Combining RDF and OWL with SOAP for semantic web services
Yuxiao Zhao · 2004
This paper has two contributions: (1) we attempt to propose that a combination of RDF and OWL with SOAP is useful for building semantic Web services (SWS); (2) we show how to combine them technically. A SOAP Envelope comprises Header (control data) and Body (transaction data). They are defined in XML schema syntactically not semantically, resulting in inflexibility for Web services invocation. RDF and OWL introduce ontology-based semantics into SOAP. We provide four-level SWS: three-level combinations plus a base level for easy comparison. SWS at Level 0 (Internal Translation) can process multiple data formats by internally translating one format in SOAP into others.
