Consider adjustment to TXT RData format

[mistermoe]

context: I'm in the middle of implementing did:dht in dart.

Is there any rationale behind _did.TLD storing all the relationships? parsing a TXT record that into a DID Document could be O(n) if each _kN_did. had a rel (relationships) property e.g. rel=auth,asm vs. having to look up the relationships in the root entry.

your point is correct. the design was chosen because I saw the biggest risk to the TXT size limit of being a key + a key ID. this is why there's guidance on suggested KIDs.

having longer TXT records is possible, but awkward, and I did not want to risk dealing with variations in tooling (still may have to). so - anything to reduce the size of a single record is 👍

that and I believe it's worth it to separate out relationships from key definitions, as is done in DID core itself (see verification methods opposed to verification relationships.

marking this as pending close
