Born Accessible EPUB
That Meets the Baseline
for Accessibility
George Kerscher

Standards at the Core of
Accessibility
● World Wide Web Consortium (W3C)
– HTML 5, CSS, SVG
● Web Accessibility Initiative (WAI)
● WCAG 2.0
● International Digital Publishing Forum (IDPF)
– http://www.idpf.org/
– EPUB the digital publishing standard
– EPUB Accessibility Conformance and Discovery
1.0 Specification
Page 4
● For the last three years the W3C has run a Digital
Publishing Interest Group
● The merger has placed EPUB under the domain
of W3C
● IDPF members will be given reduced fees for two
years
● 82% of members supported the combination
IDPF and W3C Merger
Page 5
● Adoption of EPUB 3 has been outstanding in most digital
publishing sectors
● EPUB 3.1 is an approved recommendation
– http://www.idpf.org/epub/31/spec/epub-spec.html
● Included is EPUB Accessibility 1.0
– http://www.idpf.org/epub/a11y/accessibility.html
● Conformance and Discovery Requirements for EPUB
Publications
● First ever spec to enable accessibility certification
– This establishes the baseline
● Important: We want to be practical in that publishers should
readily be able to produce accessible EPUB from their normal
production process
EPUB within the World Wide Web
Consortium (W3C)
Page 6
● Requires accessibility conformance in the EPUB
publication
● Builds on WCAG 2.0 with some additional publishing-
specific items
● in the USA WCAG 2.0 “AA” is generally recommended
● “conforms To” metadata pointing to “A,” “AA,” or “AAA”
Accessibility metadata must be included
● Interestingly: publishers have actively participated in the
EPUB Accessibility Spec development and have been
updating their production process to support accessibility.
Baseline Features
Page 7
● The Digital Publishing Interest Group in the W3C has
produced an ARIA 1.1 module to help add some Digital
Publishing semantics to ARIA
● Digital Publishing WAI-ARIA Module 1.0
– https://www.w3.org/TR/dpub-aria-1.0/
● This is currently under review and has not yet been
adopted as a recommendation
● Sample of the proposed new Roles:
– doc-abstract
– doc-appendix
– doc-chapter
– doc-introduction
W3C DPUB’s ARIA 1.1 Module
Page 8
● All headings must be marked in the HTML as headings
(Critical for navigation)
● All textual content must use HTML text markup, e.g.,
paragraphs, block quotes, list items
● All content must be in a logical reading order
● Images are marked as decorative, described in
surrounding text or captions, or have “alt” text
● If you want a fancy heading and use an image, remember
to surround the image with the heading markup and use
alt text (remember you can do very cool things these days
with CSS)
Concrete Examples of Some MUSTS
Page 9
Metadata Requirements to Be Compliant
● EPUBs wishing to be conformant MUST:
– include accessibility discovery metadata
– include the following [schema.org] accessibility
metadata
• accessMode
• accessibilityFeature
• accessibilityHazard
• accessibilitySummary
Page 10
● Specifications are at a high level and techniques are
concrete
● WCAG and EPUB techniques are maintained
independently of specifications
● As support in Reading Systems evolve, the techniques will
improve
● http://www.idpf.org/epub/a11y/techniques/techniques.html
● https://www.w3.org/TR/WCAG20-TECHS/Overview.html
● TTS & Braille: The techniques ensures that Text-to-
Speech can be used to present the information. Also, this
supports text being sent to a refreshable braille display
Supporting Techniques Updated
Frequently
Page 11
● Certify that digital books (and all other publications) meet
the Baseline
● Self-certification
– Sad Story: What happened to Voluntary Product Accessibility
Template (VPAT)?
– Would you have a fox guard the henhouse?
– DAISY is building the EPUB Accessibility Conformance Checker
– Auto checking must be supplemented by human inspection
Accelerating Publisher Adoption:
Certification of EPUB Publications
Page 12
● Excellent accessibility metadata required to be
present in the EPUB package
● Accessibility metadata supports
• Born accessible
• Find accessible
• Buy Accessible
● Questions: Any questions on the Standards side?
Accelerating Publisher Adoption:

Benetech Certification
Pilot

Page 14
Born Accessible: Certified by Benetech
● Benetech is piloting the certification process
● A documented process for certification must
be established and followed
● Publisher materials are reviewed and
remediated
● Long term process improvements would be
recommended to publishers
Page 15
Certification Metadata in EPUB
Publications
● How to find certified content in the future:
– certifiedBy: Specifies the name of the party that
certified the content. The certifier of the content could
be the same party that created the EPUB publication,
but can also be a third-party accessibility certifier.
– certifierCredential: Identifies a credential or badge
that establishes the authority of the party identified in
the certifiedBy property to certify content is accessible.
– certifierReport: Provides a link to an accessibility
report created by the party identified in the certifiedBy
property.
– conformsTo: WCAG-A, -AA, or -AAA
Page 16
Tested Software for Reading EPUB
● Both the EPUB and the Reading System must be
accessible.
● A perfectly accessible EPUB with a terrible Reading
System does not get you there
● Likewise a great Reading System with an inaccessible
EPUB yields zero
● The answer is to test Reading Systems with perfect
EPUBs
● It is necessary to test using a wide range of Assistive
Technologies
● http://www.epubtest.org/
– Note: VitalSource Bookshelf at 100%

Buy Accessible
● Procurement MUST focus on “Buy Accessible”
● “Buy Accessible” - Demand Certified Accessible
EPUB 3
● All content must be certified. Point them to
“Certified by Benetech” initiative.

Publishers Perspective
● Rachel Comerford
Page 24
Process is Everything
Publisher’s processes are at the heart of the Certification
Page 25
How we Integrated New Standards
● Get involved in working groups – it’s a chance to share
your solutions and learn from others
● Standards groups provided specifications but it was up to
us to develop implementation guides based on our needs
– V1 took 6 months to build
– updates are coming out every 2-3 months based on feedback
● Developed a validator based on open source resources
and our implementation guide
– Update with every implementation guide update
● Established a checklist for non-automated QA and
educated team members on what to look for
Page 26
Sharing Responsibility
● Art – Develop all art to have proper contrast, readable text
● Design – Ensure read order is clearly indicated
● Authors – Provide guidance about pedagogical intention
for digital conversion
● Editors – Communicate with authors about focus and
development
● Compositor – Apply publisher standards, give feedback on
gaps
● Quality Assurance – Automated and manual checking of
everything developed
Page 27
Addressing Complexity
● Text with markup
● Complex image layouts
● Marginal elements
– Texts contain a large quantity of pedagogical material in the margin
● MathML
– Reader compatibility is not standard
– Expensive and difficult to write alt text
● ChemML
– Reader compatibility is rare
– Expensive and difficult to write alt text
● Graphic Novel
– All image text
Page 28
Why Are We Doing This?
● ‘Certified by Benetech’ advantages
– 3rd party confirmation of accessibility standards
– Assurance for students and adopters
– Easy to roll up to administrators
– Gives us feedback to pass on to vendors about the quality of their
work
– Provides internal confidence about the quality of what we’re
delivering
– Helps identify for schools what errors are addressed and what
warnings are relevant
– Most importantly: Shows us what we’re missing and what we
have left to learn

Editor's Notes

  • #23 This Table shows a snapshot of the accessibility scores for thirty titles evaluated as of February 10, 2017. Most of the EPUBs tested failed certification (requiring to meet WCAG-A compliance) with an average score of 64% and an average complexity level of 2.9 out of 5. Trends showed that Links, and Lists were correctly structured -- above 85% -- with Images, Tables, General Accessibility structured poorly (below 60%).   The table is brightly colored with bolded green text cells having a passing grade for the various titles, and any feature scoring below 70% appearing non-bolded in red.   The publishers and titles of the EPUBs were omitted due to confidentiality restrictions. This clearly shows that two of the six participants (one of which represented multiple publishers) had mostly accessible EPUBs but that all had some issue, especially with image descriptions and accessible table support.
