    4141==== OWL ==== 
    4242While RDF just defines triples, [http://www.w3.org/TR/owl-features/ OWL] (Web Ontology Language) allows for defining classes of things, as opposed to opaque resources, for subjects (class), predicates (property) and objects (class). The previous examples that included things such as foaf:Person were using instances of classes from OWL ontologies. 
    43  * Simple example: an OWL ontology that describes a single class defined by duck-typing - anything belongs to CaffeineMetabolismParticipant if its value for isParticipantIn is the KEGG pathway for caffeine metabolism.

    4444==== SAWSDL ==== 
    4545Web 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).
