Service-oriented Workflow Metamodel and System

For solving the problems appearing in the application of SOA to various types WFMS, such as WFMS which includes many human activities, a metamodel of Service-oriented workflow process, SOWF-MM, is proposed. In SOWF-MM, services are regarded as resource, a service is bound to a service role when an abstract workflow process model is instantiated, and services may be invoked by different way according to different activities types. Finally, a WFMS, SOWF-MS, is developed to supporting the execution of workflow process model which accords with the metamodel.
