Thanks Stas and Markus.
I'm interested in computing various stats about Wikidata. For example, I want to
compute the degree of interlinking between Wikidata and external databases, per
entity type, per databases, etc. So I need a way to know which properties have
an external identifier as range, along with the name of the external database
they point to. For example P345 is an external identifier to IMDB ; P2639 is an
external identifier to Filmportal, etc.
The machine readable description of P2639 can be found at
<http://wikidata.org/entity/P2639.json> or, if you prefer,
<http://wikidata.org/entity/P2639.ttl>.
Similarly, the class "Film" is described at
<http://wikidata.org/entity/Q11424.json> resp
<http://wikidata.org/entity/Q11424.ttl>
Since these are regular "entities" (items or properties), they are themselves
described in terms of the wikibase data model and the wikidata vocabulary, not
in terms of RDFS/OWL.
