使用Web服务技术创建Web流程为我们提供了选择最适合我们当前需求的新服务的机会。这样做自动要求我们量化我们的选择标准。此外，还有一些具有挑战性的正确性和最佳性问题。我们在Meteor中提出了一个约束驱动的Web服务组合工具-S，它允许流程设计者根据业务和流程约束将Web服务绑定到抽象的流程，并生成可执行的流程。我们的方法是将大部分服务组合问题简化为约束满足问题。它使用多阶段方法进行约束分析。这项工作是作为Meteors框架的一部分完成的，该框架旨在支持语义Web流程的完整生命周期。
Creating Web processes using Web service technology gives us the opportunity for selecting new services, which best suit our need at the moment. Doing this automatically requires us to quantify our criteria for selection. In addition, there are challenging issues of correctness and optimality. We present a constraint driven Web service composition tool in METEOR-S, which allows the process designers to bind Web services to an abstract process, based on business and process constraints and generate an executable process. Our approach is to reduce much of the service composition problem to a constraint satisfaction problem. It uses a multiphase approach for constraint analysis. This work was done as part of the METEORS framework, which aims to support the complete lifecycle of semantic Web processes.
