EPUB Overview form 30000 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

HTML5 in EPUB3
 HTML5 is a buzz word.
 HTML5 provides semantic tags such as <section>,
<article>, <nav>, <header>, <footer>, <figure>,
<figcaption>, etc.
 HTML5 allows interactive applications by its powerful
APIs.

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?

MURATA Makoto
(together with Dr. Yong-Song Cho)
ISO / IEC JTC1 meeting (2010-1116) 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.

SC 36 (Information Technology for Learning Education and
Training)

Documentation)

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
