Relay List Metadata
draft optional
Defines a replaceable event using kind:10002 to advertise relays where the user generally writes to and relays where the user generally reads mentions.
The event MUST include a list of r tags with relay URLs as value and an optional read or write marker. If the marker is omitted, the relay is both read and write.
{
"kind": 10002,
"tags": [
["r", "wss://alicerelay.example.com"],
["r", "wss://brando-relay.com"],
["r", "wss://expensive-relay.example2.com", "write"],
["r", "wss://nostr-relay.example.com", "read"]
],

}
When downloading events from a user, clients SHOULD use the write relays of that user.
When downloading events about a user, where the user was tagged (mentioned), clients SHOULD use the user's read relays.
When publishing an event, clients SHOULD:
- Send the event to the write relays of the author
- Send the event to all read relays of each tagged user
Size
Clients SHOULD guide users to keep kind:10002 lists small (2-4 relays of each category).
Discoverability
Clients SHOULD spread an author's kind:10002 event to as many relays as viable, paying attention to relays that, at any moment, serve naturally as well-known public indexers for these relay lists (where most other clients and users are connecting to in order to publish and fetch those).
