NIMAS Exemplars


This page is intended to serve as a resource for those interested in learning more about what a NIMAS-conformant delivery should include. Exemplars include the following baseline items:

  1. NIMAS 1.1-conformant XML file(s)
  2. Package file
  3. PDF of title page or whichever page contains copyright and ISBN information
  4. Images in SVG, PNG, or JPG format at 300 dpi

The document type declaration belongs at the top of each XML file as shown:

National Instructional Materials Accessibility Standard (NIMAS)

A technical standard used to produce XML-based source files for print-based educational materials.

XML (EXtensible Markup Language)

Universal format for structured documents and data. Set of rules, guidelines, and conventions for designing text formats for data.

Preparers of NIMAS-conformant files are strongly encouraged to use full DAISY mark-up whenever possible.

Note: Detailed information on mark-up and image file organization may be found in Creating NIMAS Files, a NIMAS Resource page document.

Interested parties may contribute exemplar content to this page. To begin the submission process, send a note to indicating interest in providing content examples. Exemplar submissions must include NIMAS 1.1-conformant XML content file(s), a package file, and a PDF file of the source content's title page or whichever page contains copyright and ISBN information. Exemplar XML files must validate to the NIMAS 1.1 DTD in order to be considered for posting to this site. For details about how to handle images in a NIMAS 1.1-conformant file set, see the appropriate section of Creating NIMAS Files.

Assurances must also be provided with regard to the ownership and/or rights to all content (i.e., text and images). Any conditions for use of the files by others should be provided with the files. The files themselves may also include such information.

The AEM Center reserves the right to post or reject all submissions. Exemplar submissions will be posted in the order in which they are submitted, with current files listed at the bottom. Each submission should include an assurance that rights for posting the content is provided to the NIMAS Technical Assistance Center.

Exemplar Downloads

Each exemplar submission links to a page with downloadable files and additional information.

Please note: NIMAS 1.1 package files validate to the OEBPS standard 1.2 specification. They are NIMAS 1.1 OPF files, not DAISY OPF files.

NIMAS filesets must also meet metadata submission requirements for the National Intstructional Materials Access Center ( NIMAC), the national repository of NIMAS filesets. NIMAS exemplar filesets include OPF files that are valid to the NIMAS specification and to NIMAC submission requirements. A NIMAC-specific OPF sample is available below.

Current Baseline NIMAS files conform to the NIMAS 1.1 specification, which became official through the U. S. Department of Education on July 19, 2006.
