信息技术.元数据注册（MDR）.第31部分:数据规范注册的元模型

[中文适用范围]： 本文件提供了对 ISO/IEC 11179-3 中规定的元数据注册表 (MDR) 的扩展的规范，其中可以注册描述数据元素和相关概念（例如“数据元素概念”、“概念域”和“值域”）的元数据。本文件中的规范与 ISO/IEC 11179-3 中规范的相关条款一起提供了记录以下元数据的能力：a) 数据元素、度量单位和派生规则；b) 数据元素概念和相关对象类和属性；c) 概念域、概念域子集和值含义；d) 值域、值域子集、数据类型和允许值。本文件适用于制定数据表示、概念、含义和关系，供人和机器共享，与生成数据的组织无关。它不适用于机器级别的数据作为位和字节的物理表示。 [外文原描述]： This document provides a specification for an extension to a Metadata Registry (MDR), as specified in ISO/IEC 11179-3, in which metadata that describes data elements and associated concepts, such as “data element concepts”, “conceptual domains” and “value domains” can be registered. The specification in this document, together with the relevant clauses of the specification in ISO/IEC 11179-3, provides the ability to record metadata about: a) data elements, units of measure and derivation rules; b) data element concepts and associated object classes and properties; c) conceptual domains, conceptual domain subsets and value meanings; d) value domains, value domain subsets, datatypes and permissible values. This document is applicable to the formulation of data representations, concepts, meanings and relationships to be shared among people and machines, independent of the organization that produces the data. It is not applicable to the physical representation of data as bits and bytes at the machine level.
