INTERCHANGE FORMAT FOR E-DICTIONARIES
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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 62605 has been prepared by technical area 10: Multimedia e-

publishing and e-book technologies, of IEC technical committee 100: Audio, video and

multimedia systems and equipment.

This second edition cancels and replaces the first edition published in 2011. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition.
a) Ref element is added to facilitate cross reference between entries.

b) A new version of LeXML format, which is one of the base formats of the first edition, has

been expanded and becomes Annex B. (The existing format becomes Annex A.)

INTRODUCTION

Markets for multimedia e-books 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, interchange format and reader’s format.

The submission format supports an interaction between authors and data preparers. The

reader’s format depends on e-publishing equipment. The interchange format provides 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.

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 IEC.

Information may be obtained from:
Sharp Corporation,
22-22 Nagaike-cho,
Abeno-ku,
Osaka 545-8522,
Japan

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. IEC shall not be held responsible for

identifying any or all such patent rights.

ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of

patents relevant to their standards. Users are encouraged to consult the data bases for the

most up to date information concerning patents.

INTERCHANGE FORMAT FOR E-DICTIONARIES
1 Scope

This International Standard specifies the interchange format for e-dictionaries among

publishers, content creators and manufacturers.
This International Standard does not address the following aspects:
• data formats for reading devices;
• elements necessary for final print reproduction only;
• rendering issues related to physical devices;
• security issues such as DRM for documents.
2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and

are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any
amendments) applies.

IEC TS 62229:2006, Multimedia systems and equipment – Multimedia e-publishing and

e-book – Conceptual model for multimedia e-publishing
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
manufacturer

It should be noted that the role of manufacturers of e-dictionary hardware and software

overlaps that of the publisher in Figure 1. Therefore, a slightly modified model will be

assumed for this International Standard, as shown in Figure 2.

Author <--(1)--> Data preparer <--(2)--> Publisher (manufacturer) --(3)--> Reader

IEC
Figure 2 – Contents creation/distribution model (modified)

This International Standard specifies the interchange format between data preparers and

publishers, i.e. a format for (2) in Figure 2, though it may be used as a reader's format.

4.2 Requirements for interchange format for e-dictionaries
An interchange format for e-dictionaries needs to address the following.

• Description of keywords, links from the keywords to entries (link data) and the order of the

entries.

• Description of articles for each entry (entry data). This includes text, image, and other

multimedia functionalities generally required for e-books.

• Description of bibliographical data and other data. This should include the name of the

author and the publisher, the title of the content and the explanatory note. The relationship

between these concepts is visually represented in Figure 3.
• Description of contents written in various languages.

5 File formats

This International Standard defines two XML-based formats. One is based on XMDF (as

described in IEC 62448:2013, Annex B) and LeXML. The format is hereafter called
XMDF-LeXML format. The other is based solely on LeXML 3.0. They are presented in
Annex A and Annex B, respectively.

NOTE LeXML is proposed by Digital ASSIST Ltd. Its original specifications are found at

http://www.d-assist.com/index.html (in Japanese).

Annex A
(normative)
XMDF-LeXML format
A.1 General

The XMDF-LeXML format is an interchange format for e-dictionaries multimedia e-book data

interchange, targeted at data preparers and publishers rather than the reader, with an

emphasis on mobile devices as a target platform. Much like HTML, this format does not split

the document in fixed pages, but determines the layout according to the viewer device’s

display size, the font in use, and so on. In this annex, such contents will be referred to as

flowing content, as opposed to paged content.
A.2 Overview of the format’s structure

Flowing contents are usually composed of several concatenated flows. This annex makes no

particular requirement concerning the way the flowing content should be split into individual

flows. This decision is left to the data preparer, to accommodate the various types of contents.

For instance, a newspaper may have one flow per article, a novel one per chapter, and so on.

It is also possible not to split the content, and to have only one flow. However, it should be

noted that particularly large flows, or an extremely large number of flows, may impact on

runtime performance, depending on the specific version of the viewer in use, the available

memory, and so on.
The XML tree structure of the format is shown in Figure A.1.

– 12 – IEC 62605:2016 © IEC 2016

The actual contents of each flow, in other words, what will be displayed by the viewer, is

recorded in the object instance. The object instance is registered in object_entry, and

associated with an ID number and other auxiliary data, turning it into playable/displayable

data. Flow_data determines its content by pointing at such registered objects. In addition,

information on functionalities such as page link is recorded in event_info.

The main part of Annex A is generic, and may be used for any country and language.

However, some parts may have language specific behavior. Localization-related issues are

detailed in Clause A.6.
A.3 Elements and attributes
A.3.1 General

The different types of values that may be used in the various elements or attributes are

explained below. The elements and attributes detailed below will be valid throughout this

annex, and will be referenced by other constructs. In the following explanations, alphanumeric

characters refer to numerals from 0 to 9 and alphabetic letters from a to z and A to Z.

A.3.2 Page_ID

Page_ID specifies a unique identification number for the flow data of the flowing contents. It is

a string starting by the "PG" characters, followed by alphanumeric characters.
Example:

A.3.3 Object_ID

Object_ID specifies a unique identification number for objects used in the flowing contents. It

is a string starting by the "OB" characters, followed by alphanumeric characters.

Example:

A.3.4 Char_ID

Char_ID specifies an identification number for positions (character strings, etc.) within

...
