| 47 | 47 | Web services interfaces are described using web service description language ([http://www.w3.org/TR/wsdl WSDL]). In WSDL documents, semantic web services want to define the semantics of their inputs, outputs and services. This is done using [http://www.w3.org/2002/ws/sawsdl/ SAWSDL], which provides for the attributes modelReference (which defines the OWL class), liftingSchema (which links to an [http://www.w3.org/TR/xslt xslt] that lifts the [http://www.w3.org/XML/ xml] syntax into rdf) and loweringSchema (which links to an xslt that converts the rdf back to xml). |
