ISO/IEC 11179-2:20 05重述并阐述了ISO/IEC 11179-3:20 03用于在元数据注册表（MDR）中注册分类方案和对管理项目进行分类的程序和技术。所有类型的被管理项都可以被分类，包括对象类、属性、表示、值域和数据元素概念，以及数据元素本身。ISO/IEC 11179-2:20 05开发了一组原则、方法和过程，用于指定（至少）记录各种类型的被管理项和一个或多个分类方案之间的关联所需的内容。这包括分类方案及其内容的名称、定义和其他方面。这些可以通过使用一组属性来捕获。特定属性在ISO/IEC 11179-2:20 05，以及这些属性的内容的结构。用户可以根据需要扩展属性集。附加信息可以伴随分类法或本体；例如，提供可应用于对象类、属性或表示分类群的建议限定符集合，以更充分地限定特定管理项的分类。ISO/IEC 11179-2:20 05总结了ISO/IEC 11179-3:20 03中规定的基本属性和型号。

ISO/IEC 11179-2:2005 restates and elaborates on the procedures and techniques of ISO/IEC 11179-3:2003 for registering classification schemes and classifying administered items in a metadata registry (MDR). All types of administered items can be classified, including object classes, properties, representations, value domains, and data element concepts, as well as data elements themselves.

ISO/IEC 11179-2:2005 develops a set of principles, methods, and procedures for specifying what is needed (at a minimum) to document the association between the various types of administered items and one or more classification schemes. This includes the names, definitions, and other aspects of the classification scheme and its contents. These can be captured through the use of a set of attributes. Particular attributes are specified in ISO/IEC 11179-2:2005, along with a structure for the contents of these attributes. Users may extend the set of attributes as necessary. Additional information may accompany a taxonomy or ontology; for example, to provide a suggested set of qualifiers that could be applied to the object class, property, or representation taxa to more fully qualify the classification of the particular administered item. ISO/IEC 11179-2:2005 summarizes the basic attributes and model specified in ISO/IEC 11179-3:2003.
