信息技术 元数据的概念与使用 第26部分：表示 ISO/IEC 11179-3:2013 内容的 XML

[中文适用范围]： 本文件规定了符合ISO/IEC 11179-3:2013标准的表示结构在W3C XML Schema中的形式，适用于合规注册机构之间的内容交换。本文件所描述的模式将实现一种类与属性词汇体系，该体系与ISO/IEC 11179-3:2013中提出的概念模型相对应，并采用W3C XML Schema格式。该模式的目的在于支持合规元数据的交换，并验证注册机构之间交互的消息。本模式不用于在数据元数据与其所指数据一同传输时进行元数据通信。此外，本文件规定了用于将概念模型中的类、属性及关联映射为适合无歧义文档表示的有向无环图时所遵循的原则与惯例。 [外文原描述]： This document specifies the structure of ISO/IEC 11179-3:2013 representation in W3C XML Schema suitable for communication of content between compliant registries. The schema described in this document will implement a class and attribute vocabulary that matches the conceptual model presented in ISO/IEC 11179-3:2013 in W3C XML Schema format. The purpose of the schema is for the exchange of compliant metadata, and to support the validation of messages exchanged between registries. It is not intended for the communication of data element metadata alongside the data to which the metadata refers. The document specifes the schema and the principles and conventions that were followed to map classes, attributes, and associations of the conceptual model into an acyclic, directed graph suitable for an unambiguous document-based representation.
