Abstract

Various technologies and techniques improve the updating of client content in a client/server arrangement. A client notification engine of a user interface subscribes to receive notifications from a central server side notification engine. The client notification engine polls the server side notification engine at a specified interval. The server side notification engine receives and aggregates notifications about and/or from one or more sources and aggregates them into a collection of relevant notifications. These notifications are sent to the client where the different subscriptions originated and are then used by the user interface in the client to update part of the content being displayed as appropriate.

Claims

1. A method for improving client-side content updates comprising:

sending a registration from a client-side notification engine of a communications application to a web server with a central notification engine to register for update notifications;

at a particular time interval, sending a polling request from the client-side notification engine to the central notification engine for polling whether the central notification engine has one or more update notifications identified with the registration from the client-side notification engine;

when the central notification engine has one or more notifications to report, receiving a notification response from the central notification engine wherein the notification response is an aggregation of updates from a first data store and a second data store, the updates comprising two or more of the following;

email, calendar, contacts, notes, or tasks;

when the central notification engine has no notifications to report, receiving a notification response from the central notification engine indicating that no updates have occurred.

2. The method of claim 1, wherein the notification response further includes a list of updated folders, the list identifying folders that have updated contents.

3. A computer-readable storage medium having computer-executable instructions for causing a computer to perform the steps recited in claim 1.

14. The method of claim 1, wherein the notification response further includes at least one voice mail notification.

15. The method of claim 1, wherein the notification response is represented in XML.

16. The method of claim 1, wherein the request to register for a plurality of update notifications further comprises information identifying a plurality of folders to monitor for changes.

17. The method of claim 1, wherein the central notification engine detects updates in a data store on a separate computer in order to generate update notifications.

18. The method of claim 1, wherein the notification response further includes a list of folders that contain updated information.

19. The method of claim 1, wherein the client-side notification engine is executed inside a web browser.

4. A computer-readable storage medium having computer-executable instructions for causing a computer to perform acts comprising:

at a web server computer, receiving a request from a client application to register for a plurality of notifications;

creating, at a back-end server computer, a condition advisor for at least a first folder in a particular set of folders, the condition advisor being operable to track a modified status for the first folder;

creating, at the back-end server computer, an item count advisor for at least a second folder in the particular set of folders, the item count advisor being operable to track a count associated with one or more items in the second folder;

creating, at the back-end server computer, an event queue for new notifications for at least a third folder in the particular set of folders, the event queue being operable to store at least a portion of information about new notifications that are received;

the back-end server communicating with the at least one data store at specified data gathering time intervals to update the condition advisor, item count advisor, and event queue as a set of data in the data store changes;

the web server receiving a polling request from the client application after a specified polling interval passes for polling whether there are one or more change notifications to report when at least a portion of content in the at least one data store has changed for the notifications;

checking at least the condition advisor and item count advisor to determine whether there are one or more notifications to report to the client application;

generating a notification response that includes at least a portion of the information in the condition advisor, item count advisor, and event queue wherein the notification response contains a reduced amount of information determined by a current context of a user; and

transmitting the notification response to the client application.

5. The computer-readable medium of claim 4, wherein the checking further comprises checking the event queue as part of determining whether there are one or more notifications to report.

6. The computer-readable medium of claim 4, wherein the item count advisor for the second folder is operable to track a number of unread items in the second folder.

7. The computer-readable medium of claim 4, wherein item count advisor for the second folder is based upon a total number of items in the second folder.

8. The computer-readable medium of claim 4, wherein the condition advisor for the first folder is based upon whether the first folder has a portion of content that has been changed.

9. The computer-readable medium of claim 4, wherein the new notifications are selected from the group consisting of an email message, a fax message, a voice mail message, and a reminder message.

10. The computer-readable medium of claim 4, wherein the first folder and the second folder are a same folder.

11. The computer-readable medium of claim 4, wherein the client application is a browser based application.

12. A system for facilitating content updates in an application comprising:

a server having a processor and a memory communicatively coupled to the processor and storing executable instructions, the server being a web server operable to communicate with a client over a network via a markup language based protocol;

the server being further operable to communicate with at least one data store over a network; and

wherein the server provides a central notification engine service implemented by the processor executing instructions stored on the memory, the central notification engine service being operable to perform a set of operations through the processor and comprising;

receiving a request from a client application located on the client to register for a plurality of notifications;

creating at the server an advisor for each of a plurality of folders, the advisor being operable to track whether a particular set of data in the data store has changed;

communicating with at least one data store at specified data gathering time intervals to update the advisor for each of the folders as a set of data in the data store changes;

receiving a polling request from the client application after a specified polling interval passes for polling whether there are one or more notifications to report when at least a portion of the particular set of data in the data store has changed for the notifications;

checking the advisor for each of the folders to determine whether there are two or more notifications to report to the client application;

if there are two or more notifications to report, combining the two or more notifications at the server, and

reporting the combined notification to the client application in a single response.

13. The system of claim 12, wherein the server is further operable to create an item count advisor for each of the folders and a condition advisor for each of the folders.

20. The method of claim 12, wherein the combining the two or more notifications at the server combines at least one email notification and at least one contacts notification.
