在这篇论文,一个模型基于有颜色的 Petri 网(CPN ) 提供语义支持因为万维网服务作文被建议,并且合成服务的可靠性和可维护性被改进。在模型的合成构造是顺序,同时发生的事件,选择,循环并且代替。万维网服务被 CPN 正式定义。关上的创作代数学被定义获得启用万维网服务的说明作文的一个框架。合成服务的可获得性,机密,和正直在模型的框架以内被分析基于的 CPN。
In this paper, a model based colored Petri net (CPN) to provide semantic support for web service composition is proposed, and the reliability and maintainability of composite services are improved. The composite constructs in the model are sequence, concurrent, choice, loop and replace. The web service is formally defined by a CPN. A closed composing algebra is defined to obtain a framework which enables declarative composition of web services. Availability, confidentiality, and integrity of composite service are analyzed within the framework of the model based CPN.
