Abstract

Particularly, a system and method are disclosed that enable an author of a subsection of a document quickly to locate referenced information in other parts of the document or different documents prepared by other authors and then incorporate that information in their own document. An author tags information in their document that other authors might wish to import. Each time the document is updated, or as requested by the author, the author'"'"'s tags and other tags that reference information that is importable by default (e.g., section headings, figures, tables) are exported to a tag repository that is accessible to all other authors. The tag repository also holds the tags generated by other authors from different documents. Using information finding/linking programs any of the authors can search the tag repository and select tags corresponding to information they would like to import into their own documents. The information can be imported by reference, by hypertext link, or by simple copying, among other techniques.

Claims

1. A method performed on a computer for linking data in a document set including a plurality of books, comprising the steps of;

tagging an information unit (iunit) from a first book with a tag that provides information about the iunit that includes a semantic attribute and a unique identifier;

exporting the tag to a tag repository; and

selecting the tag from the tag repository to request importation of the iunit to a second book.

2. The method of claim 1, wherein the exporting step is only performed by an author of the first book.

3. The method of claim 1, wherein the semantic information comprises a meaningful description provided by an author of the first book, the semantic information being viewable and searchable in the tag repository to enable an iunit of a desired semantic type to be selected for importation in the selecting step.

4. The method of claim 3, wherein each book has a respective set of authors and comprises a self-contained unit of document administration.

5. The method of claim 4, wherein each book comprises at least one document, each including one or more document units.

6. The method of claim 5, wherein each document unit corresponds to a respective computer file.

7. The method of claim 6, wherein the identifier uniquely identifies the document unit, document and book with which the iunit is associated.

8. The method of claim 7, wherein the tag is stored in a doctag file addressed by an associated doctag URL;

such that the iunit is accessed for importation to the second book via the doctag URL.

9. The method of claim 8, wherein the doctag file is stored on a network node that hosts the first book.

10. The method of claim 9, wherein the network node comprises:

a set of document URLs;

each of the document URLs being associated with a respective document within the first book and identifying a second file including a list of docunit URLs, each of which is associated with a respective docunit included within the respective document; and

each of the docunit URLs identifying a respective third file including a list of the doctag URLs associated with respective doctag files included within the respective docunit.

11. The method of claim 10, wherein:

the tag repository comprises a list of domain URLs, each identifying a respective fourth file including the set of document URLs associated with documents composing a corresponding book within a document set; and

the network node comprises;

one copy of the tag repository; and

the second, third, and fourth files associated with the book hosted on that node.

12. The method of claim 7, wherein the iunits associated with a particular book are stored across at least one networked node.

13. The method of claim 4, wherein the tag repository comprises a single, global tag repository stored on a single computer.

14. The method of claim 4, wherein:

the tag repository is distributed across a plurality of networked nodes;

the exporting step comprises exporting tags for a particular book to a respective tag repository located on a predetermined node; and

the selecting step comprises selecting relevant tags from among all of the tag repositories.

15. The method of claim 4, wherein:

the tag repository is distributed across a plurality of networked nodes running a filesystem;

the exporting step comprises creating a common, shared directory including the tags for all of the books; and

the selecting step comprises selecting relevant tags from the common directly using utilities provided by the filesystem.

16. The method of claim 4, further comprising the step of:

updating a respective tag database for the book every time the book is updated;

wherein the updating step comprises writing new entries to the tag database for each new tagged iunit and updating existing entries in the tag database as required;

wherein the exporting step comprises exporting information about new and updated entries in the tag database to the tag repository.

17. The method of claim 16, wherein the selecting step comprises:

accessing, upon request of an author of the second book, all tag repositories associated with the document set; and

selecting tags from the accessed tag repositories corresponding to the iunits to be imported from the first book.

18. The method of claim 17, further comprising the step of importing the iunit into the second book.

19. The method of claim 18, wherein the step of importing the iunit is selected from importing the iunit by reference or importing the iunit by inclusion.

20. A computer based band system for linking data in a document set including a plurality of books, comprising:

a tag that provides information about an information unit (iunit) from a first book, including a semantic attribute and a unique identifier;

a tagexporter configured to export the tag to a tag repository; and

a tagfinder configured to select the tag from the tag repository and import the iunit to a second book.

21. The system of claim 20, wherein the tagexporter is controlled only by an author of the first book.

22. The system of claim 21, wherein the semantic information comprises a meaningful description provided by an author of the first book, the semantic information being viewable and searchable in the tag repository to enable an iunit of a desired semantic type to be selected for importation in the selecting step.

23. The system of claim 22, wherein each book has a respective set of authors and comprises a self-contained unit of document administration.

24. The system of claim 23, wherein each book comprises at least one document, each including one or more document units.

25. The system of claim 24, wherein each document unit corresponds to a respective computer file.

26. The system of claim 25, wherein the identifier uniquely identifies the document unit, document and book with which the iunit is associated.

27. The system of claim 26, wherein the tag is stored in a doctag file with an associated doctag URL;

such that the tagfinder is configured to access the identifier for importation of the iunit into the second book via the doctag URL.

28. The system of claim 27, wherein the doctag file is stored on a network node that hosts the first book.

29. The system of claim 28, wherein the network node comprises:

a set of document URLs;
