Abstract

A technique, system, and computer program by which content created from source files in a first data format and converted to presentation files in a second data format can be read and used by a subsystem which reads content in a third data format other than the first and second data formats. Identifying information from the source files and/or presentation files is extracted and stored in a map file in the third format. If desired, a Table of Contents (TOC) file in the third data format can also be created by using the map file and a TOC file in the second data format. The first data format can be Standardized General Markup Language (SGML), the second data format can be HyperText Markup Language (HTML) and the third data format can be Extensible Markup Language (XML).

Claims

1. In a computing environment having a system which makes content available for use by a subsystem, said content being converted from source files in a first data format to presentation files in a second data format, said subsystem reading said content in a third data format other than said first or second data formats, a computerized method of indexing said content so that it can be correctly accessed and displayed by said subsystem, comprising the steps of:

extracting identifying information from said source file;

creating a map file in said third data format containing said extracted identifying information;

configuring said subsystem to access and display said presentation files in said second data format based on said map file; and

creating a first Table Of Contents (TOC) file in said second data format; and

generating a second TOC file in said third format based on said first TOC file and said map file.

2. A method as set forth in claim 1, wherein said third data format is Extensible Markup Language (XML).

3. A method as set forth in claim 1, wherein said second data format is HyperText Markup Language (HTML).

4. A method as set forth in claim 1, wherein said first data format is Standardized General Markup Language (SGML).

5. A method as set forth in claim 1, wherein said first data format is Standardized General Markup Language (SGML), said second data format is HyperText Markup Language (HTML), and said third data format is Extensible Markup Language (XML).

6. A method as set forth in claim 1, wherein said creating step includes the removal of extraneous coding of said second format from said map file.

7. A method as set forth in claim 1, wherein said step of generating said second TOC file includes the steps of:

reading each entry in said first TOC file;

matching each entry in said first TOC file with a corresponding entry in said map file; and

extracting data corresponding to each matched entry and storing said extracted data in said second TOC file.

8. In a computing environment having a system which makes content available for use by a subsystem, said content being converted from source files in a first data format to presentation files in a second data format, said subsystem reading said content in a third data format other than said first or second data formats, computer readable medium containing computer readable code readable by a computer in said environment, for indexing said content so that it can be correctly accessed and displayed by said subsystem, comprising:

a subprocess for extracting identifying information from said source file;

a subprocess for creating a map file in said third data format containing said extracted identifying information;

a subprocess for configuring said subsystem to access and display said presentation files in said second data format based on said map file; and

a subprocess for creating a first Table Of Contents (TOC) file in said second data format; and

a subprocess for generating a second TOC file in said third format based on said first TOC file and said map file.

9. Computer readable medium as set forth in claim 8, wherein said third data format is Extensible Markup Language (XML).

10. Computer readable medium as set forth in claim 8, wherein said second data format is HyperText Markup Language (HTML).

11. Computer readable medium as set forth in claim 8, wherein said first data format is Standardized General Markup Language (SGML).

12. Computer readable medium as set forth in claim 8, wherein said first data format is Standardized General Markup Language (SGML), said second data format is HyperText Markup Language (HTML), and said third data format is Extensible Markup Language (XML).

13. Computer readable medium as set forth in claim 8, wherein said creating subprocess includes a step for removing of extraneous coding of said second format from said map file.

14. Computer readable medium as set forth in claim 8, wherein said subprocess of generating said second TOC file includes the steps of:

reading each entry in said first TOC file;

matching each entry in said first TOC file with a corresponding entry in said map file; and

extracting data corresponding to each matched entry and storing said extracted data in said second TOC file.

15. A system for making content available in a computing environment for use by a subsystem, said content being converted from source files in a first data format to presentation files in a second data format, said subsystem reading said content in a third data format other than said first or second data formats, said content being indexed so that it can be correctly accessed and displayed by said subsystem, comprising:

means for extracting identifying information from said source file;

means for creating a map file in said third data format containing said extracted identifying information;

means for configuring said subsystem to access and display said presentation files in said second data format based on said map file; and

means for creating a first Table Of Contents (TOC) file in said second data format; and

means for generating a second TOC file in said third format based on said first TOC file and said map file.

16. The system as set forth in claim 15, wherein said third data format is Extensible Markup Language (XML).

17. The system as set forth in claim 15, wherein said second data format is HyperText Markup Language (HTML).

18. The system as set forth in claim 15, wherein said first data format is Standardized General Markup Language (SGML).

19. The system as set forth in claim 15 wherein said first data format is Standardized General Markup Language (SGML), said second data format is HyperText Markup Language (HTML), and said third data format is Extensible Markup Language (XML).

20. The system as set forth in claim 15, wherein said creating subprocess includes a step for removing of extraneous coding of said second format from said map file.

21. The system as set forth in claim 15, wherein said subprocess of generating said second TOC file includes the steps of:

reading each entry in said first TOC file;

matching each entry in said first TOC file with a corresponding entry in said map file; and

extracting data corresponding to each matched entry and storing said extracted data in said second TOC file.
