Does anyone have an idea why this would work:
  http://triplr.org/turtle/cbri.umn.edu/~trevor/wiki/Special:ExportRDF/An%2BInconvenient%2BTruth

But not this:
  http://triplr.org/turtle/ontoworld.org/wiki/Special:ExportRDF/An%2BInconvenient%2BTruth

This -
  http://cbri.umn.edu/~trevor/wiki/Special:ExportRDF/An%2BInconvenient%2BTruth

- is a plain text file (there is no wiki, it's just a URL), whereas this -
  http://ontoworld.org/wiki/Special:ExportRDF/An%2BInconvenient%2BTruth

- is delivered as application/xml. Same content so it should work the same. My only guess is that it has to do with the content type.

What do you guys think? Would http://ontoworld.org/wiki/Special:ExportRDF/An%2BInconvenient%2BTruth work if it was delivered as the rdf content type application/rdf+xml instead?
