| WikimediaApiPortal | #WikimediaApiPortal | WikimediaApiPortal is a skin for MediaWiki created by the Wikimedia Foundation Core Platform in 2020 as part of the API Gateway initiative. The skin is designed to mimic the look and feel of conventional developer portals by incorporating header and sidebar navigation elements and following the Wikimedia Design Style Guide. The skin uses the Bootstrap CSS framework, OOUI library, and Mustache templates. The skin was created for use with the Wikimedia API Portal, so some elements of the design such as the site logo and footer are specific to Wikimedia. | Unassigned | formerly Core Platform |

Upstream projects and libraries
Main page: Upstream projects
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.

References
- 1 2 3 4 5 6 7 8 Stewards are teams with professional responsibility over the development and overall health of the component. They commit to a base level of support such as high priority bug fixes and code reviews. A stewarding team must have one or more developers that can act as Maintainer, which means they can write changes but also have +2 access to the relevant Git repository to merge changes. In most cases, a steward is also the primary (and only) maintainer. For more information regarding stewardship, see Development policy/Code Stewardship.
- 1 2 3 4 5 Individual maintainers are developers that act as primary maintainer in lieu of a steward. This is usually the case for components that have no assigned steward (e.g. components that are volunteer-led), or where the steward has agreed to be a fallback.
- ↑ Consulted teams/people in this column can be consulted about changes as have useful expertise or experience. Typically +1, -1 or comment.
- 1 2 3 4 Consultants are developers/teams that have signalled an intent to answer questions or assist with problems, but should not be confused with maintainers. These may be former maintainers, or contributors in training.
- ↑ Informed when making significant changes in this area of code - teams/individuals here should be notified about changes (ideally via phabricator comment).
- 1 2 3 Maintainers have +2 access to the relevant Git repository and they regularly respond to bug reports and changeset review requests. Only maintainers can merge changes in Gerrit. Anyone may participate in Phabricator and in Gerrit to help investigate bugs or review code and gaining experience that way. If you're seeking to become an active maintainer, feel free to contact a steward or maintainer and share this desire by asking if they're willing and able to mentor and involve you proactively for a certain period of time.
