Here's the ontology in question: <a href="http://www.dayf.de/2004/owl/beer.owl">http://www.dayf.de/2004/owl/beer.owl</a><br>
<br>
The fact that it redefined "Hops" at line line 169 causes redland to
produce incorrect triples. Changing that like to rdf:about="#Hope"
allows redland to proceed as normal.<br>
<br>
These are the triples resulting from the original file<br>

Is there a way to get the parser to deal with this on its own? I can't
seem to think of a way that I could work around this. I know its a
problem with a file, but I know for a fact that other OWL parsers
(particularly Jena and OWLAPI) handle this gracefully. I'll poke around
some more, but your help would be greatly appreciated!<br>-- <br>- Boris
