Cool! Seems simple. nostr:npub1arkn0xxxll4llgy9qxkrncn3vc4l69s0dz8ef3zadykcwe7ax3dqrrh43w is that how you do it in yondar?
Maybe NIP-32 using ISO-3166-2, with self reporting:
```
{
"kind": 40,
"tags": [
["L", "ISO-3166-2"],
["l", "IT-MI", "ISO-3166-2"]
],
"content": "{\"name\": \"Milan Cats\", \"about\": \"A test channel.\", \"picture\": \"https://placekitten.com/200/200\"}",
...
}
```

No, currently Yondar keeps key=value data in the GeoJSON properties, but my NIP is hoping to move that data into tags where crowdsourcing can take place: https://github.com/nostr-protocol/nips/pull/927
