Contact from IPTC

An IPTC contact, User:Bquinnoz, just added this comment on the proposal page, but it's better discussed here:

Hi all, on behalf of IPTC, thanks very much for doing this work! We have RDF/XML versions of each NewsCode available at http://cv.iptc.org/newscodes/mediatopic/01000000?lang=en-GB&format=rdfxml, Turtle at http://cv.iptc.org/newscodes/mediatopic/01000000?lang=en-GB&format=rdfttl and JSON-LD at http://cv.iptc.org/newscodes/mediatopic/01000000?lang=en-GB&format=json. Can we include these in the RDF formatter for the property? If so, which one should we use (I guess RDF/XML?) and how do we account for languages? We have a "lang=x-all" option so should we use that?
