标准范围

ISO/IEC 11179-31:2023本文档提供了元数据注册表(MDR)扩展的规范，如ISO/IEC 11179-3中所规定，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。本文件中的规范以及ISO/IEC 11179-3中规范的相关条款提供了记录以下方面的元数据的能力:a)数据元素、计量单位和推导规则；b)数据元素概念和相关的对象类和属性；c)概念域、概念域子集和价值含义；d)值域、值域子集、数据类型和允许值。本文档适用于人和机器之间共享的数据表示、概念、含义和关系的制定，独立于产生数据的组织。它不适用于在机器级别将数据物理表示为位和字节。

ISO/IEC 11179-31:2023 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.
