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.
