Wikidata is a separate project, specifically for structured data in the form of semantic triples [0]. It's essentially the open-source version of Google's KnowledgeGraph; both sourced a lot of their initial data from Metaweb's Freebase [1], which Google acquired in 2010.
Many Wikipedia articles have infobox fields that pull their values from Wikidata (and are only editable through Wikidata).
