ISO/IEC 19793:2015定义了统一建模语言（UML 2.4.1上层建筑规范，ISO/IEC 19505-2，用于根据开放分布式处理参考模型（RM-ODP，Rec.ITU-T X.901至X.904 | ISO/IEC 10746第1至4部分）定义的视点规范表达系统规范）和企业语言（Rec.ITU-T X.911 | ISO/IEC 15414）。它包括: a） 使用定义的UML概念和扩展（例如，结构规则、技术映射等），根据RM-ODP视点规范表达系统规范； b） 生成的RM-ODP视点规范之间的关系。 ISO/IEC 19793:2015适用于以下受众: -ODP建模人员希望使用UML符号以图形化和标准的方式表达他们的ODP规范； -想要使用RM-ODP概念和机制来构建其UML系统规范的UML建模者； -建模工具供应商，他们希望开发能够表达RM-ODP视点规范的基于UML的工具。

ISO/IEC 19793:2015 defines use of the unified modelling language (UML 2.4.1 superstructure specification, ISO/IEC 19505-2, for expressing system specifications in terms of the viewpoint specifications defined by the reference model of open distributed processing (RM-ODP, Rec. ITU-T X.901 to X.904 | ISO/IEC 10746 Parts 1 to 4) and the Enterprise Language (Rec. ITU-T X.911 | ISO/IEC 15414). It covers: a) the expression of a system specification in terms of RM-ODP viewpoint specifications using defined UML concepts and extensions (e.g., structuring rules, technology mappings, etc.); b) relationships between the resultant RM-ODP viewpoint specifications. ISO/IEC 19793:2015 is intended for the following audiences: - ODP modellers who want to use the UML notation for expressing their ODP specifications in a graphical and standard way; - UML modellers who want to use the RM-ODP concepts and mechanisms to structure their UML system specifications; - modelling tool suppliers, who wish to develop UML-based tools that are capable of expressing RM-ODP viewpoint specifications.
