Download the DAISY and NIMAS in HTML guide

The National Instructional Materials Accessibility Standard (NIMAS) is a technical standard used to produce source files in XML format that may be used to develop multiple specialized outputs in a variety of formats for students with print disabilities. The XML and image source files of a NIMAS fileset can be used to create Braille, large print, HTML, DAISY digital talking books (DTBs) using human voice audio or text-to-speech synthetic audio, and more. (The NIMAS applies to instructional materials published [available for purchase or in print] on or after 7/19/06.)

The NIMAS is a sub-set of the DAISY Standard. DAISY stands for Digital Accessible Information SYstem and refers to an international standard for creating a variety of DTBs: digital books that are a combination of synchronized text and audio. The DAISY specification is made up of internationally agreed-upon rules and requirements necessary to create digital and audio books, including XML and SMIL file requirements and structural and other aspects.  This guide is based on the DAISY 2005-3 and NIMAS 1.1 technical specifications. 

Both DAISY and the NIMAS use XML and therefore XML's most important asset: the separation of content from its presentation. By using content's structure and components as a source, and creating from it a variety of outputs or products with very different format, layout, presentation, and features; the results may then be used to support a diverse group of learners and users with print disabilities.

This guide is intended to assist publishers and other producers of accessible educational materials (AEM) to create accessible HTML outputs sourced from NIMAS filesets. Several of the elements of the DAISY Standard and the NIMAS technical specification do not have HTML equivalents. This guide was prepared to address the question of how DAISY/NIMAS elements without direct corresponding elements can be converted into HTML and to cover important aspects of a NIMAS to HTML conversion project.

Accessible Educational Materials (AEM)

Print- and technology-based educational materials designed to be usable across the widest range of individual variability.
