/location (string minOccurs=0 maxOccurs=1) optional element contains the event's location. The /getCalendarDaysResponse/event/body/location/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/body/location/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0465] The /getCalendarDaysResponse/event/body/meetingStatus (string minOccurs=0 maxOccurs=1) tracks the status of this meeting {not-sent, sent, cancelled}. A regular appointment will not have this element. If <meetingStatus> exists, this event should be rendered as a meeting, not as an appointment.

[0466] The /getCalendarDaysResponse/event/body/recurrenceId (dateTime minOccurs=0 maxOccurs=1) recurrence id indicates the original start time of an occurrence of a recurring master appointment. It is required to identify what instance an exception is modifying, since users are allowed to change the start time on the orphan. The recurrenceId method is stored in UTC. It does not appear in the master schema, except in the specific case that an attendee is invited to an instance of a recurring event. Otherwise, <recurrenceId> is usually only a part of getCalendarDays.

[0467] The /getCalendarDaysResponse/event/body/lastUpdateTime (dateTime minOccurs=0 maxOccurs=1) field is updated by the organizer whenever s/he creates and sends a new meeting request. This helps the attendee to identify which meeting request is the most recent one. It is stored in coordinated universal time (UTC). This property is not modifiable by clients and is assigned by the server on modification and by the sendMeetingRequest.

[0468] The /getCalendarDaysResponse/event/body/startTime (dateTime minOccurs=1 maxOccurs=1) startTime method defines the start time of the event. An all-day event by convention starts at 12:00:00 AM of the day of the event. This is stored in UTC. Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. If this event is a recurring event, <startTime> defines the dateTime when the recurrence window starts. The recurring master does not have to be an instance of the recurring event itself. An event in March set to recur every April will only appear in April.

[0469] The /getCalendarDaysResponse/event/body/endTime (dateTime minOccurs=1 maxOccurs=1) endTime method defines the end time of the event. An all-day event by convention ends at 11:59:59 PM of the ending day. This is stored in UTC. Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. The duration of the event is inferred from endTime-startTime.

[0470] The /getCalendarDaysResponse/event/body/allDay (boolean minOccurs=0 maxOccurs=1) element indicates a regular event by being false or being absent. Otherwise, this attribute indicates that the event is an all-day event. All day events may span multiple days. By convention, all day events start at 12:00:00 am of the day of startTime, regardless of what time it actually is, and it will end at 11:59:59 pm of the endTime date. In other words, if the allDay element is present and has value=true, .NET Calendar will ignore the actual times of the events and consider only the date part of the field.

[0471] The allDay tag is meant to operate as a hint to UI renders to display specialized icons indicating an all-day event. allDay events are distinguishable between 24-hr events starting at 12 am. In the case of a meeting request, an allDay event will not appear in the local user's time zone, but rather in the organizer's time zone.

[0472] The /getCalendarDaysResponse/event/body/floating (boolean minOccurs=0 maxOccurs=1) floating attribute indicates that this event is to occur in the current local time zone no matter what time zone the system is currently in (that is, it floats). For example, holidays are floating events. As another example, it may be useful to schedule medication regardless of an actual time zone, whereby a floating attribute is used with such an event. Floating values are stored as-is: no time-zone translations are needed to convert them to UTC or any local time zone.

[0473] The /getCalendarDaysResponse/event/body/travelTimeTo (int minOccurs=0 maxOccurs=1) field contains the amount of time (in minutes) that it takes to travel to the meeting location. The /getCalendarDaysResponse/event/body/travelTimeFrom (int minOccurs=0 maxOccurs=1) field contains the amount of time (in minutes) that it takes to return from the meeting location. These optional elements show in free/busy calculations.

[0474] The /getCalendarDaysResponse/event/body/freeBusyStatus (string minOccurs=0 maxOccurs=1) optional element annotates the freeBusy behavior of this event. Events by default appear as “busy”. The user may explicitly define this event to be annotated by setting .NET Calendar values to free, tentative, busy or away.

[0475] The /getCalendarDaysResponse/event/body/cuid (string minOccurs=0 maxOccurs=1) cuid (CorrelationUID) links an organizer's event to an attendee's event. It identifies which response from an attendee is for which request from an organizer, and which meeting request update from the organizer is for which previously accepted meeting by the attendee. The “cuid” is the same on both the attendee's and the organizer's copy of the appointment. It is also identical on the exception and the recurring master. This value is assigned by the .NET Calendar server and is non-modifiable.

[0476] The /getCalendarDaysResponse/event/body/organizer (minOccurs=0 maxOccurs=1) field contains the email address of the event organizer.

[0477] The /getCalendarDaysResponse/event/body/organizer/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /getCalendarDaysResponse/event/body/organizer/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/body/organizer/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0478] The /getCalendarDaysResponse/event/body/organizer/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /getCalendarDaysResponse/event/body/organizer/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element.

[0479] The /getCalendarDaysResponse/event/body/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional body elements.

[0480] The /getCalendarDaysResponse/event/attendeeEventExtra (minOccurs=0 maxOccurs=1) field contains additional information about an event, found only in an event invitee's schema. The /getCalendarDaysResponse/event/attendeeEventExtra/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0481] The /getCalendarDaysResponse/event/attendeeEventExtra/intendedFreeBusy (string minOccurs=0 maxOccurs=1) element is the event organizer's freeBusy information and is thus equal to event/freeBusyStatus. Invitees may overwrite event/freeBusyStatus with a new value, and intendedFreeBusy is intended to store the organizer's original freeBusyStatus.

[0482] The /getCalendarDaysResponse/event/attendeeEventExtra/responseTime (dateTime minOccurs=0 maxOccurs=1) field contains the reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what is maintained in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0483] The /getCalendarDaysResponse/event/attendeeEventExtra/responseType (string minOccurs=0 maxOccurs=1) accept status indicates the valid types of responses that an attendee can reply with {accept, decline, tentative, counterpropose}. The absence of this field indicates that no response has been recorded (either the invitation has not been sent, or that a reply has not been received).

[0484] The /getCalendarDaysResponse/event/attendeeEventExtra/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new start time for the meeting. This is stored in UTC.

[0485] The /getCalendarDaysResponse/event/attendeeEventExtra/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new end time for the meeting. This is stored in UTC.

[0486] The /getCalendarDaysResponse/event/attendeeEventExtra/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information. field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a location for the meeting.

[0487] The /getCalendarDaysResponse/event/attendeeEventExtra/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /getCalendarDaysResponse/event/attendeeEventExtra/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/attendeeEventExtra/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0488] The /getCalendarDaysResponse/event/attendeeEventExtra/delegateResponder (minOccurs=0 maxOccurs=1) field stores information of a delegate who responds on behalf of an invitee. The /getCalendarDaysResponse/event/attendeeEventExtra/delegateResponder/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /getCalendarDaysResponse/event/attendeeEventExtra/delegateResponder/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/attendeeEventExtra/delegateResponder/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0489] The /getCalendarDaysResponse/event/attendeeEventExtraldelegateResponder/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /getCalendarDaysResponse/event/attendeeEventExtra/delegateResponder/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /getCalendarDaysResponse/event/attendeeEventExtra/{any} (minOccurs=0 maxOccurs=unbounded) provides for additional attendee extra properties.

[0490] The /getCalendarDaysResponse/event/attachment (minOccurs=0 maxOccurs=unbounded) element contains attachment metadata, name, content-type and id's, and may also contain the attachmentBody. The /getCalendarDaysResponse/event/attachment/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0491] The /getCalendarDaysResponse/event/attachment/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0492] The /getCalendarDaysResponse/event/attachment/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /getCalendarDaysResponse/event/attachment/name (string minOccurs=1 maxOccurs=1) element contains information about an individual attachment in a mail message. The /getCalendarDaysResponse/event/attachment/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/attachment/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0493] The /getCalendarDaysResponse/event/attachment/contentType (string minOccurs=1 maxOccurs=1) element contains the content type of the attachment. The /getCalendarDaysResponse/event/attachment/contentTransferEncoding (string minOccurs=1 maxOccurs=1) element contains the encoding of the attachment. This information is necessary for decoding the attachment. The /getCalendarDaysResponse/event/attachment/size (unsignedLong minOccurs=1 maxOccurs=1) element contains the size of the attachment in bytes. The /getCalendarDaysResponse/event/attachment/attachmentBody (base64Binary minOccurs=1 maxOccurs=1) element contains the contents of the attachment.

[0494] The /getCalendarDaysResponse/event/reminder (minOccurs=0 maxOccurs=1) is directed to reminders. A user may optionally define a reminder for this appointment. Reminders for recurring appointments will be sent periodically before the appointment, as per the rules defined in the reminder subschema below. A non-recurring event may define no reminders, define a reminder with <set>=“true” or define a reminder with <set>=“false”.

[0495] A recurring meeting may have no reminders defined, or a recurring reminder defined with all instances receiving reminders. To define no reminders by default, but to define reminders for particular meeting instances in the exception body, a reminder <set>=“false” is created, and turned on and/or modified for particular instances. To define a recurring reminder, but turn it off for particular meeting instances, a reminder <set>=“true” is created, and turned off for particular instances.

[0496] If the event's reminder subschema is non-existent, yet the exception body has a reminder blob, then the exception reminder is ignored. An alternative is to require this.

[0497] The /getCalendarDaysResponse/event/reminder/@changeNumber (minOccurs=1 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read only to applications. Attempts to write this attribute are silently ignored.

[0498] The /getCalendarDaysResponse/event/reminder/@id (minOccurs=1 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services generates and assigns this ID during an insertRequest operation or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. After an ID has been assigned, the attribute is read only and attempts to write it are silently ignored.

[0499] The /getCalendarDaysResponse/event/reminder/@creator (minOccurs=1 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /getCalendarDaysResponse/event/reminder/set (boolean minOccurs=1 maxOccurs=1) field maintains a Boolean flag that indicates whether the reminder is active for this event. In most cases, this will be true, but in the case of a recurring appointment, this flag may default to true with specific instances not to be reminded, or default to false, with specific instances to be reminded.

[0500] The /getCalendarDaysResponse/event/reminder/to (string minOccurs=1 maxOccurs=1) stores a friendly name that this reminder is being sent to. The /getCalendarDaysResponse/event/reminder/to/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/reminder/to/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0501] The /getCalendarDaysResponse/event/reminder/offset (int minOccurs=1 maxOccurs=1) field specifies the offset, in minutes, of how long before the event the user should be reminded. Recommended values are set forth in the following table:

[0502]

Value	Description
5, 10, 20, 30, 45	5, 10, 20, 30, 45 minutes before the event
60, 120, 180,	1, 2, 3 hours before the event
startTime − startDay	The day of the event (reminder
	sent at 12:00 am)
startTime − (startDay −	“x” days before the event (reminder sent at
(1440 * x))	12:00 am “x” days before)

[0503] The /getCalendarDaysResponse/event/reminder/interruptability (int minOccurs=0 maxOccurs=1) optional element defines how interruptible this event is and it is used by notification routing software to make decisions about the relay and deferral of notifications that might occur while this meeting is active. The value contained in this element is a numeric value between one and ten. Low values represent a high cost of disruption, high values represent a low cost of disruption.

[0504] The /getCalendarDaysResponse/event/reminder/lastSentTime (dateTime minOccurs=1 maxOccurs=1) field is required by the reminder engine. The /getCalendarDaysResponse/event/reminder/nextTriggerTime (dateTime minOccurs=1 maxOccurs=1) determines the next time to trigger reminder.

[0505] The /getCalendarDaysResponse/event/attendee (minOccurs=0 maxOccurs=unbounded) includes the attendeeType, which contains the information about an attendee, including the display, email, puid, and the attendee's response.

[0506] The /getCalendarDaysResponse/event/attendee/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /getCalendarDaysResponse/event/attendee/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/attendee/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0507] The /getCalendarDaysResponse/event/attendee/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /getCalendarDaysResponse/event/attendee/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element. The /getCalendarDaysResponse/event/attendee/inviteType (string minOccurs=1 maxOccurs=1) is used by a meeting organizer to define the kind of invitee, e.g., as required, optional, or a resource (e.g., meeting room).

[0508] The /getCalendarDaysResponse/event/attendee/responseTime (dateTime minOccurs=0 maxOccurs=1) reply time on each attendee is set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what s/he maintains in his/her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0509] The /getCalendarDaysResponse/event/attendee/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new start time for the meeting. This is stored in UTC.

[0510] The /getCalendarDaysResponse/event/attendee/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType—[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new end time for the meeting. This is stored in UTC.

[0511] The /getCalendarDaysResponse/event/attendee/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information. field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a location for the meeting.

[0512] The /getCalendarDaysResponse/event/attendee/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /getCalendarDaysResponse/event/attendee/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /getCalendarDaysResponse/event/attendee/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0513] The /getCalendarDaysResponse/event/attendee/{any} (minOccurs=0 maxOccurs=unbounded) allows for extensibility.

[0514] The /getCalendarDaysResponse/event/recurrence/rule (minOccurs=1 maxOccurs=1) includes /getCalendarDaysResponse/event/recurrence/rule/creationDate (dateTime minOccurs=1 maxOccurs=1), which is required to determine which timezone recurrence rule to use. The startTime of the event is not used because of the ability to create events in the past and in the future.

[0515] The /getCalendarDaysResponse/event/recurrence/rule/firstDayOfWeek (string minOccurs=1 maxOccurs=1) stores what the first day of the week is for this user. Typical values are (su) Sunday or (mo) Monday. This is used for calculating the recurrence expansion, and allows recurring meetings to be expanded in the organizer's FirstDOW instead of the invitee's FirstDOW.

[0516] The /getCalendarDaysResponse/event/recurrence/rule/tzid (int minOccurs=0 maxOccurs=1) field identifies the time zone for this recurring event. All dateTime information in this event is stored in UTC (converted from the local time zone defined by the time zone sub-schema). If this field is absent, the recurring event is assumed to be recurring in UTC time. However, it is only a floating recurring event if the <floating> attribute is set:

[0517]

	<timeZone floating=“...”
id
=“...”>1..1
	<standardBias>1..1
</standardBias>
	<additionalDaylightBias>0..1
</additionalDaylightBias>0..1
	<standardDate>0..1
	<transitionRule weekdayOfMonth=“...” day=“...” dayOfMonth=“...” month=“...”
afterDay=“...”>1..1
</transitionRule>
	<transitionTime>1..1
<transitionTime>
	</standardDate>
	<daylightDate>0..1
	<transitionRule weekdayOfMonth=“...” day=“...” dayOfMonth=“...” month=“...”
afterDay=“...”>1..1
</transitionRule>
	<transitionTime>1..1
</transitionTime>
	</daylightDate>
	</timeZone>

[0518] The /getCalendarDaysResponse/event/recurrence/rule/isLeapYear (boolean minOccurs=0 maxOccurs=1) provides International calendar support. It is possible to derive isLeapYear from leapMonthValue, but .NET Calendar stores both separately. The /getCalendarDaysResponse/event/recurrence/rule/leapMonthValue (int minOccurs=0 maxOccurs=1)<leapMonthValue> cannot be derived from a particular year and thus must be stored. For example, a user creates a recurrence on a Hebrew Lunar calendar. The year is a leap year and it has 13 months. In that year, the leapMonthValue is 7.

[0519] The /getCalendarDaysResponse/event/recurrence/rule/repeat (minOccurs=1 maxOccurs=1) may includes the /getCalendarDaysResponse/event/recurrence/rule/repeat/daily (minOccurs=0 maxOccurs=), field, which specifies the number of days to repeat, e.g., repeat every [ . . . ] days. The /getCalendarDaysResponse/event/recurrence/rule/repeat/daily/@dayFrequency (int minOccurs=1 maxOccurs=1) specifies the periodicity of days over which repetition occurs, for example, repeat every 3 days.

[0520] The /getCalendarDaysResponse/event/recurrence/rule/repeat/weekly (minOccurs=0 maxOccurs=1) field, if present, is directed to repeating weekly, e.g., repeat every [ . . . ] week(s) on {su, mo, tu, we, th, fr, sa}. The presence of a weekday attribute means to repeat on this particular day. Any combination of the seven days is valid.

[0521] The /getCalendarDaysResponse/event/recurrence/rule/repeat/weekly/@weekFrequency (int minOccurs=0 maxOccurs=1) repeatWeekly recurrence occurs every period of weeks. If the attribute is not present, it defaults to 1 (every week).

[0522] The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthlyByDay (minOccurs=0 maxOccurs=1) specifies to repeat on the [First, Second, Third, Fourth, Last] {su, mo, tu, we, th, fr, sa} of every [ . . . ] month(s). Any combination of the {weekday} attributes are valid, including user-defined combinations for weekdays and weekend days.

[0523] The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthlyByDay/@monthFrequency (int minOccurs=0 maxOccurs=1) specifies the month periodicity to recur on. If this attribute is not present, it defaults to 1 (every month).

[0524] The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthlyByDay/@weekdayOfMonth (string minOccurs=1 maxOccurs=1) specifies which week in a month [first, second, third, fourth, last].

[0525] The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthly (minOccurs=0 maxOccurs=1) repeats the occurrence every month on a particular day. The very first occurrence is created from the parent event's startTime and endTime, but the recurrence occurs as follows: Repeat every month on [day] of [month]. Repeat every [monthFrequency] month(s) on [day] of [month]. Typically, the first occurrence is also an instance of the recurrence, but this need not be the case.

[0526] The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthly/@monthFrequency(int minOccurs=0 maxOccurs=1) optional attribute indicates the month periodicity. By default, it is 1, periodic every month. The start of the periodicity is determined from event startTime. The /getCalendarDaysResponse/event/recurrence/rule/repeat/monthly/@day (int minOccurs=1 maxOccurs=1) specifies the day of the month to recur on. Value is between one and 31.

[0527] A forceExact rule handles invalid day-month combinations. The proper recurrence pattern for repeating on the last day of the month is to use repeatMonthlyByDay. “Repeat on the [last] [day, weekday, weekend day] of . . .”. By default, an invalid day-month combination will cause .NET Calendar to search backwards to find a valid day-month combination. If /getCalendarDaysResponse/event/recurrence/rule/repeat/monthly/@forceExact (boolean minOccurs=0 maxOccurs=1) is true, an invalid starting [month , day] combination such as [6, 31] is ignored and will not be included as an instance of the recurrence. With forceExact, day=31 will only pick up months that have 31 days, day=30 will pick up all months except February, day=29 will pick up all months except February, except on leap years. February 29 is included on leap years.

[0528] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearlyByDay (minOccurs=0 maxOccurs=1) specifies how to repeat on the [First, Second, Third, Fourth, Last] {su, mo, tu, we, th, fr, sa} of [Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec] every [yearFrequency] years.

[0529] Any combination of the {weekday} attributes are valid, including user-defined combinations denoting weekdays and weekend days. This element's attributes contain whether a given day is or is not considered by the user as part of the work week. If this element has no attributes, it is assumed that the user has a Monday to Friday work week.

[0530] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearlyByDay/@yearFrequency (int minOccurs=0 maxOccurs=1) optional attribute indicates the year periodicity. By default, it is 1 (repeat every year).

[0531] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearlyByDay/@weekdayOfMonth (string minOccurs=1 maxOccurs=1) Specifies which week in a month [first, second, third, fourth, last] to repeat.

[0532] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearlyByDay/@month (int minOccurs=1 maxOccurs=1) contains a value between one and thirteen (some calendars have thirteen months).

[0533] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearly (minOccurs=0 maxOccurs=1) specifies to repeat every year on a particular date. The very first occurrence is created from the parent event's startTime and endTime, but the recurrence occurs as follows: Repeat yearly on [day] of [month]. Repeat every [yearFrequency] years on [day] of [month]. Typically, the first occurrence is also an instance of the recurrence, but this need not be the case.

[0534] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearly/@yearFrequency (int minOccurs=0 maxOccurs=1) optional attribute indicates the year periodicity. By default, it is 1 (repeat every year). The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearly/@month (int minOccurs=1 maxOccurs=1) specifies the month to recur on.

[0535] The /getCalendarDaysResponse/event/recurrence/rule/repeat/yearly/@day (int minOccurs=1 maxOccurs=1) specifies the day of the month to recur on. The value is between 1-31, and forceExact, applies for invalid day-month combinations. Thus, by default, an invalid day-month-year combination will cause .NET Calendar to search backwards to find a valid day for a particular month, year. If /getCalendarDaysResponse/event/recurrence/rule/repeat/yearly/@forceExact (boolean minOccurs=0 maxOccurs=1) is true, an invalid starting [month , day] combination such as [6, 31] is ignored and will not be included as an instance of the recurrence. With forceExact, .NET Calendar, day=31 will only pick up months that have 31 days, day=30 will pick up all months except February, day-29 will pick up all months except February, except on leap years. February 29 is included on leap years.

[0536] The /getCalendarDaysResponse/event/recurrence/rule/repeat/{any} (minOccurs=0 maxOccurs=unbounded) allows for any additional repeat rules.

[0537] The /getCalendarDaysResponse/event/recurrence/rule/windowEnd (dateTime minOccurs=0 maxOccurs=1) field indicates the end of the window over which the recurrence occurs. This is stored in UTC. The Maximum range is Jan. 1, 1753 to Dec. 31, 9999 to an accuracy of 3.33 milliseconds. Note that windowEnd, repeatForever, repeatInstances may be selectable.

[0538] The /getCalendarDaysResponse/event/recurrence/rule/repeatForever (boolean minOccurs=0 maxOccurs=1) overrides the windowEnd date and specifies that this recurrence repeats forever. Client implementations cannot depend on date values repeating forever, like 23:59:59 pm Dec. 31, 9999 or 23:59 Aug. 31, 4500.

[0539] The /getCalendarDaysResponse/event/recurrence/rule/repeatInstances (int minOccurs=0 maxOccurs=1) overrides the windowEnd date and specifies that this recurrence repeats for the specified number of instances. As is apparent, repeatInstances and repeatForever are mutually exclusive, but repeatInstances will override repeatForever for errant schemas.

[0540] Note that if the method causes a failure response to be generated, the failure is noted by generation of a SOAP Fault message. Failures can include a failure to understand a header marked as “s:mustUnderstand”, a .NET My Services standard error, security violation, load-balance redirect, or any service-specific severe error condition.

[0541] The myCalendar/getFreeBusyDays Method is accessed using a request message, and in response may generate a response message or a SOAP Fault message. The following sample document outlines and descriptions below illustrate the structure and meaning of the elements and attributes in the request and response messages:

[0542]

<m:getFreeBusyDaysRequest
	xmlns:m=“http://schemas.micro soft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/core”>1..1
	<m:calendarType>0..1</m:calendarType>
	<m:startTime>1..1</m:startTime>
	<m:endTime>1..1</m:endTime>
	<m:getFreeBlocks>0..1</m:getFreeBlocks>
	<m:returnIndividualBlocks>0..1</m:returnIndividualBlocks>
</m:getFreeBusyDaysReguest>

[0543] The /getFreeBusyDaysRequest (minOccurs=1 maxOccurs=1) function returns a stream of xml fragments defining the user's freeBusy information between two dates. Single events and recurring events within the time window are translated into blocks of free/busy time. The getFreeBusyDays only returns the blocks and their associated type. There is no explicit method to return unmerged freeBusy info, as that kind of behavior is fully contained within getCalendarDays.

[0544] This method follows the precedence order: Away(OOF), Busy, Tentative, Free. Overlapping blocks of the same freeOrBusyStatus kind are coalesced to form larger blocks. Overlapping blocks of different freeOrBusyStatus are overlaid. The events with higher precedence overlay on top (not by starting time). For example, Busy from 8 to 9, Tentative from 8:30 to 10, OOF from 9:30 to 11, Free from 10:30 to 12, is merged as Busy from 8 to 9, Tentative from 9 to 9:30, OOF from 9:30 to 11, Free from 11 to 12.

[0545] The freeBusy information of multiple users is retrieved by specifying a puid for each user in question. The caller of this function needs to specify their own puid, no implicit assumptions are made. The calling method takes a startDate and an endDate to define the duration over which freebusy information is returned. A third parameter determines if free blocks are explicitly returned. Free blocks are intervals where no calendar object exists.
The getFreeBusyDays method may be used to retrieve multiple calendar data from other users using <h:key instance=“0” cluster=“0” puid=“xyz”/> in the SOAP headers provided that puid “xyz” is provisioned on the .NET Calendar server, and provided that the user has been granted access in puid “xyz”'s rolelist.

[0546] The /getFreeBusyDaysRequest/calendarType (string minOccurs=0 maxOccurs=1) contains the optional calendar type to return, with the default being Gregorian. The /getFreeBusyDaysRequest/startTime (dateTime minOccurs=1 maxOccurs=1) field contains the starting time window of calendar objects to retrieve. This dateTime also contains the timeZone to retrieve the calendar information in.

[0547] The /getFreeBusyDaysRequest/endTime (dateTime minOccurs=1 maxOccurs=1) field contains the ending time window to retrieve calendar objects. This dateTime also contains the timeZone to retrieve the calendar information in, and needs to be the same timeZone as startTime.

[0548] The /getFreeBusyDaysRequest/getFreeBlocks (boolean minOccurs=0 maxOccurs=1) boolean causes .NET Calendar to explicitly return free time as freeBusy blocks. By default, free blocks are not returned. The /getFreeBusyDaysRequest/returnIndividualBlocks (boolean minOccurs=0 maxOccurs=1) boolean causes .NET Calendar not to coalesce/merge freeBusy information. By default, freeBusy information is merged.

[0549] Upon successful completion of the getFreeBusyDays method, a myCalendar/getFreeBusyDaysResponse response message is generated. The format of the response message is described below:

[0550]

<m:getFreeBusyDaysResponse selectedNodeCount=“...” status=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:freeOrBusyEvent>0..unbounded
	<m:startTime>1..1</m:startTime>
	<m:endTime>1..1</m:endTime>
	<m:type>1..1</m:type>
	</m:freeOrBusyEvent>
</m:getFreeBusyDaysResponse>

[0551] The /getFreeBusyDaysResponse (minOccurs=1 maxOccurs=1) response XML blob format, comprises freebusy xml fragments. The /getFreeBusyDaysResponse/@selectedNodeCount (int minOccurs=0 maxOccurs=1) attribute is used to return the number of selected nodes, selected by the corresponding data language operation.

[0552] The /getFreeBusyDaysResponse/@status (string minOccurs=1 maxOccurs=1) attribute indicates the status of the method, e.g., success when the corresponding method was completed successfully, failure when the corresponding method was not completed successfully, rollback when the method failed, but was rolled back to its pre-updateBlock status, or notAttempted when the corresponding method was not attempted. This occurs when a previous operation failed.

[0553] The /getFreeBusyDaysResponse/freeOrBusyEvent (minOccurs=0 maxOccurs=unbounded) includes /getFreeBusyDaysResponse/freeOrBusyEvent/startTime (dateTime minOccurs=1 maxOccurs=1) which specifies the start time, /getFreeBusyDaysResponse/freeOrBusyEvent/endTime (dateTime minOccurs=1 maxOccurs=1) which specifies the end time, and /getFreeBusyDaysResponse/freeOrBusyEvent/type (string minOccurs=1 maxOccurs=1) which specifies the type, including free, tentative, busy or away.

[0554] The myCalendar/getQuickView Method provides a QuickView/DatePicker service function. The following table and description below describes the request message for this method:

[0555]

[0556] The /getQuickViewRequest (minOccurs=1 maxOccurs=1) function provides an efficient, lightweight means to query a date range to indicate days that have 1 or more appointments (1) and days without appointments (0). Outlook® and OWA® (Outlook® Web Access) use this for their datepicker functionality. The date range takes timeZone-specific start and end times, using just the year, month, and day. The time zone can be a simple bias, since this is merely a request for data. startTime and endTime are required to have the same time-zone bias. In effect, the method “overlays” the incoming time zone onto the user's calendar to define the dayblocks for which the QuickView returns data.

[0557] The /getQuickViewRequest/calendarType (string minOccurs=0 maxOccurs=1) provides a field for the Optional calendar type to return, with the default being Gregorian. The /getQuickViewRequest/startTime (dateTime minOccurs=1 maxOccurs=1) field contains the starting time window of calendar objects to retrieve. This dateTime also contains the timeZone to retrieve the calendar information in.

[0558] The /getQuickViewRequest/endTime (dateTime minOccurs=1 maxOccurs=1) specifies the ending time window to retrieve calendar objects. This dateTime also contains the timeZone to retrieve the calendar information in. It must be the same timeZone as startTime.

[0559] The /getQuickViewRequest/tzid (int minOccurs=0 maxOccurs=1) field optionally specifies a timezone to retrieve the quickView in. If this or biasOffset are both missing, TZ_UTC is assumed. The /getQuickViewRequest/biasOffset (int minOccurs=0 maxOccurs=1) field optionally specifies a numeric integer offset timezone bias to retrieve the quickView in. tzid takes precedence over biasOffset (pending xsd:choice).

[0560] Upon successful completion of the myCalendar/getQuickViewmethod, a myCalendar/getQuickViewResponse response message is generated. The format of the response message is described in the table and description below:

[0561]

<m:getQuickViewResponse selectedNodeCount=“...” status=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10core”>1..1
	<m:month m=”...” year=“...”>1..unbounded
	<m:day d=“...”>1..31</m:day>
	</m:month>
</m:getQuickViewResponse>

[0562] The /getQuickViewResponse (minOccurs=1 maxOccurs=1) return value of getQuickView is a list of calendar days grouped into months. The /getQuickViewResponse/@selectedNodeCount (int minOccurs=0 maxOccurs=1) attribute is used to return the number of selected nodes, selected by the corresponding data language operation. The /getQuickViewResponse/@status (string minOccurs=1 maxOccurs=1) attribute indicates the status of the method, e.g., success when the corresponding method was completed successfully, failure when the corresponding method was not completed successfully, rollback when the method failed, but was rolled back to its pre-updateBlock status, or notAttempted when the corresponding method was not attempted. This occurs when a previous operation failed.

[0563] The /getQuickViewResponse/month (minOccurs=1 maxOccurs=unbounded) field specifies the month block for the grouping of calendar days. The /getQuickViewResponse/month/@m (int minOccurs=0 maxOccurs=1) provide a month number, restrict to between one and thirteen, (as some calendars have thirteen months).

[0564] The /getQuickViewResponse/month/@year (int minOccurs=0 maxOccurs=1), provides the year, while the /getQuickViewResponse/month/day (boolean minOccurs=1 maxOccurs=31) field specifies whether this day is free (0) or has at least one event on it or overlapping (1). The /getQuickViewResponse/month/day/@id (int minOccurs=0 maxOccurs=1) field specifies a day in this month.

[0565] The myCalendar/sendMeeting method is directed to the organizer meeting request, is accessed using a request message, and in response may generate a response message or a SOAP Fault message. The following sample document fragments illustrate the structure and meaning of the elements and attributes in the request and response messages. The following table and description below describes the request message for this method:

[0566]

<m:sendMeetingRequest eventId=“...” criticalChange=“...” recurrenceId=“...”
continueOnFailure=“...” deleteOnCompletion=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”

	<m:uninvite behavior=“...”>1..1

	<hs:puid>0..1</hs:puid>
	<hs:email>0..1</hs:email>
	</m:attendee>
	</m:uninvite>
	<m:replaceRequest select=“...” useClientIds=“...” minOccurs=“...” maxOccurs=“...”>0..1
	<hs:options>0..1 {any}</hs:options>
	<hs:attributes {any}=“...”>0..unbounded</hs:attributes>
	{any}
	</m:replaceRequest>
	<m:invite behavior=“...”>1..1
	<m:attendee>0..unbounded
	<hs:name xml:lang=“...” dir=“...”>0..1</hs:name>
	<hs:puid>0..1</hs:puid>
	<hs email>0..1</hs email>
	</m:attendee>
	</m:invite>
</m:sendMeetingRequest>

[0567] The purpose of this method is for a meeting organizer to invite and uninvite (cancel) attendees to this event. The /sendMeetingRequest (minOccurs=1 maxOccurs=1) sendMeeting also sends updated invitations to existing invitees. Inviting a user to a single instance of a recurring event will cause only that instance to be sent. However, future updates to that event will overwrite the existing instance, including the case where an update is the full recurring event. Meeting requests will be sent out as attachments from an SMTP server. When inviting or uninviting, .NET Calendar searches for these existing attendees by puid first, and then by email address such that the puid receives precedence in the search predication. .NET Calendar will not allow multiple meeting requests/cancellations to the same puid or email address within the scope of the same invite or uninvite block. However, an organizer may uninvite an attendee and then reinvite again (non-standard behavior).

[0568] The /sendMeetingRequest/@eventId (string minOccurs=1 maxOccurs=1) field contains the puid of the event which to send meeting invitations or cancellations to. This event must already exist within the .NET Calendar service. Additional server constraints are implemented which verify that potential updates to the attendee tables occur for this event only. This is a required field.

[0569] The /sendMeetingRequest/@criticalChange (boolean minOccurs=0 maxOccurs=1) attribute, when set to “true”, causes <lastUpdateTime> to be updated when invitations are sent to the attendees. If “false”, <lastUpdateTime> remains untouched.

[0570] The /sendMeetingRequest/@recurrenceId (dateTime minOccurs=0 maxOccurs=1) optional recurrenceId allows the meeting organizer to send invitations for only a particular instance of a recurring event. If the event is not a recurring event, or if recurrenceId does not correspond to a valid instance/exception, sendMeetingRequest will fail with an error.

[0571] The /sendMeetingRequest/@continueOnFailure (boolean minOccurs=1 maxOccurs=1) field specifies to .NET Calendar to continue performing the sendMeetingRequest even on a failure. Points of failure: <uninvite> may delete attendees, and the data language delete may encounter errors <updateRequest> may encounter data language errors. The optional final delete of the event may encounter errors.

[0572] The /sendMeetingRequest/@deleteOnCompletion (boolean minOccurs=0 maxOccurs=1) event will be deleted upon completion of this sendMeetingRequest. This behavior is intended for deleting a meeting and sending cancellations. If recurrenceId is present (and valid), only this particular recurring instance or exception is deleted, in which case a new <deletedExceptionDate> is added to the recurrence rule.

[0573] The /sendMeetingRequest/uninvite (minOccurs=1 maxOccurs=1) includes The /sendMeetingRequest/uninvite/@behavior (string minOccurs=0 maxOccurs=1), an attribute that gives the option to either choose to send cancellations to “all” attendees in the event's attendee table, or send to “none” of them. A third value of “default” would give the default behavior of sending cancellations to all attendees who are replaced in the <replaceRequest> block. When this attribute is set, .NET Calendar will ignore anything within the <uninvite> node.

[0574] The /sendMeetingRequest/uninvite/attendee (minOccurs=0 maxOccurs=unbounded) field contains a list of people to uninvite. Uninvited attendees must already exist in the organizer's attendee table, or else these users are ignored.

[0575] The /sendMeetingRequest/uninvite/attendee/@deleteAttendee (boolean minOccurs=0 maxOccurs=1) field optionally specifies whether or not to delete this attendee from the organizer's attendee table. If the attendee is not deleted, .NET Calendar will not know the status of this attendee because the status {not-sent, sent, cancelled} is not stored per-attendee.

[0576] The /sendMeetingRequest/uninvite/attendee/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /sendMeetingRequest/uninvite/attendee/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /sendMeetingRequest/uninvite/attendee/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0577] The /sendMeetingRequest/uninvite/attendee/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /sendMeetingRequest/uninvite/attendee/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element.

[0578] The /sendMeetingRequest/replaceRequest (minOccurs=0 maxOccurs=1) replace request can only affect the meeting invitation in question, and is thus constrained to be only select=“/m:myCalendar/m:event[@id=@eventId]/ . . . ”. It will not be allowed to replace-on-null so that event creation cannot be a side-effect. The /sendMeetingRequest/replaceRequest/@select (string minOccurs=1 maxOccurs=1) attribute selects an xdb:blue or an xdb:red.

[0579] The /sendMeetingRequest/replaceRequest/@useClientIds (string minOccurs=0 maxOccurs=1) attribute specifies that, if an xdb:blue item is created during an insert or replace operation, and an ID would normally be generated, the ID specified in the request content should be used instead of having .NET My Services generate an ID. Applications using this option must ensure that they are properly generating unique IDs in the form of UUIDs. They must also ensure that they do not assign the same ID to multiple xdb:blue items; this can happen if the insert select attribute selects multiple nodes.

[0580] The /sendMeetingRequest/replaceRequest/@minOccurs (int minOccurs=0 maxOccurs=1) optional attribute specifies the minimum number of nodes that must be selected by the select operation in order for this operation to be successfully attempted. The default value is zero, meaning that if no nodes are selected, the operation silently succeeds as a no operation (“NOP”). A value of one means that a minimum of one node must be selected. In that case, if no nodes are selected, the operation fails with an error.

[0581] The /sendMeetingRequest/replaceRequest/@maxOccurs (int minOccurs=0 maxOccurs=1) optional attribute specifies the maximum number of nodes that maybe selected by the select operation in order for this operation to be successfully attempted. The default value is unbounded. If the number of nodes selected by the select attribute is greater than this value, an error condition occurs. The /sendMeetingRequest/replaceRequest/options (minOccurs=0 maxOccurs=1) provide for options.

[0582] The /sendMeetingRequest/replaceRequest/options/{any} (minOccurs=0 maxOccurs=unbounded) includes /sendMeetingRequest/replaceRequest/attributes (minOccurs=0 maxOccurs=unbounded). This element is used to specify a single attribute to be manipulated by the .NET My Services data-manipulation primitives. For example, when used in an insertRequest, this element specifies an attribute to be inserted at the specified node.

[0583] The /sendMeetingRequest/replaceRequest/attributes/@ {any} (minOccurs=0 maxOccurs=1) and /sendMeetingRequest/replaceRequest/{any} (minOccurs=0 maxOccurs=unbounded) fields provide for extensibility. This element is a placeholder that indicates where the content of the item being replaced is to be specified.

[0584] The /sendMeetingRequest/invite (minOccurs=1 maxOccurs=1) includes the /sendMeetingRequest/invite/@behavior (string minOccurs=0 maxOccurs=1) attribute. This attribute will give the option to either choose to send invitations to “all” attendees in the event's attendee table, or send to “none” of them. A third value of “default” would give the default behavior of sending invitations to only the new attendees in the <replaceRequest> block. When this attribute is set, .NET Calendar will ignore anything within the <invite> node.

[0585] The /sendMeetingRequest/invite/attendee (minOccurs=0 maxOccurs=unbounded) field contains information about this attendee to be invited. An invited attendee must already exist in the organizer's attendee table. This attendee may originally be there prior to the sendMeetingRequest method, or be the result of the update operation to this meeting. To change the attendee's inviteType, the update operation should be used.

[0586] When invitations are sent, the attendee's <responseTime> is set to the current time (now) as a side-effect. The /sendMeetingRequest/invite/attendee/name (string minOccurs=0 maxOccurs=1) optional element specifies the name for the enclosing element. The /sendMeetingRequest/invite/attendee/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /sendMeetingRequest/invite/attendee/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0587] The /sendMeetingRequest/invite/attendee/puid (string minOccurs=0 maxOccurs=1) optional element specifies the PUID for the enclosing element. The /sendMeetingRequest/invite/attendee/email (string minOccurs=0 maxOccurs=1) optional name specifies an e-mail address for the enclosing element.

[0588] The myCalendar/respond method provides a method for invitees to respond to an invite. The following table and accompanying description below illustrate the structure and meaning of the elements and attributes in the request and response messages:

[0589]

xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:responseTime>0..1</m:responseTime>
	<m:responseType>0..1</m:responseType>
	<m:counterProposeStartTime>0..1</m:counterProposeStartTime>
	<m:counterProposeEndTime>0..1</m:counterProposeEndTime>
	<m:counterProposeLocation>0..1</m:counterProposeLocation>
	<m:responseBody xml:lang=“...” dir=“...”>0..1</m:responseBody>
	<m:eventId>1..1</m:eventId>
	<m:puid>1..1</m:puid>
</m:respondRequest>

[0590] The purpose of this method is for a meeting invitee to respond to an invitation. Invitees may accept, decline, accept tentatively, or counterpropose in some means. Currently, allow the counterproposing of time and location, but we may consider future additions.

[0591] The /respondRequest (minOccurs=1 maxOccurs=1) includes

[0592] /respondRequest/responseTime (dateTime minOccurs=0 maxOccurs=1), field is the reply time on each attendee, set to the current time (Now) when the organizer sends a meeting invitation. When the attendee responds, they update their responseTime. When the organizer receives responses, they will honor only those that have a higher responseTime than what he or she maintains in his or her own copy of the event for each attendee. While processing the response, the organizer will update their responseTime. This guarantees that the organizer honors only the most recent response from the attendee. This is stored in UTC.

[0593] The /respondRequest/responseType (string minOccurs=0 maxOccurs=1) accept status indicates the valid types of responses that an attendee can reply with {accept, decline, tentative, counterpropose}. The absence of this field indicates that no response has been recorded (either the invitation has not been sent, or that a reply has not been received).

[0594] The /respondRequest/counterProposeStartTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal start time information. If responseType=[counterPropose], then either the startTime, endTime, or location, or all three can be present. This is the invitee's counterProposal for a new start time for the meeting. This is stored in UTC.

[0595] The /respondRequest/counterProposeEndTime (dateTime minOccurs=0 maxOccurs=1) field contains the counter proposal end time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterproposal for a new end time for the meeting. This is stored in UTC.

[0596] The /respondRequest/counterProposeLocation (string minOccurs=0 maxOccurs=1) field contains the counter proposal location information. field contains the counter proposal start time information. If responseType=[counterPropose], then either the {startTime, endTime}, or location, or both can be present. This is the invitee's counterProposal for a location for the meeting.

[0597] The /respondRequest/responseBody (string minOccurs=0 maxOccurs=1) field contains an optional message for invitees to include along with the response. The /respondRequest/responseBody/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /respondRequest/responseBody/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left) and ltr (left to right).

[0598] The /respondRequest/eventId (string minOccurs=1 maxOccurs=1) field contains the eventId for the meeting, and the /respondRequest/puid (string minOccurs=1 maxOccurs=1) field identifies the invitee.

[0599] The myCalendar/updateReminder Method provides a Delegate function to the .NET Alerts service for creating or modifying calendar meeting reminders. The following sample document in the table and accompanying description below illustrate the structure and meaning of the elements and attributes in the request and response messages:

[0600]

<m:updateReminderRequest
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCalendar”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:reminder>1..1
	<m:set>1..1</m:set>
	<m:to xml:lang=“...” dir=“...”>1..1</m:to>
	<m:offset>1..1</m:offset>
	<m:interruptability>0..1</m:interruptability>
	<m:lastSentTime>1..1</m:lastSentTime>
	<m:nextTriggerTime>1..1</m:nextTriggerTime>
	</m:reminder>
	<m:id>1..1</m:id>
</m:updateReminderRequest>

[0601] The /updateReminderRequest (minOccurs=1 maxOccurs=1) function is used to update the status of a reminder once the user has received the notification. It also may be exposed as an HTTP API so that non-.NET My Services clients have a means to dismiss, snooze, or be reminded again at a different time. The /updateReminderRequest/reminder (minOccurs=1 maxOccurs=1) includes the /updateReminderRequest/reminder/set (boolean minOccurs=1 maxOccurs=1) Boolean flag that indicates whether the reminder is active for this event. In most cases, this will be true, but in the case of a recurring appointment, this flag may default to true with specific instances not to be reminded, or default to false, with specific instances to be reminded.

[0602] The /updateReminderRequest/reminder/to (string minOccurs=1 maxOccurs=1) field contains the friendly name that this reminder is being sent to. The /updateReminderRequest/reminder/to/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /updateReminderRequest/reminder/to/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left) and ltr (left to right).

[0603] The /updateReminderRequest/reminder/offset (int minOccurs=1 maxOccurs=1) field specifies the offset, in minutes, of how long before the event the user should be reminded. Recommended values are the following:

[0604]

Value	Description
5, 10, 20, 30, 45	5, 10, 20, 30, 45 minutes before the event
60, 120, 180,	1, 2, 3 hours before the event
startTime − startDay	The day of the event (reminder sent at
	12:00 am)
startTime − (startDay −	“x” days before the event (reminder
(1440 * x))	sent at 12:00 am “x” days before)

[0605] The /updateReminderRequest/reminder/interruptability (int minOccurs=0 maxOccurs=1) optional element defines how interruptible this event is and it is used by notification routing software to make decisions about the relay and deferral of notifications that might occur while this meeting is active. The value contained in this element is a numeric value between one and ten. Low values represent a high cost of disruption, high values represent a low cost of disruption.

[0606] The /updateReminderRequest/reminder/lastSentTime (dateTime minOccurs=1 maxOccurs=1) is used by the reminder engine. The /updateReminderRequest/reminder/nextTriggerTime (dateTime minOccurs=1 maxOccurs=1) field determines the next time to trigger reminder. The /updateReminderRequest/id (string minOccurs=1 maxOccurs=1) attribute contains a reference to another .NET My Services item by its item ID. The uuidType is used to specify a universally unique identifier (UUID).

[0607] Upon successful completion of this method, a Standard .NET My Services response message is generated as the myCalendar/updateReminderResponse.

myCalendar/Examples

[0608] By way of example, consider this stripped-down view of a sample user's calendar:

[0609]

<myCalendar>
	<event>
	<body>
	<cat ref=“hs:public”/>
	<title xml:lang=“en” dir=“ltr”>Meet with attorneys</title>
	<startTime> 2001-09-14T19:00:00Z </startTime>
	<endTime>2001-09-14T20:00:00Z</endTime>
	<organizer>
	<name>John Doe</name>
	<email>[email protected]</email>
	</organizer>
	</body>
	</event>
</m Calendar>

[0610] As can be seen from the various descriptions above, when interpreted by a calendar application, this would result in a single meeting on the calendar that takes place at noon Pacific Standard Time and lasts one hour.

[0611] As a more complex example, consider the following table:

[0612]

</m:myCalendar>

[0613] As can be seen from the descriptions above, this user has two events in a calendar. One event is recurring every Monday at 8:00 am, and the other is an upcoming event at 1:20 pm.

myCategories

[0614] The .NET myCategories service is designed to support a classification model for data within the .NET My Services universe. The classification model is generic and makes very few assumptions about application usage. As a result, the design is minimal and open. This model of categorization will be used by a wide spectrum of applications, without burdening the developer of the service.

[0615] The .NET myCategories service manages a list of category definitions. Examples of category definitions include child, anniversary, and employee. Each category definition has a human readable name and a description which contains hints about the meaning of that category. For example, one given category may imply a more general category, while “friends” implies acquaintances. A category may be classified by using other categories. For example, anniversary and birthday are categorized as specialDate.

[0616] Like other .NET My Services, the .NET Categories service exposes a global system document, and an identity centric content document. The global system document is an extension of the standard system document which contains global category definitions available to all .NET My Services applications. The identity-centric content document contains category definitions local to the identity.

[0617] Within other .NET My Services, category references are used to mark an XML element as belonging to the group represented by the category definition. The schema of each service defines which nodes (if any) can be categorized. For example, .NET Contacts/contacts/address can be categorized, but .NET Calendar/event/eventBody cannot. The roleList and system schemas also define nodes that can be categorized. For example, roleList/role can be categorized.

[0618] Categories use a declarative syntax for encoding relationships that an application deems as important. .NET My Services neither provides nor requires any consistency checks or enforcements implied by the semantics of these relationships.

[0619] There are two primary elements used to define and reference categories. The catDef element is used to define a category, and the cat element is used to refer to a category. .NET My Services allows the catDef element to appear in the system document of the .NET Categories service, the content document of the .NET Categories service and/or an arbitrary XML file located by a URI.

[0620] The cat element refers to a category definition by absolute or relative URI. The linkage between the two is through the catDef/@idName attribute and the cat/@ref attribute. The catDef/@idName attribute specifies the local id for the category definition, and the cat/@ref attribute is the value of that reference.

[0621] The value of the cat/@ref attribute may take the following form:

• • [0622] system #name-of-category

[0623] The category definition being referenced is located in the system document of the .NET Categories service, and its catDef/@idName attribute is “name-of-category”. For example, the category reference of <cat ref=“system#public”/> is a reference to the category definition whose catDef/@idName value is “public”, and that this category definition is located in the system document of the .NET Categories service i.e. <catDef idName=“public”/>.

[0624] The value of the cat/@ref attribute may also take the form:

• • [0625] content[?puid=puid-value]#name-of-category

[0626] The category definition being referenced is located in the content document of the .NET Categories service, and its catDef/@idName attribute is “name-of-category”. The instance of the .NET Categories service (i.e., the puid of the service) is implied by the context of the reference. This may be made explicit by inserting ?puid=puid-value to the URI, and when this is done, it means the content document of the .NET Categories service whose puid is “puid-value” holds the category definition. For example, the category reference of <cat ref=“content#LaQuintaHouse”/> is a reference to the category definition whose catDef/@idName value is “LaQuintaHouse”, and that this category definition is located in the content document of the .NET Categories service for the current puid i.e. <catDef idName=“LaQuintaHouse”/>.

[0627] The value of the cat/@ref attribute may also take the form:

• • [0628] any-uri#name-of-category

[0629] The category definition being referenced is located in an external (to .NET My Services) resource. The “any-uri” portion of the reference refers to a resource containing the catDef element whose @idName attribute matches the “name-of-category”. The mapping between the “any-uri” portion of the reference and an XML document containing the catDef elements is a function of the “any-uri”. By convention, this uri is the name of an XML document containing those elements. The purpose of this reference form is to allow and support a free form set of extended categorizations that are global and available to all. For example, the category reference of <cat ref=“http://schemas.cpandl.com/im/globalCategories.xml#imBuddy”/> is a reference to the category definition whose catDef/@idName value is “imBuddy”, and that this category definition is located in an external resource located at “http://schemas.cpandl.com/im/globalCategories.xml”. Note that it is expected that category definitions will exist in the appropriate locations, but there is no requirement or enforcement of this.

[0630] In the various cases, the mapping between a category reference and the category definition is very simple.

• • [0631] 1. Locate the document containing the category definition by taking the name prior to the “#”.
  • [0632] 2. If the document is “system”, then the document containing the category definition is the system document of the .NET Categories service and is addressed using request/@service=“myCategories” and request/@document=“system”.
  • [0633] 3. If the document is “content”, then the document containing the category definition is the content document of the .NET Categories service and is addressed using request/@service=“myCategories” and request/@document=“content”. If the ?puid=puid-value argument is present, the request is further qualified by request/key/@puid=“puid-value”. Otherwise, this attribute contains the puid of the document containing the reference.
  • [0634] 4. For any other document, the value is the uri of the XML document containing the category definition.
  • [0635] 5. Locate the category id which is the portion of the reference after the “#”.
  • [0636] 6. With the document in hand, the xpath expression //catDef[@idName=‘category-id’] selects the category definition.
    myCategories/Roles

[0637] The myCategories service controls access by using the rt0, rt1, rt2, rt3 and rt99 roleTemplates, using the following scopes:

[0638]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>
	<hs:shape base=t>
	</hs:shape>
</hs:scope>

	<hs:include select=//*[cat/@ref=‘hs:public’]/>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0639] The myCategories roleTemplate rt0 role gives complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myCategories service through that method while mapped to this roleTemplate:

[0640]

TABLE
myCategories roleTemplate rt0
	method	scope/name
	Query	allElements
	Insert	allElements
	Replace	allElements
	Delete	allElements
	Update	allElements

[0641] The myCategories roleTemplate rt1 role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. They may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myCategories service through that method while mapped to this roleTemplate:

[0642]

TABLE
myCategories roleTemplate rt1
	method	scope/name
	Query	allElements
	Insert	onlySelfElements
	Replace	onlySelfElements
	Delete	onlySelfElements

[0643] The myCategories roleTemplate rt2 role gives complete read access to the information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myCategories service through that method while mapped to this roleTemplate:

[0644]

TABLE
myCategories roleTemplate rt2
	method	scope/name
	Query	allElements
	Insert	onlySelfSubscriptionElements
	replace	onlySelfsubscriptionElements
	Delete	onlySelfsubscriptionElements

[0645] The myCategories roleTemplate rt3 role gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myCategories service through that method while mapped to this roleTemplate:

[0646]

myCategories roleTemplate rt3
	method	scope/name
	Query	onlyPublicElements

[0647] The myCategories roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99.

myCategories/Content

[0648] The content document is an identity centric document, with its content and meaning a function of the user identifier (puid) used to address the service. Accessing the document is controlled by the associated roleList document. The following table comprises a schema outline that illustrates the layout and meaning of the information found in the content document for the myCategories service:

[0649]

<m:myCategories changeNumber=“...” instanceId=“...”
	xmlns:m=“http://schemas.microsoft.com/hs/2001/10/myCategories”
	xmlns:hs=“http://schemas.microsoft.com/hs/2001/10/core”>1..1
	<m:catDef idName=“...” changeNumber=“...”
	id=“...” creator=“...”>0..bounded
	<hs:name xml:lang=“...” dir=“...”>0..bounded</hs:name>
	<hs:description xml:lang=“...” dir=“...”>0..1</hs:description>
	<hs:implies ref=“...”>0..unbounded</hs:implies>
	<hs:cat ref=“...”>0..unbounded</hs:cat>
	{any}
	</m:catDef>
	<m:subscription changeNumber=“...” id=“...”
	creator=“...”>0..bounded
	<hs:trigger select=“...” mode=“...”
	baseChangeNumber=“...”>1..1</hs:trigger>
	<hs:expiresAt>0..1</hs:expiresAt>
	<hs:context uri=“...3[>1..1{any}</hs:context>
	<hs:to>1..1</hs:to>
	</m:subscription>
	{any}
</m:myCategories>

[0650] The meaning of the attributes and elements shown in the table are set forth below, wherein in the syntax used in the table, boldface type corresponds to a blue node, and underlined type to a red node, as described above, and the minimum and maximum occurrence information (0, 1, unbounded) indicates whether an element or attribute is required or optional, and how many are possible.

[0651] The /myCategories (minOccurs=1 maxOccurs=1) element encapsulates the content document for the .NET Categories service. The service is designed to store identity centric category definitions that may be referred to using the content[?puid=puid-value]#name-of-category relative URI scheme. The /myCategories/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0652] The /myCategories/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a user is provisioned for a particular service.

[0653] The /myCategories/catDef (minOccurs=0 maxOccurs=unbounded) element encapsulates the definition of a category and may appear in the system or content document of the .NET Categories service, or may appear in an external resource.

[0654] The /myCategories/catDef/@idName (string minOccurs=0 maxOccurs=1) attribute specifies the name of the category definition in the form of the category name. The relationship between this value, and references to this value, are defined using the rules outlined above.

[0655] The /myCategories/catDef/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0656] The /myCategories/catDef/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0657] The /myCategories/catDef/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myCategories/catDef/name (string minOccurs=0 maxOccurs=unbounded) element specifies the localized name of the category. The /myCategories/catDef/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCategories/catDef/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left), and ltr (left to right).

[0658] The /myCategories/catDef/description (string minOccurs=0 maxOccurs=1) element specifies a full description of the category definition. The /myCategories/catDef/description/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /myCategories/catDef/description/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left), or ltr (left to right).

[0659] The /myCategories/catDef/implies (minOccurs=0 maxOccurs=unbounded) element specifies that this category definition also implies that another category (designated by the ref attribute) also applies. The /myCategories/catDef/implies/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined above.

[0660] The /myCategories/catDef/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid. The /myCategories/catDef/cat/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined above.

[0661] The /myCategories/catDef/{any} (minOccurs=0 maxOccurs=unbounded) and /myCategories/{any} (minOccurs=0 maxOccurs=unbounded) fields allow for extensibility, like other “any” fields.

myCategories/System

[0662] The system document is a global document for the service, having a content and meaning that are independent of the puid used to address the service. The document is read only to all users. The system document contains a set of base items common to other services in the .NET MyServices model, as described above in the common system section of the present application, (with myCategories as the *actual service name* to insert) and is extended to include service-specific global information by the following:

[0663] This schema outline in the table below illustrates the layout and meaning of the information for the myCategories service, wherein the category definitions may be referenced by using the system#name-of-category notation in the cat/@ref attribute as described above.

[0664]

TABLE
myCategories/system
	:
	:	see common system
	:
	<sys:catDef idName=“...” changeNumber=“...”
	id=“...” creator=“...”>0..unbounded
	<hs:name xml:lang=“...” dir=“...”>0..unbounded</hs:name>
	<hs:description xml:lang=“...” dir=“...”>0..1</hs:description>
	<hs:implies ref=“...”>0..unbounded</hs:implies>
	<hs:cat ref=“...”>0..unbounded</hs:cat>
	{any}
	</sys:catDef”
	{any}
</sys:system>

[0665] The meaning of the attributes and elements shown in the preceding sample document outline are listed below, using the syntax described above for blue (bold) and red nodes (underlined). The common system items are described in the common system documents section above.

[0666] The /system/catDef (minOccurs=0 maxOccurs=unbounded) element encapsulates category definitions global and accessible to all .NET My Services applications. Category references of the form system#name-of-category may be used to refer to these category definitions. The /system/catDef/@idName (string minOccurs=0 maxOccurs=1) attribute specifies the name of the category definition in the form of the category name. The relationship between this value, and references to this value, are defined using the rules outlined above.

[0667] The /system/catDef/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0668] The /system/catDef/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0669] The /system/catDef/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The system/catDef/name (string minOccurs=0 maxOccurs=unbounded) element specifies the localized name of the category. The /system/catDef/name/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /system/catDef/name/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the default layout direction for the localized string. Valid values are rtl (right to left), and ltr (left to right).

[0670] The /system/catDef/description (string minOccurs=0 maxOccurs=1) element specifies a full description of the category definition. The /system/catDef/description/@xml:lang (minOccurs=1 maxOccurs=1) required attribute is used to specify an ISO 639 language code or an ISO 3166 country code as described in RFC 1766. The value of this attribute indicates the language type of the content within this element. The /system/catDef/description/@dir (string minOccurs=0 maxOccurs=1) optional attribute specifies the base direction of directionally neutral text. Possible values include rtl (right to left), or ltr (left to right).

[0671] The /system/catDef/implies (minOccurs=0 maxOccurs=unbounded) element specifies that this category definition also implies that another category (designated by the ref attribute) also applies. The /system/catDef/implies/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined above. The /system/catDef/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid.

[0672] The /system/catDef/cat/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined above. The /system/catDef/{any} (minOccurs=0 maxOccurs=unbounded) and /system/{any} (minOccurs=0 maxOccurs=unbounded) fields provide for extensibility.

myContacts

[0673] The .NET Contacts service comprises a repository for a user to store and track contact information and relationships for the various people and organizations that the user interacts with. To this end, each .NET My Services user has access to a logical contacts document which may contain multiple contact records. In general, the .NET Contacts service thus forms the foundation for an electronic address book, or a set of electronic relationships. This service contains a list of contacts, organized by category, wherein a contact is a schema element containing an identifier (id) for the contact in the .NET My Services id space. A contact has a local name for that contact, a set of categories that the contact belongs to, (distribution list's, groups, and classifications), an address, as defined by the .NET Address schema, and a set of profile information (as defined by a corresponding .NET Profile schema). To this end, the .NET Contacts schema includes at least some of the .NET Profile service information including, but not limited to, name, addresses, phone numbers and email addresses, as well as allowing the owner to control how the contacts are categorized.

[0674] Contact information stored within .NET Contacts can be derived from the owner's .NET Address and .NET Profile services. For example, if a user X wishes to add someone named Y as a contact in the user's .NET Contacts service, the information used to populate this contact can be queried from user Y's .NET Address and .NET Profile services. User Y's access control mechanisms determine how much information from his or her .NET Address and .NET Profile services are allowed to be seen. From the user's perspective, the user can similarly control visibility of individual contacts and grant various levels access to their list of contacts to applications and other users based on the role templates with respect to each user's relative role. Thus, for example, with the user's consent, an application could populate a selection box with the user's contacts. From this box, the user could select a contact and the application could fill out the “Ship To:” fields (name, address, city, state and zip) for the contact automatically, such as when making a gift purchase.

[0675] The .NET Contacts service is designed to support live contacts. In this mode of operation, the queries described above that populate a contact happen automatically each time a change occurs in a subscribed-to to contact. This synchronization can be enabled or suppressed on a contact-by-contact basis. Users and applications can negotiate a subscription to another user's Profile document via the LiveContacts mechanism. When subscribed, the informational nodes become read-only for that contact and automatically update when changed by the Profile owner. The user can still control categorization, and notes for the LiveContact entry. The service-to-service communications protocol (SSCP) provides a highly efficient, robust mechanism for such automatic updates, as described below.

myContacts/Roles

[0676] The myContacts service controls access by using the roleTemplates rt0, rt1, rt2, rt3 and rt99, using the following scopes:

[0677]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>

	<hs:include se1ect=//subscription[@creator=‘$callerId’[/>
	</hs:shape>
</hs:scope>

[0678] The myContacts roleTemplate rt0 role gives complete read/write access to the information within the content document of the service being protected through this roleTemplate.

[0679] The following table illustrates the available methods and the scope in effect when accessing the myContacts service through that method while mapped to this roleTemplate:

[0680]

TABLE
myContacts roleTemplate rt0

	insert	allElements
	replace	allElements
	delete	allElements
	update	allElements
	updateContactData	allElements
	serviceOnline	allElements
	serviceOffline	allElements

[0681] The myContacts roleTemplate rt1 role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. They may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myContacts service through that method while mapped to this roleTemplate:

[0682]

	insert	onlySelfElements
	replace	onlySelfElements
	delete	onlySelfElements
	updateContactData	allElements
	serviceOnline	allElements
	serviceOffline	allElements

[0683] The myContacts roleTemplate rt2 role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myContacts service through that method while mapped to this roleTemplate.

[0684]

	serviceOffline	allElements

[0685] The myContacts roleTemplate rt3 role gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myContacts service through that method while mapped to this roleTemplate:

[0686]

TABLE
myContacts Template rt3
	method	scope/name
	Query	onlyPublicElements
	updateContactData	allElements

[0687] The myContacts roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99. No methods/scope are in effect when accessing the myContacts service while mapped to this rt99 roleTemplate.

myContacts/Content

[0688] The content document is an identity centric document, with its content and meaning a function of the user identifier (puid) used to address the service. Accessing the document is controlled by the associated roleList document. The following table comprises a schema outline that illustrates the layout and meaning of the information found in the content document for the myContacts service.

[0690] The meaning of the attributes and elements shown in the table are set forth below, wherein in the syntax used in the table, boldface type corresponds to a blue node, and underlined type to a red node, as described above, and the minimum and maximum occurrence information (0, 1, unbounded) indicates whether an element or attribute is required or optional, and how many are possible.

[0691] The /myContacts (minOccurs=1 maxOccurs=1) element encapsulates the content document for this service. This element establishes a global cache scope for the service and contains other root-level system attributes for this instance of the service.

[0692] The /myContacts/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored, e.g., without generating an error.

[0693] The /myContacts/@instanceId (string minOccurs=0 maxOccurs=1) attribute is a unique identifier typically assigned to the root element of a service. It is a read-only element and assigned by the .NET My Services system when a user is provisioned for a particular service.

[0694] The /myContacts/contact (minOccurs=0 maxOccurs=unbounded) identifies a particular contact. The /myContacts/contact/@synchronize (string minOccurs=0 maxOccurs=1) attribute controls and/or enables synchronization of this contact node. When enabled, (e.g., value of “yes”), .NET My Services will attempt to keep the contact nodes synchronized with the reference data stored in the referenced PUID's myProfile default store, subject to permission. A value of “no” indicates that the system should not attempt to keep this contact node synchronized.

[0695] The /myContacts/contact/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0696] The /myContacts/contact/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0697] The /myContacts/contact/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node.

[0698] The /myContacts/contact/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid.

[0699] The /myContacts/contact/cat/@ref (anyURI minOccurs=0 maxOccurs=1) attribute references a category definition (<catDef/>) element using the rules outlined in the myCategories section of the present application.

These name nodes are not intended to be used for storing screen names or other electronic names, but rather to store a commonly used name for the entity. Names contain five parts and are meant to be combined in proper order, with spaces separating the parts and empty content parts excluded.

[0701] The /myContacts/contact/name/@changeNumber (minOccurs=0 maxOccurs=1) changeNumber attribute is designed to facilitate caching of the element and its descendants. This attribute is assigned to this element by the .NET My Services system. The attribute is read-only to applications. Attempts to write this attribute are silently ignored.

[0702] The /myContacts/contact/name/@id (minOccurs=0 maxOccurs=1) attribute is a globally unique ID assigned to this element by .NET My Services. Normally, .NET My Services will generate and assign this ID during an insertRequest operation, or possibly during a replaceRequest. Application software can override this ID generation by specifying the useClientIds attribute in the request message. Once an ID is assigned, the attribute is read-only and attempts to write it are silently ignored.

[0703] The /myContacts/contact/name/@creator (string minOccurs=0 maxOccurs=1) attribute identifies the creator in terms of userId, appId, and platformId of the node. The /myContacts/contact/name/cat (minOccurs=0 maxOccurs=unbounded) element is used to categorize the element that contains it by referencing a global category definition in either the .NET Categories service system document or an external resource containing category definitions, or by referencing an identity centric category definition in the content document of the .NET Categories service for a particular puid.

[0711] The /myContacts/contact/puid (string minOccurs=0 maxOccurs=1) element is used to specify a Passport Unique ID (PUID). The ID itself is in raw form, it is not encrypted in any way. The /myContacts/contact/specialDate (minOccurs=0 maxOccurs=unbounded) element encapsulates a special date that is important to this entity. Multiple special date nodes may exist. This is not a substitute for dates stored on an entity's myCalendar service, but rather intends to provide a convenient place to store a birth date, an anniversary date, and so on, because these dates are frequently imported into a contact record.

[0712] The /myContacts/contact/specialDate/@calendarType (string minOccurs=0 maxOccurs=1) field identifies an enumeration which determines the kind of calendar event this is, based on the following table, (which can be expanded):

myContacts/Domain Specific Methods

[0759] The myContacts service supports the standard methods query, insert, replace, delete, update, and the domain-specific methods updateContactData, serviceOnline and serviceOffline.

myDevices

[0760] The .NET Devices service is designed to store a combination of characteristics about primarily mobile communication devices, along with the carriers which provision those devices. This service is primarily designed to allow notifications, messages and other real-time communications to be delivered to a wide variety of devices on various transports.

myDevices/Roles

[0761] The myDevices service controls access by using the rt0, rt1, rt2, rt3 and rt99 roleTemplates, using the following scopes:

[0762]

scope allElements
<hs:scope id=7215df55-e4af-449f-a8e4-72a1f7c6a987>
	<hs:shape base=t>
	</hs:shape>
</hs:scope>
scope onlySelfElements
<hs:scope id=a159c93d-4010-4460-bc34-5094c49c1633>
	<hs:shape base=nil>
	<hs:include select=//*[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlySelfSubscriptionElements
<hs:scope id=b7f05a6d-75cd-4958-9dfb-f532ebb17743>
	<hs:shape base=nil>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>
scope onlyPublicElements
<hs:scope id=da025540-a0c0-470f-adcf-9f07e5a5ec8f>
	<hs:shape base=nil>
	<hs:include select=//*[cat//@ref=‘hs:public’]/>
	<hs:include select=//subscription[@creator=‘$callerId’]/>
	</hs:shape>
</hs:scope>

[0763] The myDevices roleTemplate rt0 role gives complete read/write access to the information within the content document of the service being protected through this roleTemplate. The following table illustrates the available methods and the scope in effect when accessing the myDevices service through that method while mapped to this roleTemplate:

[0764]

TABLE
Devices roleTemplate rt0
	method	scope/name
	Query	allElements
	Insert	allElements
	Replace	allElements
	Delete	allElements
	Update	allElements

[0765] The myDevices roleTemplate rt1 role gives complete read access to all information within the content document of the service being protected through this roleTemplate. Applications mapping to this role also have a limited ability to write to information in the content document. They may create nodes in any location, but may only change/replace, or delete nodes that they created. The following table illustrates the available methods and the scope in effect when accessing the myDevices service through that method while mapped to this roleTemplate:

[0766]

TABLE
myDevices roleTemplate rt1
	method	scope/name
	Query	allElements
	Insert	onlySelfElements
	Replace	onlySelfElements
	Delete	onlySelfElements

[0767] The myDevices roleTemplate rt2 role gives complete read access to the information within the content document of the service being protected through this roleTemplate. Applications mapping to this role have very limited write access and are only able to create and manipulate their own subscription nodes. The following table illustrates the available methods and the scope in effect when accessing the myDevices service through that method while mapped to this roleTemplate:

[0768]

TABLE
myDevices roleTemplate rt2
	method	scope/name
	Query	allElements
	Insert	onlySelfSubscriptionElements
	replace	onlySelfSubscriptionElements
	Delete	onlySelfSubscriptionElements

[0769] The myDevices roleTemplate rt3 role gives limited read access to information within the content document that is categorized as “public.” The following table illustrates the available methods and the scope in effect when accessing the myDevices service through that method while mapped to this roleTemplate:

[0770]

myDevices roleTemplate rt3
	method	scope/name
	Query	onlyPublicElements

[0771] The myDevices roleTemplate rt99 blocks access to the content document. Note that lack of a role in the roleList has the same effect as assigning someone to rt99.

myDevices/Content

[0772] The content document is an identity centric document, with its content and meaning a function of the user identifier (puid) used to address the service. Accessing the document is controlled by the associated roleList document. The following table comprises a schema outline that illustrates the layout and meaning of the information found in the content document for the myDevices service:
