Examples
Example 1 — EPUB 3
<meta property="schema:accessibilityFeature">

</meta>
Example 2 — EPUB 2
<meta name="schema:accessibilityFeature"
content="ChemML"/>
Example 3 — Audiobooks
"accessibilityFeature": ["ChemML"]
Explanation
The ChemML
value is used to indicate that a publication contains chemical information (e.g., molecules
and reactions) encoded using the ChemML markup language.
This value is not typically used with publications at this time as there is no support for rendering ChemML in HTML.
Example of ChemML markup.
<cml xmlns="http://www.xml-cml.org/schema" title="Chem sample" …>
<molecule id="mol" …>
…
</molecule>
</cml>
ONIX Mapping
The ChemML
value maps to list 196
code 18 ("Accessible chemistry content
(as ChemML)").
A publication with chemical content will typically also set list 81 code 47 ("Chemical content"). This value is equivalent to setting a textual access mode.
