Is there an OWL or RDF or other machine readable version of rNews?

The machine readable version of rNews is in the works. As soon as we're done shaking out the bugs we'll post it to this site, hopefully in the next day or two.

We now have a machine-readable version of the rNews specification at: http://dev.iptc.org/files/rNews/rnews.owl
Please note that this is a very rough draft and that we welcome all feedback on this document and will update and revise accordingly.

According to Michael, http://dev.iptc.org/files/rNews/rnews.owl does not load into Protégé 4.1.

The content-type of the ontology served is wrong (currently set to text/plain)
curl -I http://dev.iptc.org/files/rNews/rnews.owl
HTTP/1.1 200 OK

What content-type should we be sending?
Posted at 10:14 AM on April 8, 2011
- Per the RDF specification:
- Per the OWL specification:
The Web Ontology Working Group has not requested a separate MIME type for OWL documents. Instead, we recommend to use the MIME type requested by the RDF Core Working Group, namely
application/rdf+xml, or alternatively the XML MIME type
As file extension, we recommend to use either
If the ontology was using the N3 syntaxt, then I would have recommended the n3 mime type but this is not the case here.

what about the ontology at this URL: http://dev.iptc.org/rnewsowl - should have the correct MIME type.
I have to say that we have limited possibilities for tweaking the server of this site, this is a wiki system of a service provider.

Yes, http://dev.iptc.org/rnewsowl is served with application/rdf+xml so this is good!
However, my browsers (firefox and opera) tell me that http://dev.iptc.org/rnewsowl is invalid XML. Syntax error on line 4, character 19 per http://www.w3.org/TR/REC-xml/#NT-doctypedecl

Raphael and everyone,
the XML errors should be fixed. http://dev.iptc.org/rnewsowl now opens without issues in Protégé for me.

Is there an RDF version of the vocabulary now? What is the correct namespace to use for rNews?

I'm afraid the ontology is not available anymore...
