Hi Kingsley,

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.
Great, the more the merrier! I did not know about these so far :-) Anyway, we are not claiming an award for being the first (when we put up the RDF dumps, we did hope that there would be an endpoint sooner ...). The important point now is to get the community working with this to gather feedback to help us tweak the RDF dumps for maximal utility. The folks in Chile are helping us to gather first-hand experience in providing such a service (as you will know, the plan is to offer official SPARQL endpoints for Wikidata in the future).
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)
Yes, works like a charm. Impressive that you can do this with all the data in one store!
[2] http://wikidata.metaphacts.com/sparql -- another endpoint I discovered yesterday .
Interesting find. This one did not answer correctly to all the queries, but some worked quite well.
And of course there is the LDF endpoint provided by Cristian Consonni (http://wikidataldf.com/). However, this is a different technology and it cannot answer queries very fast.

#1 was actually loaded a long time ago :)
