Abstract

Access control data is transcoded or translated into a unified format. The unified format is acceptable and extensible so that other control languages can be transcoded into the unified format. Rights management information may be converted to unified storage metadata for use in a unified storage system. The construction of a data object that contains data and rights management information comprises transcoding both the original data to the unified storage format as well as transcoding the rights management information from any of a number of platforms to the rights management format used by the unified storage platform. Transcoding may occur in a transacted environment so that failures to complete will not degrade or lose data and rollback is possible if the process fails.

Claims

1. A method of transcoding and storing rights management information, comprising:

transcoding rights management information into an intermediate or universal format; and

storing the transcoded rights management information in a storage device.

2. The method of claim 1, wherein the intermediate or universal format is based on a source format and a target format.

3. The method of claim 1, wherein transcoding the rights management information comprises identifying schema that defines common characteristics from the source format and a target format.

4. The method of claim 3, wherein the schema comprises extensible rights management language.

5. The method of claim 1, wherein the storage device comprises unified storage.

6. The method of claim 1, wherein the transcoded rights management information comprises unified rights management information and unified storage metadata.

7. The method of claim 1, further comprising receiving data protected by the rights management information, transcoding the data, and storing the transcoded data in the storage device with the transcoded rights management information.

8. A rights management system, comprising:

a transcoder that receives rights management information and transcodes the rights management information into an intermediate or universal format; and

unified storage for storing the transcoded rights management information.

9. The system of claim 8, wherein the received rights management information is in a source format, and the intermediate or universal format is based on the source format and a target format.

10. The system of claim 8, wherein the transcoder identifies schema that defines common characteristics from a source format and a target format.

11. The system of claim 10, wherein the schema comprises extensible rights management language.

12. The system of claim 8, wherein the transcoded rights management information comprises unified rights management information and unified storage metadata.

13. The system of claim 8, wherein the transcoder receives data protected by the rights management information, transcodes the data, and stores the transcoded data in the unified storage with the transcoded rights management information.

14. A transcoder that transcodes rights management information into an intermediate or universal format, and provides the transcoded rights management information to unified storage.

15. The transcoder of claim 14, wherein the transcoder is adapted to receive the rights management information in a source format.

16. The transcoder of claim 15, wherein the intermediate or universal format is based on the source format and a target format.

17. The transcoder of claim 14, wherein the transcoder identifies schema that defines common characteristics from a source format and a target format.

18. The transcoder of claim 14, wherein the schema comprises extensible rights management language.

19. The transcoder of claim 14, wherein the transcoded rights management information comprises unified rights management information and unified storage metadata.

20. The transcoder of claim 14, wherein the transcoder receives data protected by the rights management information, transcodes the data, and stores the transcoded data in the unified storage with the transcoded rights management information.
