Creating NIMAS Files
This guide is intended to help publishers and conversion houses to respond to state and local education agency requirements to prepare NIMAS filesets when textbooks are adopted or purchased and contains practical information regarding the creation of a NIMAS fileset.
A NIMAS fileset consists of the following:
- XML content file,
- a package file (OPF),
- a PDF-format copy of title page and ISBN and copyright information pages, and
- a full set of content images in SVG, JPG, or PNG format.
A NIMAS fileset is a set of source files that may be rendered into a variety of output formats, including student-ready versions such as audio books, Braille editions, etc. It is not a post-production product; it is a pre-production product. NIMAS files are intended for use by publishers, authorized entities, and others to produce accessible versions of printed instructional materials. They are not intended to be used as-is and should not be considered finished products. XML content files in NIMAS filesets must be conformant to the NIMAS 1.1 specification, a sub-set of the DAISY 2005-2 DTD. By definition, a NIMAS XML file will validate to the NIMAS 1.1 DTD.

DAISY Structure Guidelines
Last revised June 4, 2008
The DAISY Structure Guidelines were written to assist producers of talking books. They focus on how the textual content file of a DAISY Digital Talking Book (DTB) is to be marked up or "tagged" to clearly define the structure of the book.
Establishing standards for applying structure is a necessity in the international exchange of information. A single standard facilitates the exchange of digital talking books (DTBs) regardless of where they are produced. Global consensus on the organization and structure of DTBs may impact future developments in recording and playback software and devices. Ultimately readers who are blind, visually impaired or print disabled benefit.
The Creating NIMAS Files document provides information on the correct application of the XML element set DTBook, a key segment of the DAISY/NISO standard. Formally, this ANSI/NISO Z39.86 standard is referred to as the Specifications for the Digital Talking Book. Links to the standard and information on its development and use can be found on the DAISY Consortium website.
When a DAISY/NISO DTB includes a textual content file, DTBook elements will be used to mark up that file. The resulting file must be valid to the XML Document Type Definition, the DTBook DTD, as specified in the DAISY/NISO Specification. The file may be synchronized with the corresponding audio file to allow synchronized presentation of content in multiple formats (audio, braille, enlarged type, etc.).
