Baseline for Born Accessible EPUB 3

  1. 1. Baseline for Born Accessible EPUB Implementing the Legislative Strategy: Accessible Digital Publishing within & beyond the legal threshold George Kerscher 9th European e-Accessibility Forum June 8th 2015
  2. 2. Inclusive Publishing Industry •trade and educational publishers •journal and magazine publishers •comics and Manga industry •disability-focused organizations •educational institutions •governmental organizations •tech companies •standards organizations
  3. 3. Publishers ask: “What do I need to do to make my publications accessible to persons with disabilities?” Agreement needs to be reached on the baseline features. •It is not easy •We must push the bar higher •We must be practical
  4. 4. •Publication must provide accessible content in EPUB 3 (or future version) •Reading system used must support EPUB 3 content •Publication, in the context of the reading system, must be useable with Assistive Technology (AT) Consensus: All 3 components must be working or it is impractical to include a given feature as a requirement for accessibility in published documents. EPUB 3 Designed for Everybody Requirements
  5. 5. Today Publishers can deliver the text of their publication in a well- structured, logical reading order, even if images are used for title or headings as long as ALT text is there. •EPUB reading systems can present the full text of an EPUB 3 publication on every platform. •Assistive Technology (AT) can integrate with reading systems and speak the text using synthetic speech (TTS), as refreshable braille using a Bluetooth device, or enlarge the text on the screen. Consensus: Well-structured text in a logical reading order is a baseline requirement for a Born Accessible publication.
  6. 6. HTML 5 Content Structure To benefit all readers, publishers must make use of the native semantics of HTML 5 – starting point of accessible content, foundation for digital publishing This will enable: •logical reading order •effective navigation •skipping and escaping content Consensus: Native HTML 5 elements will be used to correctly identify content structure
  7. 7. Images, ALT text & Additional Enhancements •Images used for ornamental purposes •Images & graphics can be made accessible using ALT text •Images, charts, diagrams, maps, infographics…..convey information that may need to be customized for different types of learners Consensus: Publishers will identify ornamental images. ALT text (W3C A & AA guidelines) / Accessible EPUB 3: Best Practices by Matt Garrish & DIAGRAM’s Image Guidelines for EPUB 3. Coming: BISG Quick Start Guide for Accessibility.
  8. 8. Metadata, Asserting Conformance Metadata will be necessary for discovery, marketing, sales and inclusion in educational coursework. Consensus: Metadata will identify the accessibility features of publications that confirm to the baseline Born Accessible agreed-upon features, as defined in the ONIX code (List 196) and which includes a set of accessibility metadata
  9. 9. Enhancements to Born Accessible Publications •Adding value by using Diagrammar: A Framework for Making Images and Graphics Accessible •Republishing materials for persons who are not technologically capable – the safety net •Future enhancements delivered separately as annotations •Reading system would integrate those annotations with the commercially available Born Accessible version •DAISY Consortium members make terrific partners to make information fully accessible
  10. 10. Educational Publications and the EDUPUB Profile of EPUB 3 •Modern educational publications in EPUB 3 format are anticipated to use the EDUPUB profile •Videos need to be captioned •Support for MathML rapidly evolving •Scripted components, widgets, assessments, 3D (WebGL) demonstrations, data visualizations, SVG Consensus: Educational materials will have additional requirements in the baseline for Born Accessible EPUB 3 in the EDUPUB profile
  11. 11. Broadly Available EPUB 3 Authoring Tools •Needed in education for course content development •Needed in governmental organizations for publications •Needed for everyday use by authors, students and professionals
  12. 12. Conformance and Certification •Epubcheck, use it now •Pre-flight needed to assist with checking conformance •Self-certification linked to metadata •External certification of publisher content Consensus: Tools for evaluation, certification approaches, approved guidelines training and support will be topics for discussion
  13. 13. Reading System Testing - IDPF, BISG, DAISY Collaboration Fundamental accessibility tests available now.
  14. 14. Raising the Bar Consensus: The practical baseline features for Born Accessible publications are expected to advance as technology and work processes improve
  15. 15. Call to Action •Everybody is invited to participate in the evolving Inclusive Publishing Ecosystem •Formal announcement will kick off the collaborative effort •We do not expect to meet in-person, all virtual •DAISY Consortium will help to drive •Key principles: Consensus and practicality •We need to raise the bar over time Contact George Kerscher directly:
