多部分标准ISO/IEC 19763的主要目的是为互操作性指定一个元模型框架。ISO/IEC 19763-7:2015规定了用于注册服务模型的元模型，通过重用服务促进互操作性。 ISO/IEC 19763-7:2015仅适用于其功能由某些web服务描述语言描述的web服务（此类语言的示例见附录A）。图1显示了ISO/IEC 19763-7:2015的范围。

The primary purpose of the multipart standard ISO/IEC 19763 is to specify a metamodel framework for interoperability. ISO/IEC 19763-7:2015 specifies a metamodel for registering models of services, facilitating interoperability through the reuse of services. ISO/IEC 19763-7:2015 is only applicable to web services whose capabilities are described by some web service description language (see Annex A for examples of such languages). Figure 1 shows the scope of ISO/IEC 19763？7:2015.
