ISO 14817-1:2015规定了智能交通系统（ITS）数据字典（DDs）的逻辑结构（框架）和数据内容（实质）。 具体而言，ISO 14817的本部分规定了以下内容: -用于识别和定义所有数据概念的框架； -用于描述、标准化和管理本框架中定义的每个数据概念的元属性； -用于记录这些定义的要求； -数据概念的命名约定； -ITS领域内的一组首选数据概念； -用于定义其数据概念的数据建模方法。 DDs支持从任何数量的国际、区域或国家系统架构方法和/或技术中衍生出的数据概念。 通用数据格式和操作程序将简化这些方法之间的迁移和互操作性。 数据概念注册是一个电子数据字典，支持一些附加功能。CIDCR是指在ISO/TC 204的支持下运行的ITS数据概念注册的具体实施。术语“数据概念注册”可指CIDCR和/或选择符合ISO 14817本部分要求的任何其他国家或地区数据概念注册。

ISO 14817-1:2015 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: - framework 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 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 interoperability 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 to the CIDCR and/or any other national or regional data concept registry that chooses to conform to this part of ISO 14817.
