dlpconvert "dlpconvert is able to convert ontologies, that are within the dlp-fragment, from one syntax - namely the OWL XML Presentation Syntax - into another, here Datalog. Thus you can just take your ontology, convert it and then use the result as your program in your Prolog-engine. Isn't that cool?"
rdf2owlxml "Another KAON2 based tool just got finished, a converter to turn RDF/XML-serialisation of an OWL-ontology into an OWL/XML Presentation Syntax document. And it even works with the Wine-ontology."
