More about Wikibase


Wikibase is an extension to MediaWiki, and relies on MediaWiki's features to provide all the functionality of a wiki – but for structured data.

This includes:

  • functionality to create and manage a knowledge base, including user-defined properties
  • mechanisms to access the knowledge base from other wikis and to update them on changes
  • a rich JavaScript-based UI
  • a data model that takes knowledge diversity and multilingual usage seriously
  • exports of the data in a number of formats like JSON, RDF/XML, N3, and YAML

On top of that, Wikibase adds:

  • full histories of all previous versions of the knowledge base, including by whom the change was made
  • a web-based interface with a number of features for wiki gardening, user security and identity, etc.
  • a platform known to be scalable for millions of readers and tens of thousands of editors
  • world-class internationalization and localization into more than 200 languages
