22、-1:2015ISO 14817-1:2015(E)IntroductionBackgroundThis 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
23、maximize interoperability and facilitate information re-use across system interfaces.Vision statementThis 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
24、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 stat
25、ementThe 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 applicati
26、on; 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 in
27、consistently 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
28、 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 exchange
29、d 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 elem
30、ents 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 delivera
31、bles, particularly ISO 14813-2 and ISO 14813-3. 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 betwe
32、en 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 th
33、e submission by relevant users. Data dictionary entries are not limited to those generated by object oriented methodologies.Document overviewThis clause provides an overview of this International Standard. Clause 1 identifies the scope of this part of ISO 14817. Clause 2 identifies requirements for
34、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.vi ISO 2015 All rights reservedBS ISO 14817-1:2015ISO 14817-1:2015(E)Clause 6

Annex B specifies the naming conventions and the process for converting amo
36、ng various naming conventions (e.g. between the ITS descriptive name and the ASN.1 name). Annex C contains a listing of preferred data concepts within the ITS domain. Annex D contains the rules for representing data in a data model, along with examples.The Bibliography includes a list of documents r

38、 data dictionaries Part 1: Requirements for ITS data definitions1 ScopeThis part of ISO 14817 specifies the logical structure (framework) and the data content (substance) of intelligent transport systems (ITS) data dictionaries (DDs).Specifically, this part of ISO 14817 specifies the following: fram
39、ework used to identify and define all data concepts; meta-attributes used to describe, standardize and manage each of the data concepts defined within this framework; requirements used to record these definitions; naming conventions for the data concepts; a set of preferred data concepts within the
40、ITS domain; data modelling method for defining ITS data concepts, when used.DDs support data concepts derived from any number of international, regional or national system architecture methodologies and/or techniques. Common data formats and operating procedures will ease migration and interoperabil
41、ity between such approaches.A data concept registry is an electronic data dictionary that supports some additional features. The CIDCR refers to the specific implementation of an ITS data concept registry that is operated under the auspices of ISO/TC 204. The term “data concept registries” may refer
42、 to the CIDCR and/or any other national or regional data concept registry that chooses to conform to this part of ISO 14817.2 ConformanceThis part of ISO 14817 prescribes a conceptual model, not a physical implementation. An implementation of this part of ISO 14817 may use different data concepts, d
43、ifferent meta-attributes, or different data concepts and different meta-attributes; however, a conforming implementation of this part of ISO 14817 shall provide an unambiguous mapping to and from the physical implementation model and the conceptual meta-model defined by this part of ISO 14817.Region
44、al and National DDs have the option of adopting data concept definitions from the CIDCR, but are not required to do so.Table 1 indicates the conformance requirements of data concept registries and data dictionaries.INTERNATIONAL STANDARD ISO 14817-1:2015(E) ISO 2015 All rights reserved 1BS ISO 14817
