A structurally an semantically correct XML source document can be use to create many different output formats, such as:

• A DAISY 2.02 Talking Book
• A DAISY 3 Talking Book
• Braille Print
• Dynamic Braille
• Large-print
• E-text (ascii, xhtml, ...)

One XML master - reusability

• for different output formats
• for new editions of the same book

Daisy 3 - DTBOOK DTD

This DTD is purposively designed for the single source master concept.

Using XSLT and other automated or semi-automated transform processes, the source document can be prepared for the output destination, if needed at all (dtbook is in itself a good e-text format for example).

Strict XHTML 1.0 documents can also be upgraded to DTBOOK at a later stage using XSLT.

Challenges

Legislation

Access to publishers files

Output format variations

Methodologies

• Manual typing
• Scanning with automated conversion into text (ascii, rtf)
• Publisher files conversion
