A Survey on Services Composition Languages and Models
Antonio Bucchiarone, Stefania Gnesi · 2006
Composition of services has received much interest to support business-to-business (B2B) or enterprise applications integration. On one side, the business world has developed a number of XML-based standards to formalize the specification of Web services, their composition and execution. On the other side, the Semantic Web community focuses on reasoning about web resources by explicitly declaring their preconditions and effects with terms precisely defined in ontologies. So far, both approaches have been developed rather independently from each other. In this paper the major languages, namely BPEL4WS, BPML, WSCI, WS-CDL and DAML-S, are compared with reference to the requirements identified and finally the trend of Services composition is discussed.
