Hajar Omrana, Ibrahim El Bitar, Fatima-Zahra Belouadha, Ounsa Roudiès · 2013
Web services Description has been recognized as an interesting paradigm that attracted significant attention from the research community. Currently, several WS description approaches have been presented to complete a detailed description with all the required aspects. The WSDL standard remains incomplete to provide a sufficiently rich description to service consumers. Thus, WSDL extensions as SAWSDL and WS-Policy have been proposed to offer a wider coverage of various WSs description aspects. Meanwhile, OWL-S and WSMO provide general representational frameworks for semantic Web Services. In this paper, we systematically compare WSMO, OWL-S and WSDL 2.0 enriched by SAWSDL and WS-Policy extentions, in the context of four aspects namely the functional, non-functional, technical and the data model aspects to better illustrate the strengths and the weaknesses of each of these approaches.
