Abstract

A method and apparatus for improving the performance of a CMS system configured for bursting is disclosed. The CMS may be configured to automatically scan the CMS for unused document fragments and “clean up” the repository by reinserting the unused document fragments back into a corresponding source document. Thus, embodiments of the invention do not rely on beforehand knowledge and policy setting as current approaches. Rather, an autonomous method is used to manage document fragments by detecting and reinserting unused fragments back into their original documents.

Claims

1. A computer-implemented method of fragment reconstitution in a content management system (CMS), comprising:

scanning a plurality of document fragments stored by the CMS, wherein each of the plurality of document fragments was burst from a corresponding source document, and wherein each of the plurality of document fragments is associated with a reconstitution policy, wherein the reconstitution policy specifies criteria for determining whether to reinsert a given one of the plurality of document fragments back into the corresponding source document;

reinserting at least one of the document fragments into the respective source document corresponding to the at least one document fragment, based on the respective reconstitution policy associated with the at least one document fragment, thereby producing an at least partially reconstituted source document; and

storing the partially reconstituted source document on a computer readable medium.

2. The method of claim 1, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum period of time that the at least one document fragment is stored in the CMS before being eligible for reinsertion.

3. The method of claim 1, wherein the at least one document fragment is reused by a plurality of corresponding source documents.

4. The method of claim 1, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum number of source documents that reference the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

5. The method of claim 1, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum peer document reuse percentage of the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

6. The method of claim 1, further comprising:

receiving a new source document to be stored in the CMS;

bursting, from the new source document, a first document fragment; and

associating the first document fragment with a reconstitution policy.

7. The method of claim 1, further comprising, specifying a minimum time period for the reinserted document fragment into the source document, wherein the minimum time period before the reinserted document fragment is eligible to be burst from the source document.

8. The method of claim 1, further comprising, sending a message to notify a document owner that the at least one document fragment has been reinserted into the corresponding source document.

9. A computer-readable storage medium containing a program which, when executed, performs an operation for fragment reconstitution in a content management system (CMS), the operation comprising:

scanning a plurality of document fragments stored by the CMS, wherein each of the plurality of document fragments was burst from a corresponding source document, and wherein each of the plurality of document fragments is associated with a reconstitution policy, wherein the reconstitution policy specifies criteria for determining whether to reinsert a given one of the plurality of document fragments back into the the corresponding source document; and

reinserting at least one of the document fragments into the respective source document corresponding to the at least one document fragment, based on the respective reconstitution policy associated with the at least one document fragment, thereby producing an at least partially reconstituted source document; and

storing the partially reconstituted source document on a computer readable medium.

10. The computer-readable storage medium of claim 9, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum period of time that the at least one document fragment is stored in the CMS before being eligible for reinsertion.

11. The computer-readable storage medium of claim 9, wherein the at least one document fragment is reused by a plurality of corresponding source documents.

12. The computer-readable storage medium of claim 9, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum number of source documents that reference the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

13. The computer-readable storage medium of claim 9, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum peer document reuse percentage of the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

14. The computer-readable storage medium of claim 9, wherein the operation further comprises:

receiving a new source document to be stored in the CMS;

bursting, from the new source document, a first document fragment; and

associating the first document fragment with a reconstitution policy.

15. The computer-readable storage medium of claim 9, wherein the operation further comprises, specifying a minimum time period for the reinserted document fragment into the source document, wherein the minimum time period before the reinserted document fragment is eligible to be burst from the source document.

16. The computer-readable storage medium of claim 9 wherein the operation further comprises, sending a message to notify a document owner that the at least one document fragment has been reinserted into the source document.

17. A system, comprising:

a processor; and

a memory containing a content management system (CMS) program which, when executed by the processor, for fragment reconstitution in the CMS, the operation comprising;

scanning a plurality of document fragments stored by the CMS, wherein each of the plurality of document fragments was burst from a corresponding source document, and wherein each of the plurality of document fragments is associated with a reconstitution policy, wherein the reconstitution policy specifies criteria for determining whether to reinsert a given one of the plurality of document fragments back into the corresponding source document; and

reinserting at least one of the document fragments into the respective source document corresponding to the at least one document fragment, based on the respective reconstitution policy associated with the at least one document fragment, thereby producing an at least partially reconstituted source document; and

storing the partially reconstituted source document on a computer readable medium.

18. The system of claim 17, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum period of time that the at least one document fragment is stored in the CMS before being eligible for reinsertion.

19. The system of claim 17, wherein the at least one document fragment is reused by a plurality of corresponding source documents.

20. The system of claim 17, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum number of source documents that reference the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

21. The system of claim 17, wherein the reconstitution policy associated with the at least one document fragment specifies at least a minimum peer document reuse percentage of the at least one document fragment in order to avoid reinsertion of the at least one source document fragment into the corresponding source document.

22. The system of claim 17, wherein the operation further comprises:

receiving a new source document to be stored in the CMS;

bursting, from the new source document, a first document fragment; and

associating the first document fragment with a reconstitution policy.

23. The system of claim 17, wherein the operation further comprises, specifying a minimum time period for the reinserted document fragment into the source document, wherein the minimum time period before the reinserted document fragment is eligible to be burst from the source document.

24. The system of claim 17, wherein the operation further comprises, sending a message to notify a document owner that the at least one document fragment has been reinserted into the source document.
