EPUB Overview form 30000 FeetA freely-available e-book format based on the

modern web technology such as HTML5 and CSS3.Designed by International Digital Publishing ForumA 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 EPUB3HTML5 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

predeterminedTypeset (paginated) prior to distributionBy 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 textHave 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 EPUB3Major rendering engines such as WebKit by

Apple/Google and RMSDK by Adobe (and more in the future).

JBasic provides the following.A markup guideline documentXHTML files as templatesCSS stylesheets (to be announced)Sample EPUB publications (to be announced)

Issues in JBasicSemantic tags of HTML5 ? (Yes, in a few

weeks)Good for accessibilityAlmost no experiences yet.

The epub:type attribute? (Yes, in a few weeks)Good for accessibilitySince CSS Namespace is not widely supported

yet, we need the class attribute as well.Is the EPUB 3 Structural Semantics Vocabulary

good enough?

Standardization of EPUB at ISO or IEC

ISO/IEC JTC1/SC34/AHG4 (EPUB) Co-Convener

MURATA Makoto (together with Dr. Yong-Song Cho)

ISO / IEC JTC1 meeting (2010-11-16) Resolution 58: EPUB standardsJTC 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 ForumIEC / 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
