Abstract

Described is a schema-based notification platform that provides regularized notification handling including user control and normalization of the operation of policies across different information types and contexts. Information-service schemas and services are combined to build a content-sensitive and context-sensitive information service to communicate information to recipient devices of users that subscribe to those services. An information agent service collects the information, and based on various criteria, determines if, when, and how to send and render the information, and to which subscribing client device or devices. The set of schemas include a notification schema that represents the subscription of a service to an information source and details about that information, and a device schema that represents information about user devices. The information agent service accesses criteria including user preferences and user contextual information, including presence information, location information, and schedule information along with people and groups data and extended-context data. Preferences about subscriptions and information handling policies may be stored and used at notification sources or in more central preference encodings. Access to multiple preferences is maintained, and a user interface is provided that allows users to inspect and control multiple subscriptions in one conceptual place.

Claims

1. In a computer network, a method comprising,

receiving a notification directed to a client from an information source, the notification regularized according to a notification schema representing properties of a subscription to the information source including message handling preferences, and

determining whether the user should receive the notification based on user preference data and context data, the user preference data regularized according to a preferences schema, and if so, determining a selected device to receive the notification and sending the notification to the selected device,

wherein the notification is received at an information agent of the client and the notification schema and the preferences schema are used by the information agent to provide normalized handling of the notification received from the information source by processing or modifying initial values for properties represented by the notification schema based on the user preference data represented by the preferences schema.

2. The method of claim 1, further comprising, obtaining information about the selected device from a device service, and modifying data of the notification based on the information about the selected device before sending the notification output to the selected device.

3. The method of claim 2 wherein the device service provides the information about the selected device in a data structure regularized according to a device schema.

4. The method of claim 1, further comprising, accessing the context data from at least one service, the context data regularized according to at least one of a context schema, a presence schema, a location schema and a schedule schema.

5. The method of claim 1 wherein the user preference data is regularized according to at least one of a source preference schema and a main preference schema.

6. The method of claim 5 further comprising, before sending the notification output to the selected device, modifying data of the notification based on main preference data regularized according to the main preference schema.

7. The method of claim 1, further comprising, receiving the context data regularized according to at least one of an extended context schema, a people and groups schema, and a client computing context schema.

8. The method of claim 1 wherein it is determined that the user should not receive the notification based on the user preference data and context data, and further comprising, discarding the notification.

9. The method of claim 1 wherein it is determined that the user should not receive the notification based on user preference data and context data, and further comprising, storing the notification.

10. The method of claim 9, further comprising, performing a later determination on whether the user should receive the notification based on user preference data and context data, and if the later determination indicates the user should receive the notification, determining a selected device to receive the notification and sending the notification to the selected device.

11. The method of claim 1 wherein the notification comprises a message emitted by the information source that accompanies other communicated data.

12. The method of claim 1 wherein the notification includes rendering and fidelity information, and wherein determining a selected device comprises, evaluating the rendering and fidelity information ability with respect to available devices.

13. The method of claim 1 wherein a device that is not currently available is selected as the selected device, and further comprising, waiting for the selected device to be available before sending the notification.

14. The method of claim 1 wherein a device that is currently available is selected as the selected device, and further comprising, modifying content in the notification into an approximate version of the content before sending the notification.

15. The method of claim 1 wherein the notification comprises multiple types or components of content for rendering, and further comprising, determining capabilities of the selected device, and modifying the notification content based on capabilities of the selected device before sending the notification to the selected device.

16. The method of claim 1 wherein the notification includes rendering and fidelity information, and wherein determining a selected device comprises, evaluating the rendering abilities of available devices and available bandwidth data for sending the notification.

17. A computer-readable-storage medium having computer executable instructions comprising:

receiving a notification directed to a client from an information source, the notification regularized according to a notification schema representing properties of a subscription to the information source including message handling preferences;

accessing user preference data and context data to obtain criteria for sending the notification to the client, the user preference data regularized according to a preferences schema, and sending the notification to the client based on the criteria,

wherein the notification is received at an information agent of the client and the notification schema and the preferences schema are used by the information agent to provide normalized handling of the notification received from the information source by processing or modifying initial values for properties represented by the notification schema based on the user preference data represented by the preferences schema.

18. The computer-readable-storage medium of claim 17 wherein the criteria indicates that the notification should be sent to a particular client device.

19. The computer-readable-storage medium of claim 17 wherein the criteria indicates that the notification should be modified to correspond to a capability of a particular client device.

20. The computer-readable-storage medium of claim 17 wherein the criteria indicates that the notification should be preserved for later sending, and wherein sending the notification to the client comprises transmitting the notification to the client at a later time.

21. In a computer network, a method comprising:

receiving a notification from an information source at an information agent of a client, the notification regularized according to a notification schema representing properties of a subscription to the information source including message handling preferences; and

determining whether to send the notification to a user based on user preference data and context data, the user preference data regularized according to a preferences schema,

wherein the notification schema and the preferences schema are used by the information agent to provide normalized handling of the notification received from the information source by processing or modifying initial values for properties represented by the notification schema based on the user preference data represented by the preferences schema.

22. The method of claim 21, wherein the context data is regularized according to at least one of a context schema, a presence schema, a location schema, and a schedule schema.

23. The method of claim 21, wherein the context data is regularized according to at least one of an extended context schema, a people and groups schema, and a client computing context schema.

24. The method of claim 21, wherein the user preference data is regularized according to at least one of a source preference schema and a main preference schema.

25. The method of claim 24, further comprising modifying the notification based on main preference data regularized according to the main preference schema.

26. The method of claim 21, further comprising determining whether to send the notification based on the user preference data, and selecting a device to receive the notification if it is determined that the notification is to be sent.

27. The method of claim 26, further comprising modifying content of the notification based on capabilities of the selected device.
