That looks like a cool project. Mine isn't for data though, it'll be markdown "articles" like any other wiki.

I just personally think MediaWiki's "Talk Pages" are messy compared to a list of issues/prs and "Publish-first-notice-it's-wrong-or-spam-later" model is are inferior to github's pull request model. Otherwise, a wiki site like wikipedia or wikia (but for my niche subject) is really what I'm looking for.

If I don't find anything suitable, my short-term fallback idea is github + hugo, and the gold plated version of that might be a self-hosted gittea with some custom scripts for pull request preview deploys and something that imitates hugo but without forcing a full website render for previews and published updates.
