With the prevalence of service-oriented architecture (SOA), web services have become the dominating technology to construct workflow systems. As a workflow is the composition of a series of interrelated web services which realize its activities, the interoperability of workflows can be treated as the composition of web services. To address it, a framework for interoperability of business process execution language (BPEL)-based workflows is presented, which can perform three phases, that is, transformation, conformance test and execution. The core components of the framework are proposed, especially how these components promote interoperability. In particular, dynamic binding and re-composition of workflows in terms of web service testing are presented. Besides, an example of business-to-business (B2B) collaboration is provided to illustrate how to perform composition and conformance test. 相似文献
