Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

Introduction
ISO/TC 204 has defined several documents that require globally unique identifiers to reference specific
items of interest (e.g. protocols, ITS applications, organizations). Items that need to be identified can
be registered in the Registry of Intelligent Transport System Items (RITSI), where they are assigned a
formal identifier. RITSI is designed in an open format such that:
— documents, including those developed outside of ISO, can:
— define data elements that reference RITSI registers as their value domain specification, and
— include informative statements that indicate the identifier that has been assigned to a specific
item;
— new items can be recorded in a timely fashion;
— the listing of registered items can be browsed and searched.
This document is designed to be used by the Intelligent Transport Systems (ITS) community at large
but is particularly directed at application developers and equipment providers.
This document specifies the procedures used to manage RITSI. The document is presented as follows:
— Clause 5 provides an overview of the document and the concepts used;
— Clause 6 defines the attributes that are used to characterize item classes;
— Clause 7 defines attributes that are used to characterize registered items;
— Clause 8 defines the information and rules related to requests that are submitted;
— Annex A provides the request form for use for all requested changes to the registers maintained
according to the rules defined by this document.

5 Concepts
5.1 Purpose
Within information exchanges, there is often a need to reference an entity of interest (e.g. a country, an
organization, a document, a protocol) unambiguously and concisely. One way to achieve this is to define
an identifier, which is a concise expression (e.g. an integer value) that is used to represent the item of
interest. The identifier can be an integer, a hierarchical structure (e.g. an ASN.1 OBJECT IDENTIFIER) or
any other concise representation of a more complex concept (e.g. a two-character country code).
The association of an identifier with a specific item is provided with the use of a register (i.e. a listing).
The register is presented as a table with columns representing different attributes (e.g. the name of
the item) and
