Wikidata, a centralized structured data repository for facts and Wikimedia’s first big new project in the last 7 years, is now feeding the foundation’s main project, Wikipedia. The Wikidata project was kicked off around a year ago by the German chapter of Wikimedia, which is still steering its gradual development. For Wikipedia, the advantage is simple and powerful – if there’s a central, machine-readable source for facts, such as the population of a city, then any update to that data can be instantly reflected across all the articles in which the facts are included.
