Abstract

A system, method and computer program product for exchanging data between a client and information sources via a server. The invention operates by obtaining data objects from a plurality of sources, wherein the data objects have native data formats specific to the sources. The data objects are converted to a common data format, and are then transmitted to the client. At the client, the data objects are modified. The modified data objects are compliant with the common data format. The modified data objects are transmitted to the server, where they are converted to the native data formats specific to the sources associated therewith. Then, the converted modified data objects are transmitted to the associated sources.

Claims

1-16. -16. (canceled)

17. A method of synchronizing a client with information sources via a server, comprising:

(1) querying a source to obtain first information;

(2) transmitting said first information to a client;

(3) receiving second information from said client, said second information including at least some modifications of said first information;

(4) re-querying said source to obtain third information;

(5) comparing said first information to said third information; and

(6) if said first information corresponds to said third information, then updating said source with said second information.

18. The method of claim 17, further comprising:

(7) if said first information does not correspond to said third information, then implementing a conflict resolution procedure.

19. The method of claim 18, wherein said conflict resolution procedure dictates that said source should be updated with said second information.

20. The method of claim 18, wherein said conflict resolution procedure dictates that said source should not be updated with said second information.

21. The method of claim 18, wherein said conflict resolution procedure dictates that a user should be queried for instructions on resolving said conflict.

22. The method of claim 18, wherein said first information is cached in said client.

23. The method of claim 18, wherein said first information is cached in said server.

24. A computer program product having control logic stored therein, said control logic enabling a computer to synchronize a client with information sources via a server, said control logic comprising:

means for enabling a computer to query a source to obtain first information;

means for enabling a computer to transmit said first information to a client;

means for enabling a computer to receive second information from said client, said second information including at least some modifications of said first information;

means for enabling a computer to re-query said source to obtain third information;

means for enabling a computer to compare said first information to said third information; and

means for enabling a computer to update said source with said second information if said first information corresponds to said third information.

25. The computer program product of claim 24, said control logic comprising:

means for enabling a computer to implement a conflict resolution procedure if said first information does not correspond to said third information.

26. The computer program product of claim 25, wherein said conflict resolution procedure dictates that said source should be updated with said second information.

27. The computer program product of claim 25, wherein said conflict resolution procedure dictates that said source should not be updated with said second information.

28. The computer program product of claim 25, wherein said conflict resolution procedure dictates that a user should be queried for instructions on resolving said conflict.

29. The computer program product of claim 24, wherein said first information is cached in said client.

30. The computer program product of claim 24, wherein said first information is cached in said server.

31. A system to synchronize a client with information sources via a server, comprising:

means for querying a source to obtain first information;

means for transmitting said first information to a client;

means for receiving second information from said client, said second information including at least some modifications of said first information;

means for re-querying said source to obtain third information;

means for comparing said first information to said third information; and

means for updating said source with said second information if said first information corresponds to said third information.

32. The system of claim 31, further comprising:

means for implementing a conflict resolution procedure if said first information does not correspond to said third information.
