Adapting P2P based decentralised workflow system SwinDeW-S with Web service profile support

SwinDeW, a novel peer-to-peer based decentralised workflow, has been upgraded to SwinDeW-S, which supports Web service deployments and enactments to enhance system openness. To specify business process semantics, descriptions of input, output, precondition and effects, traditional workflow definition languages, such as extended XPDL, which was used in SwinDeW, have become insufficient. Even new service-oriented business process languages, such as BPEL4WS, are unable to support the full description of service profile either. In this paper, we propose a new framework based on OWLS, a semantic Web ontology language that leverages service discovery, invocation and coordination more effectively.
