由于服务的分布与协作特性,有必要在服务合约库系统间进行协作.然而,目前的大多数服务合约库系统都遵循自己的服务合约标准和服务合约分类标准.针对这种状况,本文提出了一个用于对分布式服务合约库系统进行建模的元模型.首先,本文描述了一个大多数服务合约库系统所遵循的功能模型,然后基于此从服务合约库系统的结构和互连体系这两方面详细地阐述了这个元模型,并在UML2.0中进行了扩展,形成一个UML外廓.本文进一步地阐述了利用该外廓对青鸟分布式服务合约库系统所建立的模型.
Because of characteristics of distribution and collaboration of services, it is necessary to collaborate between different service contract library systems. However, most service contract library systems follow their own standards for the service contacts and the classifying of service contracts, etc. In order to solve the problems, this paper presents a meta-model for modeling distributed service contract library systems. The paper fLrSt describes a function model followed by most service contract library systems, and then presents the meta-model from views of the structure of service contract library systems and the connectivity of service contract library systems based on the function model. The meta-model is extended in UML, and a UML profile is formed. Further, The paper describes the Jade-Bird distributed service contract library model that is modeled with the profile.
