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.
