Wikibase
Wikibase is a set of MediaWiki extensions for working with versioned semi-structured data in a central repository. It is based upon JSON instead of the unstructured data of wikitext normally used in MediaWiki. Its primary components are the Wikibase Repository, an extension for storing and managing data, and the Wikibase Client which allows for the retrieval and embedding of structured data from a Wikibase repository. It was developed for and is used by Wikidata, by Wikimedia Deutschland. (from: https://en.wikipedia.org/wiki/Wikibase)
