+Wikidata is a repository of structured data about all kinds of knowledge in the
+world. Since 2012, it has grown to be a gigantic knowledge base that can be
+edited by everyone and used freely to answer all your questions. We will talk
+about how Wikidata is structured, how to query it with SPARQL, and what kind of
+applications people have already built with it. We will also introduce you to
+Wikibase, the MediaWiki extension that powers Wikidata and lets you create your
+own instance of a Linked Open Data knowledge base.
