Definition

A human-readable summary of specific accessibility features or deficiencies, consistent with the other accessibility metadata but expressing subtleties such as "short descriptions are present but long descriptions will be needed for non-visual users" or "short descriptions are present and no long descriptions are needed."

Examples

Example 1 — EPUB 3
<meta property="schema:accessibilitySummary">
   This publication conforms to the EPUB Accessibility specification 
   at WCAG Level AA.
</meta>
Example 2 — EPUB 2
<meta name="schema:accessibilitySummary"
      content="This publication conforms to the EPUB Accessibility specification at WCAG Level AA."/>
Example 3 — Audiobooks
"accessibilitySummary": "This publication conforms to the EPUB Accessibility specification at WCAG Level A."
Example 4 — HTML with RDFa
<p property="accessibilitySummary">
   This document conforms to WCAG 2.0 Level AA.
</p>
Example 5 — HTML with microdata
<p itemprop="accessibilitySummary">
   This document conforms to WCAG 2.0 Level AA.
</p>
Example 5 — Summary in multiple languages (EPUB 3)

In this example, the xml:lang attribute is used to identify the language of the summary.

<meta property="schema:accessibilitySummary" xml:lang="en">
   <!-- English language summary --> 
</meta>

<meta property="schema:accessibilitySummary" xml:lang="fr">
   <!-- French language summary --> 
</meta>

Value

The summary is a brief, human-readable summary of features and/or deficiencies. It is used to indicate conformance to an accessibility standard or point out shortcomings to the standard.

The summary should not be a simple repetition of all the accessibility features and hazards.

Do not repeat this property unless it contains the summary in another language. In the case of multiple summaries, use the xml:lang and/or lang attributes to differentiate the language.
