Abstract

A method for integrating a plurality of content repositories into a virtual content repository (VCR), comprising providing credential information to each one of said plurality of content repositories, receiving authorization information from each one of said plurality of content repositories, wherein the authorization information indicates whether or not an authorization procedure succeeded, integrating into the VCR each one of said plurality of content repositories whose authorization information indicates successful authorization, and wherein each one of said plurality of content repositories exposes a first set of services to enable its integration into the VCR.

Claims

1. A method of organizing content stored in a plurality of content repositories into a virtual content repository (VCR) namespace, the method comprising:

providing a first identifier that uniquely identifies at least one node representing content within one of the plurality of content repositories;

providing a second identifier that uniquely identifies the at least one node within the namespace; and

organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository;

thereby providing the virtual content repository comprising a logical representation of the plurality of content repositories such that the plurality of content repositories behave as a single content repository.

2. The method of claim 1 wherein providing a second identifier that uniquely identifies the at least one node within the namespace comprises:

providing a path that uniquely identifies the at least one node within the namespace.

3. The method of claim 1 wherein organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository comprises:

organizing hierarchically the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository.

4. The method of claim 1 further comprising:

associating the at least one node with at least one property.

5. The method of claim 4 wherein associating the at least one node with at least one property comprises:

associating the at least one node with an association between a name and at least one value.

6. The method of claim 4 wherein associating the at least one node with at least one property comprises:

associating the at least one node with at least one property definition.

7. The method of claim 6 wherein associating the at least one node with at least one property definition comprises:

associating the at least one node with at least one property definition that specifies for a property at least one of the following attributes;

property choices;

a reference;

a data type;

whether the property is mandatory;

whether the property is multi-valued;

whether the property is primary;

whether the property is read-only; and

whether the property is restricted.

8. The method of claim 6 wherein associating the at least one node with at least one property definition comprises:

associating the at least one node with at least one property definition for each property associated with the at least one node.

9. The method of claim 1 wherein organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository comprises:

organizing identifiers in the namespace such that the at least one node can be hierarchically related to other nodes in the VCR.

10. The method of claim 1 organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository comprises:

organizing identifiers in the namespace based at least in part upon a set of services exposed by each one of the plurality of content repositories to enable its integration into a virtual content repository (VCR).

11. A machine-readable medium carrying one or more sequences of instructions for organizing content stored in a plurality of content repositories into a virtual content repository (VCR) namespace, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:

providing a first identifier that uniquely identifies at least one node representing content within one of the plurality of content repositories;

providing a second identifier that uniquely identifies the at least one node within the namespace; and

organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository;

thereby providing the virtual content repository comprising a logical representation of the plurality of content repositories such that the plurality of content repositories behave as a single content repository.

12. The machine-readable medium as recited in claim 11 wherein the instructions for carrying out the step of providing a second identifier that uniquely identifies the at least one node within the namespace include instructions for carrying out the step of:

providing a path that uniquely identifies the at least one node within the namespace.

13. The machine-readable medium as recited in claim 11 wherein the instructions for carrying out the step of organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository include instructions for carrying out the step of:

organizing hierarchically the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository.

14. The machine-readable medium as recited in claim 11 further comprising instructions for carrying out the step of:

associating the at least one node with at least one property.

15. The machine-readable medium as recited in claim 14 wherein the instructions for carrying out the step of associating the at least one node with at least one property include instructions for carrying out the step of:

associating the at least one node with an association between a name and at least one value.

16. The machine-readable medium as recited in claim 14 wherein the instructions for carrying out the step of associating the at least one node with at least one property include instructions for carrying out the step of:

associating the at least one node with at least one property definition.

17. The machine-readable medium as recited in claim 16 wherein the instructions for carrying out the step of associating the at least one node with at least one property definition include instructions for carrying out the step of:

associating the at least one node with at least one property definition that specifies for a property at least one of the following attributes;

property choices;

a reference;

a data type;

whether the property is mandatory;

whether the property is multi-valued;

whether the property is primary;

whether the property is read-only; and

whether the property is restricted.

18. The machine-readable medium as recited in claim 16 wherein the instructions for carrying out the step of associating the at least one node with at least one property definition include instructions for carrying out the step of:

associating the at least one node with at least one property definition for each property associated with the at least one node.

19. The machine-readable medium as recited in claim 11 wherein the instructions for carrying out the step of organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository include instructions for carrying out the step of:

organizing identifiers in the namespace such that the at least one node can be hierarchically related to other nodes in the VCR.

20. The machine-readable medium as recited in claim 11 wherein the instructions for carrying out the step of organizing the second identifier in the namespace with at least one other identifier that uniquely defines another node within the namespace, the node representing other content in at least one other content repository include instructions for carrying out the step of:

organizing identifiers in the namespace based at least in part upon a set of services exposed by each one of the plurality of content repositories to enable its integration into a virtual content repository (VCR).
