A Brief Introduction to Wikidata

Have you ever heard about Wikidata? If not, you might think of Wikipediafirst -- and that is not wrong. Wikidata is also a project of the Wikimedia Foundation. "Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia (…)." Loosely, you could describe Wikidata as Wikipedias database with over 46million data items (April 2018). And in line with Wikimedia's mission, everyone can add and edit data, and use it for free.
