Thanks for the post. The knowledge sharing by the Data team & your open source efforts are amazing!
A fairly nice open source alternative going in the same direction is openKB: https://github.com/mrvautin/openKB
- unified search
- markdown text editor including process charting & formula capabilities
- user management
- API to post (pull metadata from database/ service & post to openKB)
It might be worth contributing in case you would want more features.
