Sorry, Eric! We've known about this problem for a couple of weeks now and had the fix in place, but touching a production system requires motivation. I'll push to get the fix installed this week. In the meantime, here's a pointer to the file you're supposed to get when you ask for viaf.org/authorityScheme: http://dl.dropboxusercontent.com/u/68401641/authorityScheme.rdf Let us know if you have any problems with that!

I'm looking for an RDF file listing the classes and properties used by VIAF. VIAF can return RDF for specific entities, as in curl: curl -L -H "accept: application/rdf+xml" http://viaf.org/viaf/231063554/ Upon what RDF schema is this output based? The "header" of the output alludes to the following URI, but it returns an error: http://viaf.org/ontology/1.1/# - Eric Morgan
