Hi Estella, I believe that Owlim is trying to parse the .nt file as an n-triples file. From what I see your RDF is in a turtle format. The proper file extension for which is .ttl . Owlim uses the file's extension to determine which parser to use. I am applying a list of the most common RDF formats and their corresponding extensions:
RDF/XML - .rdf N-Triples - .nt Turtle - .ttl N3/Notation3 - .n3 You can read the specifications for those format at w3c's official site. RDF/XML - http://www.w3.org/TR/REC-rdf-syntax/ N-Triples - http://www.w3.org/TR/rdf-testcases/#ntriples Turtle - http://www.w3.org/TR/turtle/ N3/Notation3 - http://www.w3.org/DesignIssues/Notation3.html Hope this helps, Philip On Mar 5, 2013, at 9:12 AM, 金碧漪 <estella...@hotmail.com> wrote: > Hi Phil, > > As we all know, my domain-specific ontology needs to inherit the class Entity > from the PROTON System module.
