Wikibase
Wikibase is a system for storing and querying structured data that powers Wikidata.
Wikibase consists of two extensions:
- Wikibase Repository that allows a wiki to work as a repository for structured data.
- Wikibase Client that allows a wiki to access structured data from the repositories.
