Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 9973 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 24, Computer graphics, image processing and environmental data representation.
This third edition cancels and replaces the second edition (ISO/IEC 9973:2006), which has been
technically revised.

Introduction
This International Standard provides a set of procedures for managing the International Register
of Items. In this context, items are members of classes defined within the standards developed by
ISO/IEC JTC 1/SC 24 that may be registered. The set of procedures specified in this International
Standard is equally applicable to any standard that includes a provision for registering items in the
International Register of Items.
Standards that wish to use the International Register of Items may have certain classes of items in
common that are allowed to vary across implementations of those standards. There is a strong incentive
for implementations using the same registered items to reference them in the same way. Each such
standard has the potential to provide for registration of items of certain classes and expressly identifies
those classes of items that may be registered. When such a standard is published, those classes of items
identified for registration are automatically added to the International Register of Items.
The procedures in this International Standard are used in preparing, maintaining, and publishing the
International Register of Items. The register includes current classes of items from relevant International
Standards whose content can be extended through registration. The classes of items are listed within the
register and therefore maintained separately from this International Standard. The register also serves as
a means to inform all concerned of items already registered and of the specific identifiers assigned to them.
Registration provides identification for an item but should not be regarded as a standardization procedure.
Annex A identifies the information needed in submitting item proposals. Annex B contains example
proposal forms. Annex C contains language binding guidelines for submission of registration proposals.
Annex D contains encoding guidelines for submission of registration proposals.

— spatial and environmental concepts, and
— profiles of relevant standards.

4 Concepts
4.1 Overview
Standards that include registration provisions, as specified by this International Standard, are supported
by the International Register of Items. The International Register of Items provides the following features:
— a register of identifiers and meanings that may be shared between related standards,
— new instances of concepts in the related standards to be specified by registration, and
— a repository where both standardized and registered items may be browsed or searched.
This International Standard specifies procedures that manage the International Register of Items,
which is organized into sections. The International Register of Items is maintained by the registration

authority. Proposals related to the International Register of Items are submitted by sponsoring
authorities, processed by the registration authority and approved by the relevant approval body.
4.2 Registration authority
4.2.1 Appointment of a registration authority
The registration authority for this International Standard is established in accordance with ISO/IEC
Directives, Part 1, Annex H and is approved by the ISO Technical Management Board as par
