Wikimedia Hackathon 2024/MediaWiki Track

MediaWiki Track and why this is important!

As part of the Wikimedia Foundation's annual plan for FY23/24, the Wiki Experiences 3 (WE3): Knowledge Platform objective and key results (OKRs) were created.

The key result we're focusing on - for the 2024 Hackathon - is:

Increase by 20% the number of authors that have committed more than 5 patches across a specific set of MediaWiki repositories that are deployed to production.

What to do: a few project ideas / focus areas

CSS changes in MediaWiki core
Linting (extension / Parsoid)
Internationalization -> changes to the language file, or to the parameters
