The name of that thing is supposed to be http://www.daml.org/2001/03/daml+oil#Class i.e. you're supposed to refer to the ontology using http://www.daml.org/2001/03/daml+oil NOT http://www.daml.org/2001/03/daml+oil.daml If you refer to the ontology that way, it works just fine: $ python2 ../../cwm.py --rdf http://www.daml.org/2001/03/daml+oil --n3 --base=absolutize: >daml+oil.n3 I checked in the results at: http://www.w3.org/2000/10/swap/test/dpo/daml+oil.n3 You can also get it from the converter that I think Jim is referring to N3<->RDF Conversion Service http://purl.org/swag/n3tordf So the results are available at: http://swag.semanticweb.org/n3tordf?uri=http%3A%2F%2Fwww.daml.org%2F2001%2F03%2Fdaml%2Boil&from=rdf By the way, for other reasons, I generated a version of daml+oil in "n-triples" format, which is an extremely simple dialect of N3 that the RDFCore WG is using for expected results of test cases: http://www.w3.org/2000/10/swap/test/dpo/dpo.nt one interesting thing about n-triples format is that I wrote a little perl ditty to convert it to KIF: http://www.w3.org/2000/10/swap/n-triples2kif.pl whence comes daml+oil converted to KFI: http://www.w3.org/2000/10/swap/test/dpo/dpo.kif dpo.kif would be more useful if we had a clean, machine-readable copy of the axiomatic semantics, separated out from the HTML etc. in http://www.daml.org/2001/03/axiomatic-semantics.html > Any takes - would be a nice document to add to our daml+oil release page Feel free to copy daml+oil.n3 and dpo.kif from w3.org to daml.org. But also... I'm pretty sure I've asked for the suffixes to be removed from the links in the daml+oil release page before; I got the impression the request was declined, but maybe it was just dropped, so let me make it again: Please remove the .daml and .html from the links in the index page http://www.daml.org/2001/03/daml+oil-index $Revision: 1.7 $ of $Date: 2001/03/28 06:26:55 $ and use the document titles, not filenames, as the link text; e.g. change | <LI>daml+oil-walkthru.html | - an annotated version of the example ontology to <li><a href="daml+oil-walkthru">Annotated DAML+OIL (March 2001) Ontology Markup</a> - an annotated version of the example ontology</li> (consider XHTML-izing while you're at it.) It's especially important that folks refer to the daml+oil stuff without the .daml; they get the wrong names otherwise. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
