定义一个框架，通过确定哪些实体需要被类型化，以及需要对已识别的类型说些什么，来描述ODP系统中感兴趣的类型。它提供了访问开放式分布式处理系统中使用的类型描述的标准方法，其中类型描述可以是这些开放式分布式处理系统中使用的各种具体语法和类型语言。它还为交互、绑定和交易目的的类型动态匹配提供了便利。

Defines a framework for describing types of interest in ODP systems by determining what entities need to be typed and what needs to be said about the identified types. It provides a standard method of accessing type descriptions used within open distributed processing systems, where the type descriptions can be in various concrete syntaxes and type languages used in these open distributed processing systems. It also facilitates the dynamic matching of types for interactions, binding and trading purposes.
