Brilliant, we should set up a page with a list of SPARQL endpoits for
Wikidata! For production usage, it is great to have a variety to chose from.
==WARNING==
The RDF format is currently in flux. The purpose of the Chilean endpoint
http://milenio.dcc.uchile.cl/sparql is to gather feedback that helps us
how to possibly the RDF structure for greater utility/simplicity. There
will be several updates to the format in the net few weeks. Please help
us to find out what is needed by also testing at
http://milenio.dcc.uchile.cl/sparql. We gather query logs and are happy
to share them. This said, please also tell us if other endpoints work
better/differently/worse for you. Any feedback is welcome.
Cheers,
Markus

Hi everyone,
I'd just like to announce another experimental Wikidata SPARQL endpoint
[1], kindly provided by the folks at SpazioDati [2].
It contains both the simplified and the complete dumps, as per [3].
Each dump file is stored under a different named graph.
We are collecting the query logs, and will share the most frequent queries.
Cheers!

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 .
