Dear all,
Thanks to the people at the Center of Semantic Web Research in Chile [1], we have a very first public SPARQL endpoint for Wikidata running. This is very preliminary, so do not rely on it in applications and expect things to fail, but you may still enjoy some things.
You have a SPARQL that provides access to Wikidata dumps loaded into an RDF compliant RDBMS (in this case a Virtuoso RDBMS instance). I emphasis "a" because "the first" isn't accurate.
There are other endpoints that provide access to Wikidata dumps:
[1] http://lod.openlinksw.com/sparql -- 61 Billion+ RDF triples culled from across the LOD Cloud (if you lookup Wikidata URIs that are objects of owl:sameAs relations you'll end up in Wikidata own Linked Data Space)
[2] http://wikidata.metaphacts.com/sparql -- another endpoint I discovered yesterday .
#1 was actually loaded a long time ago :)
