From DAML-S processes to BPEL4WS

Abstract

BPEL4WS is a process modeling language for composing Web services. On the other hand, DAML-S is an ontology for defining Semantic Web services that includes a process model. We present a one-way mapping from the DAML-S process model to BPEL4WS, focusing on their common aspect: providing a specification of a service's interaction protocol. The mapping clarifies their relation to each other, and enables DAML-S described services to be used by Web services requestors that are not semantically-enabled. A prototype translator was created, and examples are provided.
