This is a port to XSB Prolog of the THEA owl parser, written by Vangelis Vassiliadis.
What does it do?
It is able to parse OWL/RDF graphs in OWL abstract syntax.
How does it run?
Just load owl_parser in XSB prolog, and you need to have already a set of rdf/3 terms in your prolog knowledge base. You can use the XSB RDF parser for it (lib_www). After that, it is just like in THEA!
