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.
WikiPL provides a Python programming environment hosted in a MediaWiki server. Each article in the wiki contains either a Python function or a class named as the article's title. Moreover, the article can contain the source code, documentation, unit tests, development edition, permissions, and form elements for the parameters of the function. Users can view the documentation or edit and execute the source code. Execution can happen either on the local computer, on a remote server, or in the browser (through Pyjamas). Code in one article can be invoked by another article through regular function calls, without any changes to the syntax of the Python language. It also offers a package that imports article code into a local Python namespace for offline development.
