FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61360-2 has been prepared by subcommittee 3D: Data sets for
libraries, of IEC technical committee 3: Information structures, documentation and graphical
symbols.
This second edition cancels and replaces the first edition published in 1998 and constitutes a
technical revision
The text of this standard is based on the following documents:
FDIS Report on voting
3D/92/FDIS 3D/95/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A and B are for information only.

with associated classification scheme for electric components:
– Part 1 : Definitions – Principles and methods
– Part 2 : EXPRESS dictionary schema
– Part 3 : Maintenance and validation procedures
– Part 4 : IEC reference collection of standard data element types, component classes and

– Part 5 : Extensions to the EXPRESS dictionary schema .

INTRODUCTION
The common ISO/IEC dictionary schema presented here is based on the intersection of the
scopes of the following standards:
– IEC 61360-1
– ISO 13584-42
Relevant parts of the scope clauses of these standards include the following:
IEC 61360-1:
"This part of IEC 61360 specifies the principles to be used for defining technical data element
types with associated classification schemes needed to describe fully electric components,
including electronic and electromechanical components and materials used in electro-technical
equipment and systems."
ISO 13584-42:
" This part of ISO 13584 specifies:
• the attributes that shall be provided by library suppliers to describe the families and
properties of parts. These attributes are part of the content of their parts library and shall
be stored in the dictionary of the user library;
• the specifications of these attributes in the EXPRESS information model that provides for
the exchange of such dictionary data".
IEC SC 3D and ISO TC 184/SC4 agreed NOT to change and/or modify the presented EXPRESS
model independent of each other in order to guarantee the harmonization and the reusability of
the work of both committees.
Requests for amendments should therefore be sent to both committees. These requests
should be adopted by both committees before modifying the EXPRESS information model.

Part 2: EXPRESS dictionary schema
1 General
1.1 Scope
This part of IEC 61360 presents a common ISO/IEC dictionary schema based on the
intersection of the scopes of two base standards IEC 61360-1 and ISO 13584-42.
The presented EXPRESS model represents a common formal model for the two standards and
facilitates a harmonization of both.
The IEC 61360-2 standard forms the master document. ISO 13584-42 contains a copy of
the IEC 61360-2 EXPRESS model in an informative annex
This standard provides a formal model for data according to the scope as given in the
publications cited above, and thus provides a means for the computer-sensible representation
and exchange of such data.
The intention is to provide a common information model for the work of IEC TC 3D and
ISO TC 184/SC4, thus allowing for the implementation of dictionary systems dealing with data
delivered according to either of the standards elaborated by both committees.
Two schemas are provided in this part of IEC 61360 defining the two options that may be
selected for an implementation. Each of these options is referred to as a conformance class.
• The ISO13584_IEC61360_dictionary_schema provides for modelling and exchanging
technical data element types with associated classification scheme but without modelling
the definitions of the terms used in the data element type definitions. It constitutes
conformance class 1 of this part of IEC 61360.
• The ISO13584_IEC61360_language_resource_schema provides resources for permitting
strings in various languages. It has been extracted from the dictionary schema, since it
could be used in other schemata. It is largely based on the support_resource_schema
from ISO 10303-41: STEP part 41: "Fundamentals of Product Description and Support",
and can be seen as an extension to that. It allows for the usage of one specific language
throughout an exchange context (Physical File) without the overhead introduced when
multiple languages are used.
When used together with ISO 10303-21, each schema defines one single exchange format.
The exchange format defined by conformance class 1 is fully compatible with the ISO 13584
series.
The exchange format defined by conformance class 2 also provides for exchanging the
definitions of the terms used in the defining of data element types and their associated
classification sc
