Abstract

A system and method for describing content in a virtual content repository (VCR), comprising integrating a plurality of repositories into the VCR, storing a first schema in the VCR, wherein the first schema includes a first set of one or more properties, wherein the first schema is accessible through a logical namespace that encompasses the VCR, and wherein the first schema can describe the shape of the content.

Claims

1. A method for describing content in a virtual content repository (VCR), comprising:

integrating a plurality of repositories into the VCR;

storing a first schema in the VCR, wherein the first schema includes a first set of one or more properties;

wherein the first schema is accessible through a logical namespace that encompasses the VCR; and

wherein the first schema can describe the shape of the content.

2. The method of claim 1 wherein:

the first schema can inherit a second set of one or more properties from a second schema.

3. The method of claim 2 wherein:

the first schema can reside in a first repository;

the second schema can reside in a second repository; and

wherein the first repository and the second repository are of the plurality of repositories.

4. The method of claim 2 wherein:

the first schema resides in the VCR.

5. The method of claim 2 wherein:

the first schema can inherit from a second schema a role and/or a policy.

6. The method of claim 1 wherein:

a property includes a data type; and

wherein the data type is one of;

a basic type;

a choice;

a schema;

a link to content outside of the VCR;

an expression that evaluates to content within the VCR; and

a mapping to a database table or a view of a database.

7. The method of claim 1 wherein:

access to the first schema can be controlled by at least one role and/or at least one policy.

8. The method of claim 1 wherein:

the content can be instantiated based on the first schema.

9. The method of claim 8 wherein:

the content can inherit from the first schema at least one role and/or policy.

10. The method of claim 1 wherein the step of integrating includes:

implementing a service provider interface (SPI) that is compatible with the VCR.

11. A system for describing content, comprising:

a virtual content repository (VCR) to store the content;

a plurality of repositories integrated into the VCR;

a first schema stored in the VCR, wherein the first schema includes a first set of one or more properties;

wherein the first schema is accessible through a logical namespace that encompasses the VCR; and

wherein the first schema can describe the shape of the content.

12. The system of claim 11 wherein:

the first schema can inherit a second set of one or more properties from a second schema.

13. The system of claim 12 wherein:

the first schema can reside in a first repository;

the second schema can reside in a second repository; and

wherein the first repository and the second repository are of the plurality of repositories.

14. The system of claim 12 wherein:

the first schema resides in the VCR.

15. The system of claim 12 wherein:

the first schema can inherit from a second schema a role and/or a policy.

16. The system of claim 11 wherein:

a property includes a data type; and

wherein the data type is one of;

a basic type;

a choice;

a schema;

a link to content outside of the VCR;

an expression that evaluates to content within the VCR; and

a mapping to a database table or a view of a database.

17. The system of claim 11 wherein:

access to the first schema can be controlled by at least one role and/or at least one policy.

18. The system of claim 11 wherein:

the content can be instantiated based on the first schema.

19. The system of claim 18 wherein:

the content can inherit from the first schema at least one role and/or policy.

20. The system of claim 11, further comprising:

a service provider interface (SPI) that is compatible with the VCR implemented by the at least one repository.

21. A machine readable medium having instructions stored thereon that when executed by one or more processors cause a system to:

integrate a plurality of repositories into a virtual content repository (VCR);

store a first schema in the VCR, wherein the first schema includes a first set of one or more properties;

wherein the first schema is accessible through a logical namespace that encompasses the VCR; and

wherein the first schema can describe the shape of the content.

22. The machine readable medium of claim 21 wherein:

the first schema can inherit a second set of one or more properties from a second schema.

23. The machine readable medium of claim 22 wherein:

the first schema can reside in a first repository;

the second schema can reside in a second repository; and

wherein the first repository and the second repository are of the plurality of repositories.

24. The machine readable medium of claim 22 wherein:

the first schema resides in the VCR.

25. The machine readable medium of claim 22 wherein:

the first schema can inherit from a second schema a role and/or a policy.

26. The machine readable medium of claim 21 wherein:

a property includes a data type; and

wherein the data type is one of;

a basic type;

a choice;

a schema;

a link to content outside of the VCR;

an expression that evaluates to content within the VCR; and

a mapping to a database table or a view of a database.

27. The machine readable medium of claim 21 wherein:

access to the first schema can be controlled by at least one role and/or at least one policy.

28. The machine readable medium of claim 21 wherein:

the content can be instantiated based on the first schema.

29. The machine readable medium of claim 27 wherein:

the content can inherit from the first schema at least one role and/or policy.

30. The machine readable medium of claim 21, further comprising instructions that when executed cause the system to:

implement a service provider interface (SPI) that is compatible with the VCR.

31. A computer data signal embodied in a transmission medium, comprising:

a code segment including instructions to integrate a plurality of repositories into a virtual content repository (VCR);

a code segment including instructions to store a first schema in the VCR, wherein the first schema includes a first set of one or more properties;

wherein the first schema is accessible through a logical namespace that encompasses the VCR; and

wherein the first schema can describe the shape of the content.
