Towards a UML-Compliant Semantic Web Services Development

The coming of the semantic web and, in particular, the coming of the semantic web services (SWS) technology demands the inclusion of new components in the applications involving semantic web services. So, web development methodologies must be tailored to support the systematic development of such new components. In previous works we have presented an UML profile, which extends the SOD-M method for service oriented Web Information System development of the MIDAS model-driven framework, to address the development of Semantic Web Services using WSMO (Web Service Modeling Ontology). The UML profile allows for the modeling of the new elements required by WSMO Web Services. This paper focuses on study the possibility of improving the proposed UML profile, including the OCL (Object Constraints Language) for the representation of WSMO logical axioms, through three case studies. This way the developers’ whose knowledge does not extend beyond UML must be able to develop applications that use semantic web services.
