NIMAS: Excessive Images in Mid-level Mathematics BooksNIMAS: Excessive Images in Mid-level Mathematics BooksDAISY 3 Structure Guidelines
Last Revised: June 4, 2008
This page is initially intended for discussion. This section will be expanded as resolution is reached. The information provided here is specific to books produced to the NIMAS Standard; it does not apply to books produced to the DAISY Standard.
The DAISY MathML Modular Extension Mathematics was approved February 23, 2007. Producers creating DAISY/NISO, that is, DAISY 3 books which contain mathematical notations should incorporate the DAISY MathML Extension into their production processes.
See the DAISY Specification for MathML. See also the section in the Part II(g): Mathematics in these Guidelines.
The current NIMAS recommendation is for all mathematical content to be inserted into the document as an image. While this may be appropriate for titles with an average number of mathematical objects, many mid-level mathematics textbooks are filled with mathematical objects, with an average of 25+ equations per page. An example, and the marked-up text as required by the NIMAS Standard are given below.

<p><strong>Remember</strong> that if the whole number factor is
divisible by the denominator of the fraction factor, you can
divide first and then multiply.</p>

denominator.</p>
