Developers/Maintainers[edit]

This is a list of developers who know the most about, and maintain, MediaWiki core, key extensions, and Wikimedia servers.

To be listed as a maintainer a person has to have +2 access to the relevant Git repository and regularly respond to bug reports and changeset review requests.

If you are a maintainer, please consider using configuring Gerrit to send you an email for new patchsets in a repository. Alternatively you can add yourself to the Gerrit Reviewer Bot which will automatically add you as a review to each new patchset.

Anyone can list themselves as in training to maintain something, signaling that they want to learn more and achieve maintainership within the next year.

Code Stewards[edit]

Code Stewards are ultimately responsible for the development policies, support, and overall health of the code in question. As MediaWiki continues to grow and become further depended on by millions of users, it has become increasingly important that the code-base remains healthy while also enabling the continue evolution of its capabilities. Code Stewards enable this by committing to a base level of support such as bug fixes and code reviews. For more information regarding stewardship, please see Development policy/Code Stewardship.

Upstream projects and libraries[edit]

There are many upstream projects on which MediaWiki, extensions, and/or Wikimedia depend. Some of them were "invented here", as stand-along libraries, or split out as part of the Library infrastructure for MediaWiki project. Some of them are widely-used third party tools to which community members provide improvements or support. Others are merely used with gratitude.

Key extensions[edit]

Mostly extensions used by over ~400 standalone wikis.

Some of the areas below don't have their own Phabricator project, or have a project with a different name.
Component Description Maintainers In training
AdminLinks Defines a special page, "AdminLinks", meant to serve as a "control panel" for administrators; and adds a link to this page to their "user links"   Yaron Koren?
AntiBot Archived - Unmaintained   See extension page
CSS A parser-function for adding CSS files, article or inline rules to article   See extension page
ConfirmAccount disables direct account creation and requires the approval of new accounts by a bureaucrat   Nobody; formerly Aaron Schulz
CustomSidebar easy way to customize the sidebar on a per-page basis   See extension page
DataValues A small but fundamental building block for Wikibase.   WMDE Engineering
DeleteBatch Allows you to delete a batch of pages, either through the form or by uploading a text file containing the page-names   See extension page
EmbedVideo Adds a parser function for embedding video clips from popular video sharing services   See extension page
Google Analytics Integration Automatically inserts Google Universal Analytics (and/or other web analytics) tracking code at the bottom of MediaWiki pages   See extension page
Header Tabs Displays top-level headers as JavaScript-based tabs   See extension page
HTML Tags Defines a tag that allows for placing HTML tags on the page out of a set of allowed tags and attributes pre-specified by the administrator   See extension page

MsUpload Allows to upload multiple files via the editor including drag & drop   See extension page
Page Forms allows users to create forms for creating and editing pages that use infobox-style templates. Forms are defined within wiki pages, written in a custom markup language, and are parsed on-the-fly when a form is displayed   SMW folks, see SourceForge and GitHub
Replace Text Provides a form to let administrators do string replacements on the entire wiki, for both page contents and page titles   Yaron Koren?
Semantic MediaWiki Allows users to add structured data to wiki pages through simple wikitext markup that turns links to other pages and data values in a page into meaningful properties   SMW folks, see SourceForge and GitHub
Semantic Result Formats Adds further formats to render inline query results   SMW folks, see SourceForge and GitHub
Validator Provides generic parameter handling support to other extensions   SMW folks, see SourceForge and GitHub
Variables Introduces parser functions for dealing with page-scoped variables   MGChecker
VideoFlash Note: Please consider using the EmbedVideo Extension instead of this   See extension page
Widgets Allows adding free-type widgets to the wiki by editing pages in Widget namespace   See extension page
