Offline content generator

Wikimedia Foundation project[[::Category:WMF Projects]] Offline Content Generator (OCG) Creates offline formats from collections of mediawiki articles. Group: Features Start: 2014-01 End: 2017-09 Team members: Arlo Breault, Marc Ordinas i Llopis, Subramanya Sastry Lead: C. Scott Ananian

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.

See wikitech:OCG for more information.

The service was turned off on Wikimedia wikis in October 2017 (background: Reading/Web/PDF Functionality T150871).
