Transition to Inclusive EPUB 3 eco System

Avneesh SinghCo-chair, TIES project

Objective

Facilitate the DAISY production houses to migrate to inclusive publishing system using the EPUB 3 specifications.

3 Dimensional approach

• Production processes and systems (Migration to accessible EPUB 3

• Publisher relationships (relationship between DAISY production centres & publishers)

• Consumption of accessible content (Reading systems)

Navigable Audio-Only EPUB 3 Guidelines

• Navigable audio-only books form 90% of DAISY collection

• Working draft of Navigable Audio-only EPUB 3 Guidelines:http://www.daisy.org/ties/navigable-audio-only-epub3-guidelines

• Navigation on basis of Sections, pages & skippable structures

Braille production from EPUB 3

• EPUB 3 is text centric, great source for producing Braille

• Potential to automate 90% to 95% of Braille production

• But the remaining 5% to 10 % requires special treatment

• Most of times this 5% to 10% is the most important component of the publication

• Need capability to associate the specially treated Braille (embosser ready Braille) with the publication.

Braille production from EPUB 3 contd.

Approaches identified are:

• W3C Open Annotations

• John Boyer’s UTML mark-up

• DIAGRAM content model.

DIAGRAM Content Model

• Tactile element can point to external Braille files like BRF, ASCII arts, Unicode Braille, SVG etc.

• DIAGRAM xml containing the tactile element can be referred by the the EPUB 3 publication by using describedby or describedat attributes

Survey hosted by TIES Production Group

• 37 DAISY producing organizations responded to the survey

• Most organizations produce Leisure reading, education books with simple mark-up & children books

• A few produce Education books with complex mark-up & Newspapers

• 17 has either introduced EPUB 3 or have started experimental EPUB 3 production.
