信息技术 - 元数据登记（MDR） - 第2部分:分类

[中文适用范围]： 本文件补充了ISO/IEC 11179-3的内容，描述了分类方案的注册以及如何使用这些分类方案对元数据注册数据库（MDR）中的项目进行分类。任何元数据项都可以被指定为可分类项，以便对其进行分类，包括对象类、属性、表示形式、概念域、值域、数据元素概念和数据元素本身。本文件没有确立特定的分类方案作为权威。对于特定的分类方法学或认识论的批准也超出了本文件的范围。这些问题由其他标准委员会处理，并且通常根据特定领域的讨论进行定制。元数据注册数据库可以建立自己的分类方案，而其他标准委员会正在制定或已经制定了用于分类的标准语言和/或技术。每个注册机构（如ISO/IEC 11179-6中所述和规定），可以根据其认为适当的分类方案、结构和内容对可分类项进行分类。在记录可分类项目的分类方面，注册机构可以使用本文件涵盖的原则、方法、程序和属性。 [外文原描述]： This document compliments ISO/IEC 11179-3 by describing registration of classification schemes and using them to classify registered items in an MDR. Any metadata item can be made a Classifiable_Item so it can be classified, which can include object classes, properties, representations, conceptual domains, value domains, data element concepts and data elements themselves. This document does not establish a particular classification scheme as pre-eminent. Sanction of a particular taxonomic approach and/or a particular epistemology is also beyond the scope of this document. These are addressed by other standards committees and/or tend to be tailored to a particular domain of discourse. The MDR can establish its own classification schemes, and other standards committees are developing or have developed normative languages for use in classification and/or particular techniques and structures that can be accommodated by this document. Each registration authority, as described and specified in ISO/IEC 11179-6, can classify classifiable items according to the classification schemes, structures and content that it deems appropriate. In documenting the classification aspects of classifiable items, the registration authority can use the principles, methods, procedures and attributes covered in this document.
