Abstract

A method and apparatus for dynamically managing data-type associations and relationships includes providing a first global data-type association ruleset including one or more predefined operational relationships between two or more applications, determining whether an updated global data-type association ruleset is available, and dynamically obtaining the updated global data-type association ruleset to facilitate modification of one or more predefined operational relationships between two or more applications locally installed on the client device.

Claims

1. In a client device, a method comprising:

providing a first master database, the master database including one or more predefined operational relationships between two or more applications;

determining whether an updated master database is available;

dynamically obtaining the updated master database to facilitate modification of one or more predefined operational relationships between two or more applications locally installed on the client device; and

generating a local database defining one or more local relationships between two or more independent applications installed on the client device to supplement the master database.

2. The method of claim 1, wherein generating a local database further comprises:

performing a first data-type association scan of the client device to identify one or more data associations between at least one originating application and at least one target application installed on the client device.

3. The method of claim 2, further comprising:

periodically performing additional data-type association scans to determine whether any additional local applications have been installed on the client device.

4. The method of claim 3, wherein at least a subset of the identified one or more data associations are dynamically modified as a result of one or more of the additional data-type association scans determining that at least one additional local application has been installed on the client device.

5. The method of claim 1, wherein generating a database further comprises:

automatically associating one or more data-types with one or more applications installed locally on the client without user confirmation.

6. The method of claim 1, wherein generating a database further comprises:

associating one or more data-types with one or more applications installed locally on the client after explicit user confirmation.

7. The method of claim 1, wherein the updated master database is obtained from a remote device.

8. The method of claim 1, wherein the updated master database prospectively reserves at least one new data-type for use by a preferred application independent of whether the preferred application is installed on the client device.

9. The method of claim 1, wherein the updated master database is obtained as a result of a comparison between the first master database and the updated master database.

10. The method of claim 1, wherein a data-type comprises one or more file extension and mime-type combinations.

11. An apparatus comprising:

a storage medium; and

a plurality of instructions stored in said storage medium to

provide a first master database, the master database including one or more predefined operational relationships between two or more applications,

determine whether an updated master database is available;

dynamically obtain the updated master database to facilitate modification of one or more predefined operational relationships between two or more applications locally installed on the client device; and

instructions stored in said storage medium to generate a local database defining one or more local relationships between two or more independent applications installed on the client device to supplement the master database.

12. The apparatus of claim 11, wherein the instructions to generate a local database further comprise instructions to perform a first data-type association scan of the client device to identify one or more data associations between at least one originating application and at least one target application installed on the client device.

13. The apparatus of claim 12, further comprising instructions stored in said storage medium to periodically perform additional data-type association scans to determine whether any additional local applications have been installed on the client device.

14. The apparatus of claim 13, wherein at least a subset of the identified one or more data associations are dynamically modified as a result of one or more of the additional data-type association scans determining that at least one additional local application has been installed on the client device.

15. The apparatus of claim 11, wherein the instructions to generate a local database further comprise instructions to automatically associate one or more data-types with one or more applications installed locally on the client without user confirmation.

16. The apparatus of claim 11, wherein the instructions to generate a local database further comprise instructions to associate one or more data-types with one or more applications installed locally on the client after explicit user confirmation.

17. The apparatus of claim 11, wherein the updated master database is obtained from a remote device.

18. The apparatus of claim 11, wherein the updated master database prospectively reserves at least one new data-type for use by a preferred application independent of whether the preferred application is installed on the client device.

19. The apparatus of claim 11, wherein the updated master database is obtained as a result of a comparison performed between the first master database and the updated master database.

20. The apparatus of claim 11, wherein a data-type comprises one or more file extension and mime-type combinations.

21. A computer system comprising:

at least one client device having a processor;

means for providing a first master database, the master database including one or more predefined operational relationships between two or more applications;

means for determining whether an updated master database is available;

means for dynamically obtaining the updated master database to facilitate modification of one or more predefined operational relationships between two or more applications locally installed on the client and

means for generating a local database defining one or more local relationships between two or more independent applications installed on the client device to supplement the master database.

22. The computer system of claim 21, wherein said means for dynamically obtaining the updated master database comprise network interface means for communicating across a communications network.
