Agenda

 

1.	Scribe
2.	Accessibility Summary is now a recommendation (should) not a
requirement (must) in the EPUB Accessibility Conformance and Discoverability
Specification 1.1 in CR. The change happened last week.
3.	Background

3.1 official definition of accessibilitySummary in schema.org

https://schema.org/accessibilitySummary

"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."

 

3.2 There has been a change to the conformance section 3.5.2 of the EPUB
Accessibility Conformance and Discoverability specification 1.1. Now the
metadata is clearly understandable as a natural language description of
conformance. The strings are required and can be parsed to align with
specific statements.

 

https://www.w3.org/TR/epub-a11y-11/

Here is the text: 

 

To indicate conformance to the accessibility requirements of this
specification, an EPUB publication [epub-3] MUST specify in its metadata
section a conformsTo property [dcterms] exactly matching (i.e., both in case
and spacing) the following pattern:

EPUB-A11Y-A11Y-VER_WCAG-WCAG-VER-WCAG-LVL

where:

A11Y-VER

Specifies the version number of the EPUB Accessibility specification the
publication conforms to. The value MUST NOT include decimal points (e.g.,
the value 11 indicates this version of this specification).

WCAG-VER

Specifies the version number of WCAG the publication conforms to. The value
MUST NOT include decimal points (e.g., 20 for WCAG 2.0 or 21 for WCAG 2.1).

WCAG-LVL

Specifies the WCAG conformance level the publication conforms to (e.g., A or
AA).

EXAMPLE 1: A basic conformance statement

In this example, the EPUB creator is stating that their publication conforms
to the EPUB Accessibility 1.1 specification at WCAG 2.1 Level AA.

<package .>

   <metadata .>

     .

      <meta 

          property="dcterms:conformsTo"

          id="conf">

         EPUB-A11Y-11_WCAG-21-AA

      </meta>

      .

   </metadata>

  .

</package>

The following conformance strings are valid as of publication of this
specification:

. EPUB-A11Y-11_WCAG-20-A

. EPUB-A11Y-11_WCAG-20-AA

. EPUB-A11Y-11_WCAG-20-AAA

. EPUB-A11Y-11_WCAG-21-A

. EPUB-A11Y-11_WCAG-21-AA

. EPUB-A11Y-11_WCAG-21-AAA

NOTE

The list of valid conformance strings will increase as W3C releases new
versions of WCAG.

In addition, WCAG 3.0 is set to introduce new level names (currently Bronze,
Silver and Gold). Those names will likely replace A, AA, and AAA in the
string pattern, but conformance will be addressed after that specification
becomes a W3C Recommendation.

Introduction

Note: Reference to the User Experience guide.

Principles 1: - I was thinking this would be a restatement/pointer to the
Schema.org definition of the accessibility Summary

Principles 2: I thought this would be a description of the presentation of
the accessibility metadata presented through the User Experience Guide,
i.e., this is all the accessibility metadata that is normally identified.

Principle 3: This would reference the conformance metadata statements
referenced above, e.g.       <meta 

          property="dcterms:conformsTo"

          id="conf">

         EPUB-A11Y-11_WCAG-21-AA

      </meta>
