本建议|国际标准: ? 介绍了ODP的概念和动机； ? 概述了开放分布式处理（RM-ODP）的参考模型和 解释其关键概念； ? 提供RM-ODP应用指南。 本建议|国际标准包括概述和详细解释，可在 阅读标准时的各种方式: a） 如果您打算只阅读本建议|国际标准，以获得对 ODP对贵组织的重要性，请关注第6条； b） 如果你打算研究整个RM-ODP，你也应该在继续之前阅读第6条 ITU-T Rec.X.902 | ISO/IEC 10746-2和ITU-T Rec.X.903 | ISO/IEC 10746-3； c） 当您阅读ITU-T Rec.X.902 | ISO/IEC 10746-2和ITU-T Rec.X.903 | ISO/IEC 10746-3时，您可以 我希望参考第7至10条，该条对这些条款所涉及的各种概念给出了支持性解释 共同文本定义； d） 当您完成ITU-T Rec.X.902 | ISO/IEC 10746-2和ITU-T Rec.X.903的一读时| ISO/IEC 10746-3，阅读讨论ODP系统中标准使用的第11条和第12条 并提供一些在系统规范中应用ODP概念的示例。

This Recommendation | International Standard: ? gives an introduction and motivation for ODP; ? provides an overview of the Reference Model of Open Distributed Processing (RM-ODP) and an explanation of its key concepts; ? gives guidance on the application of the RM-ODP. This Recommendation | International Standard covers both overview and detailed explanation, and can be consulted in various ways when reading the standards: a) if you intend to read only this Recommendation | International Standard, to gain a general understanding of the importance of ODP to your organization, concentrate on clause 6; b) if you intend to study the whole RM-ODP, you should also read clause 6 before moving on to ITU-T Rec. X.902 | ISO/IEC 10746-2 and ITU-T Rec. X.903 | ISO/IEC 10746-3; c) as you read ITU-T Rec. X.902 | ISO/IEC 10746-2 and ITU-T Rec. X.903 | ISO/IEC 10746-3 you may wish to consult clauses 7 to 10, which give supporting explanation for the various concepts that these common texts define; d) when you have completed a first reading of ITU-T Rec. X.902 | ISO/IEC 10746-2 and ITU-T Rec. X.903 | ISO/IEC 10746-3, read clauses 11 and 12 which discuss the use of standards in ODP system specifications, and provide some examples of applying the ODP concepts in the specification of systems.
