标准摘要
[中文适用范围]： ISO/IEC 11179 的这一部分规定了构建数据和元数据定义的要求和建议。 仅解决定义的语义方面；出于 ISO/IEC 11179 的目的，格式化定义的规范被认为是不必要的。 虽然特别适用于 ISO/IEC 11179-3 中指定的元数据注册表的内容，但 ISO/IEC 11179 的这一部分对于开发以下定义广泛有用：数据和元数据。 这些定义要求和建议涉及制定数据元素和其他类型的数据结构的定义，例如实体类型、实体、关系、属性、对象类型（或类）、对象、组合、代码条目、元数据项和引用的数据。 通过 XML 标签。 [外文原描述]： ISO/IEC 11179-4:2004 specifies requirements and recommendations for constructing definitions for data and metadata. Only semantic aspects of definitions are addressed; specifications for formatting the definitions are deemed unnecessary for the purposes of this standard. While especially applicable to the content of metadata registries as specified in ISO/IEC 11179-3, ISO/IEC 11179-4:2004 is useful broadly for developing definitions for data and metadata. These definitional requirements and recommendations pertain to formulating definitions for data elements and other types of data constructs such as entity types, entities, relationships, attributes, object types (or classes), objects, composites, code entries, metadata items, and the data referred to by XML tags.
