GENERIC FORMAT FOR E-PUBLISHING

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that
compliance with this document may involve the use of a patent.
The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he/she is willing to negotiate licences under reasonable

and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement
of the holder of this patent right is registered with the IEC. Information may be obtained from:

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights other than those identified above. The IEC shall not be held responsible for identifying any or all such
patent rights.

publishing and e-books, of IEC technical committee 100: Audio, video and multimedia
systems and equipment.

INTRODUCTION
Markets for multimedia e-book and e-publishing require standardization of formats for e-book

data interchange among associated people; authors, data preparers, publishers and readers.

The formats are classified into submission format, generic format and reader’s format. The

submission format has to support an interaction between authors and data preparers. The

reader’s format depends on e-publishing equipment. The generic format has to provide an

interchange format for data preparers and publishers and therefore should be e-publishing

equipment independent.

GENERIC FORMAT FOR E-PUBLISHING

1 Scope
This International Standard specifies a generic format for multimedia e-publishing employed

for e-book data interchange among data preparers and publishers, satisfying a number of
publishers requirements: revisable, extensible and heterogeneous logical structure.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 62229:2005, Multimedia systems and equipment – Multimedia e-publishing and e-books –
Conceptual model for multimedia e-publishing
ISO/IEC 19757-2:2003 Information technology – Document Schema Definition Language
(DSDL) – Part 2: Regular-grammar based validation – RELAX NG
Amendment 1 (2003)
ISO 639, Codes for the representation of names of languages
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
multimedia e-book
multimedia content consisting of texts, graphics, sounds and/or videos
3.2
data preparer
organization or person that prepares an e-book. An editor is an example of a preparer

3.3
publisher
organization or person that issues and distributes an e-book
3.4
generic format
format for multimedia e-book contents created and edited by a data preparer and modified by
a publisher to a reader's format for e-book distribution
4 Position and requirements for generic format
4.1 Generic format in contents creation/distribution model
The conceptual model for multimedia e-publishing (IEC 62229) defines a contents creation/
distribution model shown in Figure 1.

62448 © IEC:2007(E) – 7 –
Author <--(1)--> Data preparer <--(2)--> Publisher --(3)--> Reader

IEC  2379/06
Figure 1 – Contents creation/distribution model

Between the adjacent processing steps, data preparer and publisher, e-book contents data

are interchanged using the generic format. Merging original texts, graphics, sounds and/or

videos provided by authors, the data preparer creates and edits the e-book data in a generic

format. The e-book data are stored and forwarded to the publishers.

Publishers modify the generic format into reader’s formats appropriate for distribution
schemes and devices. The generic format can be used for e-book distribution as well.
4.2 Requirements for generic format
The generic format can satisfy the following requirements of the data preparer and the
publisher:
a) logical structure:
the generic format has to have a logical structure that can easily be revised;
b) style specification:
the logical elements in the generic format should be rendered in accordance with a style
specification for creating an appropriate reader’s format;
c) heterogeneous structures:
multimedia e-books may include heterogeneous structures such as mathematics,
chemistry and music notes according to the genre of contents. Those specific structures
should be imported to the generic format;
d) metadata:
the generic format should support some metadata to manage the e-book contents data.

The logical structure of generic format is described by using RELAX NG sche
