[protege-discussion] Protege 3.4 OWL to RDF error

[Tania Tudorache]

I'm not sure why you get the exception.

You should try either: File -> Export -> OWL  (with native and without 
native writer).

Or, you can choose, File -> Convert Project to Format -> RDF Files 

(not OWL/RDF File). This will generate two files: rdf and rdfs. If you 
only want one file, you can copy the content of one into the other.
