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.

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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is

claimed that compliance with this document may involve the use of patents.
Sony Corporation has informed IEC that it has patent applications or granted patents.
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

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
[IEC 62229, 3.2]
62448 © IEC:2009(E) – 9 –
3.2
data preparer

[IEC 62229, 3.3 modified]
3.3
publisher
organization or person that issues and distributes an e-book

[IEC 62229, 3.4]
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.
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.

– 10 – 62448 © IEC:2009(E)
5 Notation
The logical structure of generic format is described by using RELAX NG schema,

ISO/IEC 19757-2.
6 Logical structure
The logical structure of generic format: ebook-g, provides a simple and extensible format

ebook-g-core and existing and actually employed formats bbebxylog and xmdf. The structures

of bbebxylog and xmdf are shown in Annex A and Annex B, respectively.

Annex A
(normative)
BBeB Xylog Format
A.1 General
This annex specifies the bbebxylog format mentioned in Clause 6.

This format is intended to be used for two kinds of users, that is, the e-Book contents
producer and the related tool developer. Those who produce contents can use this
specification as a generic contents data storage format based on the international standard
specification. The related tool developer can use it as a reference to decide on the
specification for the display equipment and to define the conversion rule between this
specification and the other data forms such as any types of XML or HTML.
The feature of this specification specified in this annex includes the following:
a) "expression of book on paper" concerning two screens layout and modified characters, etc.
b) "expression of digital" such as sound, page jump and interactive action, etc.
The elements necessary for the above-mentioned expressions and their smooth operations
are defined in this specification.

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.
International Standard IEC 62448 has been prepared by technical area 10: Multimedia e-
publishing and e-book, of IEC technical committee 100: Audio, video and multimedia systems
and equipment.
This second edition cancels and replaces the first edition, published in 2007 and constitutes a
technical revision.
The main changes with respect to the previous edition are listed below.
• Addition of Annex B – XMDF XML format
• Related changes in Clauses 2 and 6.
This bilingual version, published in 2009-06, corresponds to the English version.

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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is
claimed that compliance with this document may involve the use of patents.
Sony Corporation has informed IEC that it has patent applications or granted patents.
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.

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
[IEC 62229, 3.2]
62448 © IEC:2009 – 9 –
3.2
data preparer
organization or person that prepares an e-book; an editor is an example of a preparer
[IEC 62229, 3.3 modified]
3.3
publisher
organization or person that issues and distributes an e-book
[IEC 62229, 3.4]
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.
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.

– 10 – 62448 © IEC:2009
5 Notation
The logical structure of generic format is described by using RELAX NG schema,
ISO/IEC 19757-2.
6 Logical structure
The logical structure of generic format: ebook-g, provides a simple and extensible format
ebook-g-core and existing and actually employed formats bbebxylog and xmdf. The structures
of bbebxylog and xmdf are shown in Annex A and Annex B, respectively.

7 Semantics
Elements of ebook-g-core should be rendered in accordance with appropriate style
specifications. Actual style specifications by style languages, for example XSL or DSSSL, are
outside the scope of this standard.
The contents of meta-g.rnc, table.rnc and figure.rnc are not specified within an architecture of
the ebook-g-core.

Annex A
(normative)
BBeB Xylog Format
A.1 General
This annex specifies the bbebxylog format mentioned in Clause 6.
This format is intended to be used for two kinds of users, that is, the e-Book contents
producer and the related tool developer. Those who produce contents can use this
specification as a generic contents data storage format based on the international standard
specification. The related tool developer can use it as a reference to decide on the
specification for the display equipment and to define the conversion rule between this
specification and the other data forms such as any types of XML or HTML.
The feature of this specification specified in this annex includes the following:
a) "expression of book on paper" concerning two screens layout and modified characters, etc.
b) "expression of digital" such as sound, page jump and interactive action, etc.
The elements necessary for the above-mentioned expressions and their smooth operations
are defined in this specification.
