标准摘要
[中文适用范围]： CDIF 系列国际标准主要设计用于描述建模工具之间传输信息的机制。 当导入和导出工具的作者除了遵守 CDIF 的协议之外没有任何共同点时，它有助于成功转移。 为传输格式定义的语言也可用作从存储库导入/导出的通用语言。 为 CASE 定义的 CDIF 语义元模型也适用于作为存储库中使用的标准定义的基础。 构成 CDIF 标准完整系列的国际标准记录在 ISO/IEC 15474-1:2002，信息技术 — CDIF 框架 — 第 1 部分：概述中。 这些标准涵盖了总体框架、传输格式和CDIF语义元模型。 该国际标准定义了 CDIF 语义元模型的数据定义主题区域。 该主题区域包含用作其他主题区域标准的数据组件基础的元对象，以及适用于所有数据相关元对象的元关系和元属性。 [外文原描述]： ISO/IEC 15476-3:2006 explains the Data definitions subject area of the CDIF semantic metamodel, that defines the primitive data types and the objects which are used for structured data. The CDIF semantic metamodel is used to ensure that the information transferred by tools communicating using CDIF is expressed with an agreed meaning. This subject area contains meta-objects that are used as the basis of the data components of other subject area standards, and also meta-relationships and meta-attributes that are applicable to all data-related meta-objects. ISO/IEC 15476-3:2006 is intended to be used by anyone wishing to understand and/or use CDIF. It provides a definition of a single subject area of the CDIF semantic metamodel. It is suitable for: Those evaluating CDIF;Those who wish to understand the principles and concepts of a CDIF transfer; andThose developing importers and exporters.
