标准范围

基于ISO/IEC 11179的元数据注册表(MDR)(以下称为“注册表”)是用于管理可共享数据的工具；关于数据的全面、权威的参考信息来源。它通过记录和传播数据标准来支持标准化和协调进程，从而促进各组织和用户之间的数据共享。它提供了指向引用数据元素的文档和使用数据元素的信息系统的链接。当与信息数据库结合使用时，注册表使用户能够更好地了解所获得的信息。注册表本身不包含数据。它包含清晰描述、清点、分析和分类数据所必需的元数据。它提供了对数据单位的含义、表示和识别的理解。该标准标识了需要可用于确定要在系统之间共享的数据元素(DE)的含义的信息元素。ISO/IEC TR 20943-1:20 03的目的是描述一组在注册表中一致注册数据元素及其属性的程序。ISO/IEC TR 20943-1:20 03不是数据输入手册，而是用于概念化数据元素及其相关元数据项的用户指南，目的是始终如一地建立高质量的数据元素。组织可以根据需要调整和/或添加这些程序。ISO/IEC TR 20943-1:20 03的范围限于数据元素的相关项:数据元素标识符、特定上下文中的名称和定义以及示例；数据元素概念；概念域及其价值意义；以及具有允许值的值域。在ISO/IEC 11179元数据注册中心中注册代码集和其他值域时，有一个选择。一些注册机构将这些集合视为值域，而另一些注册机构将它们视为数据元素。出于ISO/IEC TR 20943-1:20 03的目的，除非明确说明，否则选择始终将集合视为数据元素。做出这种选择是为了帮助说明注册许多不同种类的数据元素的方式，包括将标准代码集注册为数据元素的示例。

An ISO/IEC 11179-based metadata registry (MDR) (hereafter referred to as a "registry") is a tool for the management of shareable data; a comprehensive, authoritative source of reference information about data. It supports the standardization and harmonization processes by recording and disseminating data standards, which facilitates data sharing among organizations and users. It provides links to documents that refer to data elements and to information systems where data elements are used. When used in conjunction with an information database, the registry enables users to better understand the information obtained.

A registry does not contain data itself. It contains the metadata that is necessary to clearly describe, inventory, analyze, and classify data. It provides an understanding of the meaning, representation, and identification of units of data. The standard identifies the information elements that need to be available for determining the meaning of a data element (DE) to be shared between systems.

The purpose of ISO/IEC TR 20943-1:2003 is to describe a set of procedures for the consistent registration of data elements and their attributes in a registry. ISO/IEC TR 20943-1:2003 is not a data entry manual, but a user's guide for conceptualizing a data element and its associated metadata items for the purpose of consistently establishing good quality data elements. An organization may adapt and/or add to these procedures as necessary.

The scope of ISO/IEC TR 20943-1:2003 is limited to the associated items of a data element: the data element identifier, names and definitions in particular contexts, and examples; data element concept; conceptual domain with its value meanings; and value domain with its permissible values.

There is a choice when registering code sets and other value domains in an ISO/IEC 11179 metadata registry. Some Registration Authorities treat these sets as value domains, and others treat them as data elements. For the purposes of ISO/IEC TR 20943-1:2003, the choice will always be to treat the sets as data elements unless explicitly stated. This choice is made to help illustrate the way to register many different kinds of data elements, including examples for registering standard code sets as data elements.
