Abstract

A system, method and apparatus for propagating data change notifications are provided. The system comprises a computing device in communication with an intermediation server via a network, the intermediation server in communication with an originating content server. A data change notification is received at the computing device from the intermediation server, the data change notification comprising an indication that a change has occurred to data at the originating content server. The data change notification is stored in a destination location at the computing device. The destination location is checked for data change notifications; and, when the data change notification is found, an indicator is controlled to indicate that a change has occurred to the data.

6. The method of claim 5, wherein said portion of said data structure is displayed in a representation of said data structure at a display device associated with said computing device.

7. The method of claim 6, wherein said data structure comprises HTML data, said embedded application comprises a java applet embedded in said HTML data, and said indicator comprises an icon displayed within said HTML data, such that only said indicator within said HTML data is updated rather than all of said HTML data.

8. The method of claim 1, wherein said data change notification further comprises at least a portion of said data.

9. The method of claim 8, further comprising causing a link to said least a portion of said data at said computing device to retrieve said least a portion of said data from said destination location rather than said originating content server when said link is actuated.

11. The method of claim 1, wherein said indicator comprises at least one of a visual indicator, an aural indicator, a mechanical indicator, a vibrating indicator, an LED (light emitting diode), a speaker, and a representation of said indicator at a display device associated with said computing device.

10. The method of 1, wherein said indicator is further controlled to expire after a given time period.

12. A computing device for propagating data change notifications, comprising:

a processing unit interconnected with a memory device and a communication interface, said communication interface for communicating with an intermediation server via a network, said processing unit enabled to;

receive a data change notification from said intermediation server, said data change notification comprising an indication that a change has occurred to data at an originating content server;

store said data change notification in a destination location at said computing device;

check said destination location for said data change notifications; and

, when said data change notification is found,

control an indicator to indicate that a change has occurred to said data.

13. The computing device of claim 12, wherein said destination location comprises at least one of a location in said memory device, a cache, and a location in a memory structure.

14. The computing device of claim 12, wherein said destination location is checked for said data change notifications via at least one of an application, and a java applet.

15. The computing device of claim 12, wherein said destination location is checked for said data change notifications via an embedded application embedded in a data structure for tracking said data.

16. The computing device of claim 15, wherein said indicator comprises a portion of said data structure, such that only said portion is updated when said data change notification is found.

17. The computing device of claim 16, wherein said portion of said data structure is displayed in a representation of said data structure at a display device associated with said computing device.

18. The computing device of claim 17, wherein said data structure comprises HTML data, said embedded application comprises a java applet embedded in said HTML data, and said indicator comprises an icon displayed within said HTML data, such that only said indicator within said HTML data is updated rather than all of said HTML data.

19. The computing device of claim 12, wherein said data change notification further comprises at least a portion of said data.

20. The computing device of claim 19, wherein said processing unit is further enabled to cause a link to said least a portion of said data at said computing device to retrieve said least a portion of said data from said destination location rather than said originating content server.

22. The computing device of claim 12, wherein said indicator comprises at least one of a visual indicator, an aural indicator, a mechanical indicator, a vibrating indicator, an LED (light emitting diode), a speaker, and a representation of said indicator at a display device associated with said computing device.
