Universal Language Selector/Deployment/Planning

This is the provisional deployment plan for the MediaWiki extension UniversalLanguageSelector (ULS) to all wikis managed by the Wikimedia Foundation planned for May and June 2013. The Universal Language Selector is a tool that allows users to select a language and configure its support in an easy way. It replaces extensions Narayam and WebFonts.

Offered functionality

 * 1) User interface language selection for logged in users.
 * 2) Web fonts
 * 3) Input methods

A full description is at Extension:UniversalLanguageSelector.

Limitations

 * ULS is only supported in the following skins: Vector, Monobook, Modern.
 * On Wikimedia wikis, user interface language selection using the ULS is only available for logged in users. For anonymous users, web fonts and input methods are available.

Configuration
There are two possible configurations for ULS on a wiki, depending on its function.


 * 1) Projects with language versions (Wikipedia, Wikibooks, Wikiversity (except betawikiversity), Wiktionary, Wikiquote, Wikivoyage, Wikinews, Wikisource (except oldwikisource). For these wikis, the bulk of the wikis of Wikimedia, ULS will be visible as a cog icon in the menu area for interlanguage links. This configuration can be referred to by "ULS interlanguage" or "ULS cog icon".
 * 2) * Test environment: http://en.wikipedia.beta.wmflabs.org/wiki/Special:Version. Unfortunately beta labs has a caching issue. You may see  instead of "Languages" or no cog icon on some pages while not logged in.
 * 3) Projects without language versions, with or without multi-lingual content, and all other Wikimedia wikis, will have an icon for the ULS added in the personal tools at the top of the page. There are no separate test environments for this feature. It is in production on Meta-Wiki, Wikidata, MediaWiki.org, Wikimedia Belarus, Incubator wiki, Outreach wiki, Sources wiki, Wikimania wiki 2012 and 2013 . This configuration can be referred to by "ULS personal" or "ULS multi language".
 * 4) * Test environment: http://commons.wikimedia.beta.wmflabs.org/wiki/Special:Version. Unfortunately beta labs has a caching issue. You may see  instead of "Languages" or no cog icon on some pages while not logged in.
