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/d irectives).
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

Introduction
Background
This document has been developed by ISO/TC 204 in order to provide a framework for the
documentation and registration of data that passes through system interfaces within the Intelligent
Transport Systems (ITS) domain. It is designed to maximize interoperability and facilitate information
re-use across system interfaces.
Vision statement
This International Standard envisions a harmonized approach to ITS data and interfaces to promote
maximum interoperability of data within the ITS sector by the creation and maintenance of the
Central ITS Data Concept Registry (CIDCR), which are supported by interface and application-specific
ITS data dictionaries, created and maintained in a common and interoperable form, and to ensure
the minimization of duplication by clear rules for data concept definition and data concept registry
management.
Mission statement
The mission is to develop tools that will promote a holistic, integrated approach involving vehicle
technology, infrastructure, and the road user to increase transport safety and efficiency. Specifically,
this standard defines the principles and concepts, scope, field of application, rules and procedures, and
definition and concept of operation for the CIDCR and ITS functional data dictionaries. Furthermore,
this standard also makes provision for the migration of data concepts from ITS functional data
dictionaries to the CIDCR to maximize interoperability and minimize proliferation of similar (but
inconsistently defined) data concept entries.
This International Standard defines the framework, formats, and procedures used to define information
and information exchanges within the ITS sector. The standard is designed to be used by the ITS
community at large, but should be of special interest to application developers, equipment providers,
and data concept registry managers.
ISO 14817-1 specifies a set of meta-attributes for ITS data concepts, as well as associated conventions
and schemes that enable the description, standardization and management of all exchanged ITS
data. Through consistent use of these common structures and associated conventions and schemes,
interchange of data and information among the various ITS functional subsystems via their specific
application systems can be maximized. This International Standard also supports re-use of data
elements and other data concepts across various ITS functional subsystems and their specific
application systems.
The formats and processes defined within this International Standard are consistent with
implementation(s) of the ISO ITS System Architecture defined in the ISO 14813 Standardization
deliverables, particularly ISO 14813-2 and ISO 14813-2. This does not preclude the application of
data concept registries using alternative international, regional or national system architecture
methodologies or techniques, indeed, common formats and processes will ease migration and
interoperability between such approaches.
The ITS data concepts that populate the CIDCR or data dictionary may originate from a Computer-
Aided Software Engineering (CASE) tool implementation of the ISO 14813 ITS Reference Architecture,
from International Standards for ITS, from national implementations for ITS, or from the submission
by relevant users. Data dictionary entries are not limited to those generated by object-oriented
methodologies.
Document overview
This clause provides an overview of this document. Clause 1 identifies the scope of this document.
Clause 2 specifies the conformance tests that a data concept must pass to be assigned an arc under the
“common-data” arc. Clause 3 identifies references required for proper implementation of this document.
Clause 4 defines terms used and Clause 5 lists the abbreviations. Clause 6 declares the structure of

the centralized ITS naming tree and Clause 7 identifies management structure for adding new arcs
underneath the centralized ITS naming tree.

Annex B is informational and provides answers to frequently asked questions.

4 Conformance
4.1 General
Prior to standardizing an arc assignment to any data concept under the joint “its” arc, the developer
of the data concept shall enter the data concept into the CIDCR so that it reaches the quality level of
“recorded” or higher. In addition, it is recommended that the following conditions be met:
NOTE ISO 14817-2 defines the “recorded” level as “Indicates that the data concept has syntactically valid
entries for all mandatory meta-attributes and passes all defined automated checks for the data concept type”.

4.2 Contextual name
Verify that the name is descriptive of the data concept being defined.
4.3 Parent object class
Verify that the parent object class properly identifies the object class that the data concept describes
when this meta-attribute is required.
4.4 Definition
Verify that the definition unambiguously describes the data concept meaning.
4.5 Context
Verify that the context properly references the correct module or dictionary document.
4.6 Data type
Verify that the data type conforms to the rules of ISO 14817-1:2015, 7.4.1.
