description: >-
  Wikidata is a free, collaborative, multilingual knowledge graph hosted by the Wikimedia
  Foundation. It provides structured linked data for Wikipedia and other Wikimedia projects,
  as well as a public platform for anyone to read and edit. Wikidata exposes several APIs
  including a Wikibase REST API for entity read/write operations, the MediaWiki Action API
  for batch entity retrieval and editing, a SPARQL endpoint for complex graph queries,
  Linked Data URIs for individual entity access in multiple RDF formats, a real-time
  Server-Sent Events stream for change monitoring, and full database dumps for bulk
  data processing.
