ChemML

Category: - -

Definition

Identifies that chemical information is encoded using the ChemML markup language.

Examples

Example 1 — EPUB 3

<meta property="schema:accessibilityFeature">
   ChemML
</meta>

Example 2 — EPUB 2

<meta name="schema:accessibilityFeature"
      content="ChemML"/>

Example 3 — Audiobooks

"accessibilityFeature": ["ChemML"]

Explanation

The ChemML value indicates 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.
