If I want to transform any OSM (Open Street Map) location (point of interest/poi) to a group chat on Nostr (and use it as a feature most appropriate to Google Map reviews) - what NIP should I use, or how to design a suitable one?

Social networks, governments policies, failed startups, etc

I want to build the best social network based on maps. Kind of a messenger where you can chat with any destination. Imagine any address on the map can be a chat room. You can find any message anyone wrote in a location public chat, powered by AI (embeddings and vector search) I have no idea how to build it on Nostr yet.
