Meta model and modeling language for workflow supporting service collaboration
|
Abstract:
There are limitations in currently existing modeling language supporting web services, such as high complexity, poor interoperability and lack of effective support for service collaboration relationship. Process definition meta model of service-oriented workflow was presented on the basis of the analysis of service collaboration requirements, and the corresponding formal model was introduced. A model language for Service-oriented XML Process Definition Language (SoXPDL) supporting service collaboration was defined by extending XPDL.
