Abstract

A declarative mechanism is used to manage large documents within a repository. The large documents are sectioned into subdocuments that are linked together by a parent document. The combination of the parent document and subdocument is referred to as a compound document. There are multiple options for configuring rules to break up a source document into a compound document and naming the subdocuments. The compound documents may be queried using statements that treat the compound document as a single XML document, or the parent document of a subdocument may be queried and treated independently. Access control and versioning can be applied at the finer granularity of the subdocument.

Claims

1. A computer implemented method comprising:

accessing compound document declarations that specify how to section a given XML document into subdocuments of a compound document;

generating a compound document that includes a parent document and a plurality of subdocuments of said parent document; and

wherein generating said compound document includes applying said compound document declarations to a source XML document to generate said parent document and said plurality of subdocuments of said parent document.

2. The computer-implemented method of claim 1, wherein said compound document declarations are included in an XML schema document that is referenced by said source XML document.

3. The computer-implemented method of claim 1,

wherein the step of generating said compound document includes storing said parent document and said plurality of subdocuments in a repository that stores resources;

wherein said repository associates resources with one or more resource configurations that specify how said repository processes said resources; and

wherein said one or more resource configurations include said compound document declarations.

4. The computer-implemented method of claim 1, wherein said compound document declarations include one or more XPath expressions that identify content in said given XML document that comprises a given subdocument.

5. The computer-implemented method of claim 1, wherein said compound document declarations include a certain instruction that specifies how to generate at least one of a subdocument name or subdocument resource path.

6. The computer-implemented method of claim 5, wherein said certain instruction conforms to XPath.

7. The computer-implemented method of claim 1, wherein generating a compound document includes generating within said parent document a link to each subdocument of said plurality of subdocuments.

8. The computer-implemented method of claim 7, wherein generating within said parent document a link includes generating within said parent document a link to each subdocument according to a certain instruction that indicates that said link should be a hard, weak, or symbolic link.

10. The computer-implemented method of claim 1, wherein said statement includes an expression that references the parent document and represents an expansion said parent document.

11. The computer-implemented method of claim 1, wherein said expression includes an operator based on said parent document.

13. The computer-implemented method of claim 1, wherein said statement includes an expression that references the parent document and represents an expansion of said parent document.

14. The computer-implemented method of claim 1, wherein said expression includes an operator based on said parent document.

15. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 1.

16. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 2.

17. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 3.

18. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 4.

19. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 5.

20. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 6.

21. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 7.

22. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 8.

24. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 10.

25. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 11.

27. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 13.

28. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 14.

9. A computer-implemented method comprising,

storing within a repository a compound document that includes:

a parent document,

a plurality of subdocuments of said parent document,

said parent document including for each subdocument of said plurality of subdocuments, a link to said each subdocument;

receiving a statement that requests at least a portion of said compound document; and

in response to receiving said statement, expanding at least one link of a certain subdocument of said plurality of subdocuments by replacing the link with content of said certain subdocument.

23. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 9.

12. A computer-implemented method comprising,

storing within a repository a compound document that includes:

a parent document,

a plurality of subdocuments of said parent document,

said parent document including for each subdocument of said plurality of subdocuments, a link to said each subdocument;

said repository receiving a statement that specifies a change to content of said compound document, wherein said statement does not reference any subdocument of said plurality of subdocument;

wherein said content is in a certain subdocument of said plurality of subdocument;

in response to receiving said statement, changing said subdocument.

26. A computer-readable medium carrying one or more sequences of instructions which, when executed by one or more processors, causes the one or more processors to perform the method recited in claim 12.
