Offline Content Generator (OCG)
Creates offline formats from collections of mediawiki articles.
The Offline Content Generator service created offline formats, such as PDF and even plaintext, from collections of mediawiki articles; ePub and ZIM were planned for the future but never implemented. The Collection extension is used via Special:Book to create collections. The OCG service then invokes a /Bundler to spider the articles and fetch all images, stylesheets, etc required to render them. One of several /Backends are then invoked to convert the bundle into a PDF, ZIM file, or other appropriate output format.
