Intelligent transport systems — ITS central data dictionaries — Part 2: Governance of the Central ITS Data Concept Registry

ISO 14817-2:2015 specifies the registration process to enter data concepts into the Central ITS Data Concept Registry (CIDCR). The CIDCR is designed to include data concepts that conform to ISO 14817-1. These data concepts may be derived from the system architecture defined in ISO 14813, but may also support data concepts using alternative International, Regional or National System Architecture methodologies or techniques.

Introduction
Background
This International Standard 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 concepts to promote maximum
interoperability of data within the ITS sector by the creation and maintenance of the “Central ITS
Data Concept Registry” (CIDCR), 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 International Standard defines the principles and concepts; scope; field of application; rules and
procedures; definition and concept of operation for the CIDCR and ITS functional data dictionaries; and
makes provision for the migration of data concepts from ITS functional data dictionaries to the CIDCR
so as 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. This International 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.
This International Standard 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 parts that discuss core TICS reference architecture and example elaboration.
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.
Overview of Central ITS Data Concept Registry
The scope of ITS applications covers numerous ISO/TC 204 functional areas as well as national and
regional ITS organizations, each having an established group of stakeholders. The international
integration of ITS applications is one of the major development issues, so that data defined and
gathered in one of these functional areas (e.g. traffic management, traveller information) can be applied

ISO 14817-2:2015(E)

in another. For this type of interoperability the definition of data that can persist across different
functional areas must be standardized. The CIDCR meets this requirement.
The CIDCR supports the standardization and harmonization of data concepts (e.g. data elements) from
different stakeholder groups. The ITS stakeholder community is large and diverse as evidenced by
the number of working groups within ISO/TC 204 and the number of national or regional ITS bodies
participating. The definition of key data elements will arise from numerous sources. Moreover different
groups will have an interest in the definition of the same data concept, which could lead to the prospect
of duplicate or similar definitions being developed. The CIDCR will assist in promoting the reuse of
previously defined data and minimizing data duplication.
The complete ITS distributed system will be very large, both in geographic extent and in the number
and diversity of the application areas, inevitably leading to the independent development of sub-
systems. In this context, a second major purpose of the CIDCR is to document and register interface
dialogues. This process provides the main foundation for interoperability, by also focusing on those
data concepts which cross an interface, but which are not necessarily harmonized throughout ITS. The
semantics of data concepts may be documented by recording the associations of the data models in
which they participate.
The operational concept of the data concept registration is described in the following subclauses. See
Annex A for specific procedural details.
Document overview
This clause provides an overview of this International Standard. Clause 1 identifies the scope of this
part of ISO 14817. Clause 2 identifies requirements for conformance to this part of ISO 14817. Clause 3
identifies references required for proper implementation of this part of ISO 14817. Clause 4 defines
terms used in this part of ISO 14817 and Clause 5 lists the abbreviations.
The requirements for the CIDCR begin in Clause 6 with an overview of the concept of operations. A
framework describing the registration of different types of data concepts in the CIDCR and the
registration status levels are presented.
Clause 7 identifies the management of the CIDCR and identifies the major actors that interface with
the registry and their responsibilities. Clause 8 then identifies the administrative meta-attributes
associated with each data concept.
The annexes to this part of ISO 14817 describe the specific details for implementing the requirements
introduced in Clause 6 to Clause 8. Annex A details when specific meta-attributes are required for each
type of data concept. Annex B defines the process used for quality control within the CIDCR, Annex C
defines the registration status levels and Annex D defines the rules for version control. Finally, Annex E
defines guidelines for harmonization.
The Bibliography includes a list of documents related to this part of ISO 14817.

Part 2:
Governance of the Central ITS Data Concept Registry
1 Scope
This part of ISO 14817 specifies the registration process to enter data concepts into the Central ITS
Data Concept Registry (CIDCR).
The CIDCR is designed to include data concepts that conform to ISO 14817-1. These data concepts may
be derived from the system architecture defined in ISO 14813, but may also support data concepts
using alternative International, Regional or National System Architecture methodologies or techniques.
2 Conformance
This part of ISO 14817 prescribes a conceptual model, but not a physical implementation. Therefore, the
meta model need not be physically implemented exactly as specified. However, it should be possible to
map unambiguously to and from the implementation and the meta model.
A conforming implementation shall support all processes defined by this part of ISO 14817.
3 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are

Figure 1 — CIDCR operational framework
For each of these elements, Figure 1 also lists their key functions. For data dictionaries, the CIDCR,
and the applications it further identifies the key stakeholders or stakeholder groups that participate
in or manage their operations. Finally, Figure 1 illustrates the information exchanged between these
operational elements.
The ITS data dictionaries contain data concepts based on information flows documented in an ITS
Architecture.
NOTE There may be multiple architectures, each with multiple versions that are referenced.
The data dictionaries in Figure 1 may be developed, for example, by ISO/TC 204 or regional or National
“Standards Development Organizations” (SDOs), public agencies, or private companies. These data
dictionaries are the responsibility of their respective SDOs, regional or National bodies. Each data
dictionary shall be associated with a data steward and/or data submitter, using the process defined
in this part of ISO 14817, to submit data concepts from their respective data dictionaries to the CIDCR.
Furthermore, these data dictionaries should use registered data concepts from the CIDCR rather than
invent new data concepts. The use of such registered data concepts will help to avoid redundancy in
data concepts.
The CIDCR shall be the repository for submitted data concepts. Through the efforts of the data stewards,
the registrar and the CIDCR change control committee (CCC) support identification of harmonization
opportunities, recommendations for harmonization, and promotion of data concepts to higher quality
levels where warranted. Finally, the CIDCR can provide data concepts to developers and other users for
use in ITS applications.
Developers and other users should use data concepts from the CIDCR at the highest (“Preferred”) quality
level. The data concepts at this level are described unambiguously, harmonized across ITS sectors, and
are considered representative of published data standards.
Table 1 presents a summary of the distinguishing characteristics between a data dictionary and the
CIDCR.
