We're getting there. Kinda.
It seems to be a matter of days before CoMaps adds support for displaying user reviews in their Android app, as the first user-oriented open source map app to do so. I'm pretty excited about that. The code just needs to be reviewed at this point.
The reviews will be sourced from Mangrove.reviews, who have been in the business of open data reviews for a while. It seems like a decent project, run by @mangroveReviews@mas.to, though their current website is very difficult to use. I don't really know how moderation works on the platform so I can't really claim to understand it, but it seems to be a pretty flexible standard for reviews attempting to be a bit of a one size fits all solution.
Currently the best way to write reviews to mangrove.reviews is using an app called MapComplete. It takes effort.
An alternative open review platform based on ATproto is cartes.app, but I don't think it's used by any map apps yet. The project website is however much more usable than Mangrove.
My personal preference would be for a federated review service using ActivityPub, but that's just a dream I'm having.
For now, keep an eye on @CoMaps@floss.social. Hopefully them implementing Mangrove support will motivate people to start writing reviews there.
