标准摘要
[中文适用范围]: “类型”的概念是 ODP 系统的基础; ODP-RM的交互模型涉及强类型交互。 此建议|国际标准: ——通过确定需要对哪些实体进行分类以及需要对所识别的类型进行说明,定义了一个框架来描述 ODP 系统中感兴趣的类型。 这项工作的主要焦点是计算接口类型系统; ——在资料性附件中识别并描述足以描述上述识别类型的类型语言; ——在类型描述框架内提供通用类型存储库功能的企业、信息和计算规范,该功能可以专门用于选择特定的类型系统或类型符号。 类型存储库功能提供: · 类型描述的存储和检索; · 类型描述的管理; · 管理类型之间的关系,包括类型的匹配; · 类型的命名(以与 ODP 命名框架一致的方式); · 不同类型存储库的互操作和联合。 此建议|国际标准提供了访问开放分布式处理系统中使用的类型描述的标准方法,其中类型描述可以采用这些开放分布式处理系统中使用的各种具体语法和类型语言。 此建议|国际标准还促进了用于交互、绑定和交易目的的类型的动态匹配。 [外文原描述]: The concept of "type" is fundamental to ODP systems; the interaction model of ODP-RM involves strongly-typed interactions. This Recommendation | International Standard: ? 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. The primary focus of this work is the computational interface type system; ? identifies and characterizes type languages sufficient to describe the types identified above in an informative annex; ? provides enterprise, information, and computational specifications of a generic type repository function within the type description framework which can be specialized to select a specific type system or type notation. The type repository function provides: ? storage and retrieval of type descriptions; ? management of type descriptions; ? management of the relationship between types including matching of types; ? naming of types (in a manner consistent with ODP Naming Framework); ? interworking and federation of different type repositories. This Recommendation | International Standard 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. This Recommendation | International Standard also facilitates the dynamic matching of types for interactions, binding and trading purposes.
