Content Transform Team

The Content Transform team is responsible for maintaining the wikitext parsing products and Maps, among other things.

Mission Statement
[pending team review and discussion]

We deal with content formats, their transformations, and the associated engineering infrastructure.

History
Prior to May 2015, the erstwhile mediawiki core team was responsible for the mediawiki core PHP parser and the Parsoid team was responsible for Parsoid. Since May 2015, the erstwhile Parsoid team was rebranded as the Parsing team and the core PHP parser and Parsoid were brought under the purview of the Parsing team - this coincided with Tim Starling joining the group. Kunal joined the team in April 2016. As of April 2017, Tim and Kunal are now part of the Mediawiki Platform team. In August of 2021, the Parsing team welcomed members of Maps and Product Infrastructure and became the Content Transform Team.
