The DAISY/NISO Standard defines a comprehensive system for Digital Talking Books. A part of this Standard is DTBook, an XML vocabulary that provides a core set of elements that are needed to produce most types of books. However, DTBook is not intended to be an exhaustive vocabulary for all types of books.
Many organizations have inquired about the correct approach to extend the DAISY/NISO Standard so that it can address additional needs. Some extensions that have been mentioned are for mathematics, video support, testing, workbooks, music, dictionaries, chemistry, searching and more.
