EPUB Overview form Feet A freely-available e-book format based on the modern web technology such as HTML5 and CSS3. Designed by International Digital Publishing Forum A lot of momentum all over the world (Apple, Sony, Google, Kobo, B&N, and so forth) except Seattle. But Amazon accepts EPUB from publishers, and US major publishers do submit EPUB publications. The latest version, namely EPUB3, was completed in October, 2011.

Basic principles of EPUB3 The synergy with the Web world and the E-book world The support of languages and cultures all over the world One accessible format (EPUB3) rather than two, namely non-accessible-but-widely-used EPUB2 and accessible DAISY 3

What is a Fixed-Layout Publication? Any document with a layout that is predetermined Typeset (paginated) prior to distribution By contrast, dynamic (reflowable, adaptive) publications have layouts that are determined dynamically by Reading Systems If fixed-layout documents can be adapted (reflowed), the results are typically lossy Comics/manga are a type of fixed-layout documents Contain significant % of artwork as well as text Have pages divided into regions (cells / frames)

JBasic: a Japanese guideline for EPUB3 by a private company “East” Targets Narrative and text-dominated e-books in the Japanese language Authors and editors overwhelmed by EPUB3 Major rendering engines such as WebKit by Apple/Google and RMSDK by Adobe (and more in the future). JBasic provides the following. A markup guideline document XHTML files as templates CSS stylesheets (to be announced) Sample EPUB publications (to be announced)

Issues in JBasic Semantic tags of HTML5 ? (Yes, in a few weeks) Good for accessibility Almost no experiences yet. The epub:type attribute? (Yes, in a few weeks) Good for accessibility Since CSS Namespace is not widely supported yet, we need the class attribute as well. Is the EPUB 3 Structural Semantics Vocabulary good enough?

ISO/IEC JTC1/SC34/AHG4 (EPUB) Co-Convener MURATA Makoto (together with Dr. Yong-Song Cho)

ISO / IEC JTC1 meeting ( ) Resolution 58: EPUB standards JTC 1 resolves that SC 34 initiate a joint activity inviting IDPF, IEC/TC100 TA10, SC 29, SC 36 and potentially ISO/TC 46/SC 4 (and others) to develop a strategy for the possible standardization of EPUB 3.0 and necessary complementary interfaces. International Digital Publishing Forum IEC / TC 100 TA10 (Multimedia e-publishing and e-book) SC 29 (Media Coding Information) SC 36 (Information Technology for Learning Education and Training) ISO / TC 46/SC 4 (Computer Use in the Information and Documentation) Others JEPA EPUB 日本語拡張仕様セミナー 24

Prospect Likely to be done by a joint working group under JTC1/SC34. Likely to become a Technical Specification first rather than an International Standard
