带有相关分类表的标准数据元类型.第1部分:定义,原则和方法

[中文适用范围]： IEC 61360 的这一部分指定了属性和相关属性的定义原则，并解释了使用 IEC 61360-2 中提供的适当数据结构表示口头定义的概念的方法。它还规定了从一组类别中建立分类层次结构的原则，每个类别代表电工领域或与电工技术相关的领域中的一个技术概念。本文档的使用有助于通过定义的结构来交换技术数据，以便以计算机可感知的形式交换信息。每个要交换的属性都有明确定义的含义和一致的命名，相关时有定义的值列表、规定的格式和所有定量值的定义的测量单位。还规定： a) 通过版本和修订号控制属性定义的变更； b) 包含注释和评论，以澄清和帮助定义的应用； c) 说明定义和值列表的来源； d) 相关数字和公式。注：IEC TC 和 SC 或其他组织可以将此文件作为开发自己词典的基础。与信息技术基础设施相关的主题超出了本文档的范围，例如：安全性；数据库锁定机制；访问权限管理。 [外文原描述]： IEC 61360-1:2017 specifies principles for the definition of the properties and associated attributes and explains the methods for representing verbally defined concepts with appropriate data constructs available from IEC 61360-2. It also specifies principles for establishing a hierarchy of classification from a collection of classes, each of which represents a technical concept in the electrotechnical domain or a domain related to electrotechnology. This fourth edition cancels and replaces the third edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - support of advanced constructs such as · conditions and constraints, · blocks, · cardinality, · polymorphism, · generic and restricted enumerations, and · mapping; - extended list of data types; - harmonization with IEC 62656-1; - support of IEC TS 62720 and of coded units; - harmonization of semantic and administrative data among the various information objects; - use of UML for data modelling; - enhanced definitions and descriptions; - introduction of examples of higher level constructs such as block, cardinality, or polymorphism as guidance for the user of the IEC 61360 series. IEC 61360-4, IEC reference collection of standard data element types and component classes, can be accessed from IEC CDD (Common Data Dictionary) Free access to Database. The database contains the IEC reference collection of classes and associated characteristic properties (data element types or DETs) of electric/electronic components including materials, geometry and features used in electrotechnical equipment and systems. The dictionary and database follow the methodology of Part 1 of IEC 61360 and the information model of Part 2. IEC 61360-1:2017 has the status of a horizontal standard in accordance with IEC Guide 108 .
