Composing Data-Providing Web Services
Claude Bernard · 2009
more than ever, modern enterprises are using Web services for data sharing within and across the ent erprise's boundaries. We call this kind of Web service as Dat a Providing Web services. In this paper, we present our approac h to automatically compose primitive data providing Web services for the purpose of creating data integration applicatio ns. Our approach exploits existing mature works done in dat a integration systems. Specifically, data providing services are modeled as RDF Parameterized Views over mediated ontologies. Then, an RDF oriented query rewriting algorithm is used to compo se services for answering received queries. The composition is then optimized and deployed as a new Web service accessible on top of the Web.
