Definition

Identifies that mathematical equations and formulas are encoded in the LaTeX typesetting system.

Examples

Example 1 — EPUB 3
<meta property="schema:accessibilityFeature">
   latex
</meta>
Example 2 — EPUB 2
<meta name="schema:accessibilityFeature"
      content="latex"/>
Example 3 — Audiobooks
"accessibilityFeature": ["latex"]

Explanation

The latex value is used to indicate that a publication contains math equations formatted using the LaTeX typesetting system.

LaTeX equations can retain semantic information about math equations that is not always available in other formats (e.g., presentational MathML) making them easier to understand.

The ability to read LaTeX equations often requires being able to export the data to another program, however, as LaTeX does not natively render in Web-based formats like EPUB. As a result, it is not commonly found at this time.

A latex-formatted equation.

\begin{equation} f(x)=(x+a)(x+b) \end{equation}

ONIX Mapping

The latex value maps to list 196 code 35 ("Accessible math content (as LaTeX)").

A publication with mathematical content will also set list 81 code 48 ("Mathematical content"). This value is equivalent to setting a textual access mode.
