JWPL is a language independent, database-driven, high performance Wikipedia API that provides structured access to information nuggets like redirects, categories, articles, and link structure. It contains a Mediawiki Markup parser that can be used to further analyze the contents of a Wikipedia page or standalone with other text, TimeMachine, which reconstructs a snapshot of Wikipedia from a specific date, or multiple snapshots from a time span, and RevisionMachine, which offers efficient access to the history of articles using a dedicated storage format which decreases storage space by 98%. This enables random access to the whole revision history without requiring several terabytes of storage for a single Wikipedia dump.
