Abstract

A method, system and apparatus for detecting and resolving conflict resolution in a synchronization framework. In this regard, a synchronization framework which has been configured in accordance with the present invention can include a synchronization engine configured for coupling to an application utilizing a data set subject to synchronization with another application. The framework further can include a synchronization adapter communicatively linked to the synchronization engine. Finally, the framework can include conflict detection and resolution logic disposed within the synchronization framework and configured for communication with one of the synchronization engine and the synchronization adapter.

Claims

1. A synchronization framework comprising:

a synchronization engine configured for coupling to an application utilizing a data set subject to synchronization with another application;

a synchronization adapter communicatively linked to said synchronization engine; and

,

conflict detection and resolution logic disposed within the synchronization framework and configured for communication with one of said synchronization engine and said synchronization adapter.

2. The synchronization framework of claim 1, wherein said conflict detection and resolution logic further comprises a set of rules governing conflict resolution for data sets passed to said synchronization engine.

3. The synchronization framework of claim 2, wherein said rules comprise a static mapping of conflict types to conflict resolutions.

4. The synchronization framework of claim 2, wherein said rules comprise a dynamic mapping of conflict types to conflict resolutions.

5. The synchronization framework of claim 2, wherein said set of rules further a configuration for extension by said application.

6. The synchronization framework of claim 1, wherein the synchronization framework implements a SYNCML framework.

7. In a synchronization framework, a conflict detection and resolution method comprising the steps of:

receiving an update from a client application for application in a server application;

detecting and resolving conflicts for said received update in the synchronization framework; and

,

selectively applying said update in said server application. And altering the updates to be sent to the client if necessary, based on the outcome of the conflict resolution.

8. The method of claim 7, wherein said detecting step comprises the step of determining whether a data set implicated by said received update exists in said server application.

9. The method of claim 7, wherein said detecting step comprises the step of determining whether a data set implicated by said received update in said server application has been modified by said server application.

10. The method of claim 7, wherein said resolving step comprises the steps of:

determining a conflict type for said update;

selecting a conflict resolution based upon said determined conflict type; and

,

performing said selected conflict resolution; and

,

applying said update subsequent to performing said selected conflict resolution.

11. The method of claim 10, wherein said determining step comprises the step of determining a conflict type for said update selected from the group consisting of replace-replace, replace-delete, delete-replace, replace-add, add-replace, add-add, add-delete, delete-add, and delete-delete.

12. The method of claim 10, wherein said selecting step comprises the step of selecting a conflict resolution based upon said determined conflict type wherein said conflict resolution is selected from the group consisting of latest wins, client wins, server wins, update wins, delete wins, local wins, remote wins, duplicate, merge. merge else duplicate, no resolution, defer, error, and already exists.

13. The method of claim 7, further comprising the step of modifying an update to be sent to said client application if it is determined that a resolved one of said conflicts for said received update requires a modification to an update to be sent to said client.

14. A machine readable storage having stored thereon a computer program for conflict detection and resolution in a synchronization framework, the computer program comprising a routine set of instructions which when executed by a machine causes the machine to perform the steps of:

receiving an update from a client application for application in a server application;

detecting and resolving conflicts for said received update in the synchronization framework; and

,

selectively applying said update in said server application.

15. The machine readable storage of claim 14, wherein said detecting step comprises the step of determining whether a data set implicated by said received update exists in said server application.

16. The machine readable storage of claim 14, wherein said detecting step comprises the step of determining whether a data set implicated by said received update in said server application has been modified by said server application.

17. The machine readable storage of claim 14, wherein said resolving step comprises the steps of:

determining a conflict type for said update;

selecting a conflict resolution based upon said determined conflict type; and

,

performing said selected conflict resolution; and

,

applying said update subsequent to performing said selected conflict resolution.

18. The machine readable storage of claim 17, wherein said determining step comprises the step of determining a conflict type for said update selected from the group consisting of replace-replace, replace-delete, delete-replace, replace-add, add-replace, add-add, add-delete, delete-add, and delete-delete.

19. The machine readable storage of claim 17, wherein said selecting step comprises the step of selecting a conflict resolution based upon said determined conflict type wherein said conflict resolution is selected from the group consisting of latest wins, client wins, server wins, update wins, delete wins, local wins, remote wins, duplicate, merge. merge else duplicate, no resolution, defer, error, and already exists.

20. The machine readable storage of claim 17, further comprising an additional set of instructions which when executed by the machine causes the machine to perform an additional step of modifying an update to be sent to said client application if it is determined that a resolved one of said conflicts for said received update requires a modification to an update to be sent to said client.
