Overview

IEC TS 62768:2012 - Preparation and processing of source definitions for data element types - provides guidelines for product committees on how to prepare and submit Data Element Types (DETs) for inclusion in the IEC Component Data Dictionary (IEC CDD). The Technical Specification defines what source descriptions must appear in a committee’s own standard and what information should be sent to SC3D (the IEC maintenance body for product properties and classes) to enable formal checks, validation and publication in the IEC CDD.

Key Topics

• Scope and purpose: Clarifies the start-to-finish responsibilities of product committees and SC3D for standardizing DETs intended for computer-interpretable product descriptions.
• Source standard requirements: Specifies that each DET should be traceable to a reliable source standard (typically the relevant product standard) and be described consistently to avoid contradictory standards.
• Cooperation and responsibilities: Describes the collaborative workflow between domain experts (product committees) and information-structure experts (SC3D), including the recommendation to form a Maintenance Team (MT) when appropriate.
• Submission content and format: Outlines required information to send to SC3D (change requests), the form of presentation, preliminaries and formal checks that support inclusion in IEC CDD.
• Change management and validation: Covers procedures for validation, publication, maintenance and change control of DET entries in the IEC CDD.
• Supporting materials: Includes informative annexes - a template for DET definitions and an example of a source-publication annex and change request - to help committees prepare compliant submissions.
• IP and licensing: Reminds submitters about the applicable IEC license statement and the need to declare content exploitation rights for database publication.

Applications and Users

Who uses IEC TS 62768:2012:

• Product committees and developers of product and horizontal standards preparing DETs for machine-readable specifications.
• Standards managers and technical editors drafting the “Data Element Type definitions” annex in standards.
• SC3D and maintenance teams (MTs) responsible for processing, validating and publishing DETs in the IEC CDD.
• Data architects, PLM and catalog managers who rely on standardized DETs and IEC CDD content for interoperable product data exchange.

Practical uses:

• Enabling consistent, computer-interpretable product property definitions across IEC standards.
• Supporting integration with the IEC CDD for product catalogs, PLM systems and semantic interoperability initiatives.

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.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 62768, which is a technical specification, has been prepared by IEC technical committee
3: Information structures, documentation and graphical symbols.

1 Scope
This Technical Specification specifies how product committees, including committees
producing horizontal standards, intending to submit Data Element Types (DETs) for inclusion
in the IEC Component Data Dictionary (IEC CDD), should specify the source descriptions in
their own standard; and specify the information to be sent to SC3D for inclusion in IEC CDD.

3.2
(characteristic) property
defined parameter suitable for the description and differentiation of objects
Note 1 to entry: The term (characteristic) property (of an object) is not identical with the term data element type
used in IEC 61360. A data element type is a unit of data for which the identification, description and value
representation have been specified in the context of a dictionary, while the term (characteristic) property is used
for an occurrence of such a data element type in the context of a specification of an object. This distinction
makes it possible to qualify a property in an object specification and still refer to the same data element type
definition in the dictionary.

3.3
data element type
DET
unit of data for which the identification, description and value representation have been
specified

3.4
horizontal standard
standard on fundamental principles, concepts, terminology or technical characteristics,
relevant to a number of technical committees and of crucial importance to ensure the
coherence of the corpus of standardization documents
[SOURCE: IEC Guide 108:2006, 3.1]
3.5
product standard
standard that specifies requirements to be fulfilled by a product or group of products to
establish its fitness for purpose
Note 1 to entry: A product standard may include, in addition to the fitness-for-purpose requirements, directly or by
reference, aspects such as terminology, sampling, testing, packaging and labelling and, sometimes, processing
requirements.
Note 2 to entry: A product standard can either be complete or not, according to whether it specifies all or only a
part of the necessary requirements. In this respect, one may differentiate between standards such as dimensional,
material and technical delivery standards.

TS 62768  IEC:2012(E) – 7 –
4.2 Cooperation and responsibilities
Data Element Types (DETs) are used for computer interpretable specification of characteristic
properties of products, systems and components. “Computer interpretable” indicates that
formal requirements have to be fulfilled, from information technological view, with regard to
way the standardization of DETs is carried out.
The IEC Component Data Dictionary (IEC CDD, IEC 61360-4) is the IEC repository for DETs.
It is managed by SC3D Product properties and classes and their identification, of TC3
Information structures, documentation and graphical symbols. SC3D is responsible for
carrying out the last part of the standardization procedure that ultimately leads to the inclusion
of a DET in this repository. This includes all required formal checks of the DET, mentioned
above.
The beginning of the standardization process is the task of those committees that wish to
have their DETs included in the IEC CDD.
Experts involved in product committees have knowledge of the actual product properties (but
often limited interest in information technology); experts involved in SC3D have necessary
knowledge of how to handle the information (but cannot possibly have complete knowledge of
all product areas).
The standardization of DETs is therefore by necessity a cooperative task between the SC3D
and the actual committee. The committee is responsible for the supply of adequate source
descriptions for the DETs for further processing by SC3D. In many cases is it wise to set up a
specific MT to support the cooperation.
The committee supplying information for publication in the IEC CDD shall be aware of the
following statement:
By submitting content for storage, discussion, or publication in an IEC publication in
database form, the proposer declares that the submitted content may be exploited
according to the rules stated in the relevant license statement. No economic rights
[1]
(such as copyright or intellectual property rights) shall apply that restrict the above
use of the submitted content.
[1] Guide on Surveying the Economic Contribution of the Copyright-Based Industries, WORLD INTELLECTUAL
PROPERTY ORGANIZATION, Geneva 2003
NOTE The applicable License Statement is found in: End User License Agreement for IEC Component Data
Dictionary (CDD).
For the use of the information provided in a dictionary the following statement (appearing in
the database) applies:
All publications from IEC, independent of its representation or presentation form, are
generally intended for public use. Therefore the published content may be exploited
according to the rules stated in the relevant license statement.
Depending on a specific standard, there might be constraints for its full industrial use
influenced by associated patents. IEC runs a list on its homepage listing all those
published standards being partially affected by known patents, providing information on
how to proceed in such case.
IEC is responsible of the English and French variants of a dictionary. Further language
variants included in a database are under the responsibility of the relevant National
Committee. In some cases the French language variant may not be implemented by
decision of the French National Committee.
