Abstract

Systems and methods for managing data, such as metadata or non-metadata such as content. In one exemplary method, a composite document is received and it is determined whether the composite document contains at least one subdocument and if it does, the method captures metadata and/or content from the subdocument and stores the captured metadata and/or content for use in future searches (or an immediate search). The metadata and/or content from the composite document is typically combined together with information about the hierarchy of the subdocuments in the document. The type of information in metadata for one type of file differs from the type of information in metadata for another type of file. Other methods are described and data processing systems and machine readable media are also described.

Claims

1. A method performed by a data processing system, comprising:

receiving a composite document;

breaking the composite document into multiple subdocuments of a plurality levels of depth, the subdocuments having different file types;

individually indexing the content of the multiple subdocuments and adding the content to an indexed database;

capturing metadata from the multiple subdocuments, wherein the metadata describes the content of the subdocuments and independently storing the metadata of the subdocuments into a metadata database; and

,

searching the stored metadata using a search query, wherein the search is performed as the search query is being received.

2. The method of claim 1 wherein the method is a recursive process.

3. The method of claim 1 wherein the capturing of metadata is performed by a plurality of importer programs, each tailored for at least one particular file format.

4. The method of claim 1 wherein the metadata of the composite document forms a hierarchical structure.

5. The method of claim 1 wherein the capturing of metadata is performed for relevant subdocuments, wherein relevant subdocuments are specified by at least one of a position of a relevant subdocument in a presentation of the composite document and a frequency of occurrence of the relevant subdocument in the composite document.

6. The method of claim 1 wherein a first importer captures metadata from one portion of the composite document and a second importer captures metadata from another portion of the composite document, and wherein metadata is captured from a plurality of nested levels of subdocuments.

7. The method of claim 1 further comprising:

receiving a notification from an operating system element that a document has changed or been created or been deleted, and wherein the capturing is in response to the receiving of the notification.

8. The method of claim 1 further comprising:

determining a type of a subdocument having metadata and, in response to determining the type,

selecting a first software element from a group of software elements, wherein the first software element performs said capturing from the subdocument and a second software element, from the group, captures metadata from at least one portion of the composite document other than the subdocument.

25. The method of claim 1, wherein capturing metadata from the subdocuments comprises:

extracting one of the subdocuments into a temporary file with a first type, wherein the composite document has a second type different from the first type;

selecting a metadata importer based on the first type; and

capturing the metadata from the temporary file using the selected metadata importer.

28. The method of claim 1, further comprising:

receiving a command to delete a file;

determining that one of the subdocuments of the composite document is a copy of the file to be deleted;

performing a predetermined action in response to the determining.

29. The method of claim 28, wherein the predetermined action is one of notifying a user about the subdocument and deleting the one subdocument from the composite document.

34. The method of claim 1 wherein the searching is begun concurrently as the search query is entered and before entry of the search query is completed.

9. A non-transitory machine readable storage medium containing executable program instructions for causing a data processing system to perform a method of managing data, the method comprising:

receiving a composite document;

breaking the composite document into multiple subdocuments of a plurality levels of depth, the subdocuments having different file types;

individually indexing the content of the multiple subdocuments and adding the content to an indexed database;

capturing metadata from the multiple subdocuments, wherein the metadata describes the content of the subdocuments and independently storing the metadata of the subdocuments into a metadata database; and

searching the stored metadata using a search query, wherein the search is performed as the search query is being received.

10. The non-transitory machine readable storage medium of claim 9 wherein the method is a recursive process.

11. The non-transitory machine readable storage medium of claim 9 wherein the capturing of metadata is performed by a plurality of importer programs, each tailored for at least one particular file format.

12. The non-transitory machine readable storage medium of claim 9 wherein the metadata of the composite document forms a hierarchical structure.

13. The non-transitory machine readable storage medium of claim 9 wherein the capturing of metadata is performed for relevant subdocuments, wherein relevant subdocuments are specified by at least one of a position of a relevant subdocument in a presentation of the composite document and a frequency of occurrence of the relevant subdocument in the composite document.

14. The non-transitory machine readable storage medium of claim 9 wherein a first importer captures metadata from one portion of the composite document and a second importer captures metadata from another portion of the composite document, and wherein metadata is captured from a plurality of nested levels of subdocuments.

15. The non-transitory machine readable storage medium of claim 9 further comprising:

receiving a notification from an operating system element that a document has changed or been created or been deleted, and wherein the capturing is in response to the receiving of the notification.

16. The non-transitory machine readable storage medium of claim 9 further comprising:

determining a type of a subdocument having metadata and, in response to determining the type,

selecting a first software element from a group of software elements, wherein the first software element performs said capturing from the subdocument and a second software element from the group captures metadata from at least one portion of the composite document other than the subdocument.

26. The non-transitory machine readable storage medium of claim 9, wherein capturing metadata from the subdocuments comprises:

extracting one of the subdocuments into a temporary file with a first type, wherein the composite document has a second type different from the first type;

selecting a metadata importer based on the first type; and

capturing the metadata from the temporary file using the selected metadata importer.

30. The non-transitory machine readable storage medium of claim 9, further comprising:

receiving a command to delete a file;

determining that one of the subdocuments of the composite document is a copy of the file to be deleted;

performing a predetermined action in response to the determining.

31. The method of claim 30, wherein the predetermined action is one of notifying a user about the one subdocument and deleting the subdocument from the composite document.

35. The non-transitory machine readable storage medium of claim 9 wherein the searching is begun concurrently as the search query is entered and before entry of the search query is completed.

17. A data processing system comprising:

means for receiving a composite document;

means for breaking the composite document into multiple subdocuments of a plurality levels of depth, the subdocuments having different file types;

means for capturing metadata from the multiple subdocuments, wherein the metadata describes the content of the subdocuments and independently storing the metadata of the subdocuments into a metadata database; and
