Examples
<meta property="schema:accessibilityFeature">
latex
</meta>
<meta name="schema:accessibilityFeature"
content="latex"/>
"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.
