Not Discussed, but left in the notes just because...

DID Peer 2/3 – processing approach – is this the plan:
- Identifiers:
  - Long Identifier – as defined today, entire encoded DIDDoc in identifier
  - Short identifier is the first 22(?) characters of 64 character string sha256 of long identifier (or something else?)
- On receipt of a did:peer:2<identifier>, process as follows:
  - Detect length of identifier — short or long (assumption: long peer:did:2 will never be less than 23(?) bytes)
  - If short - resolve DID locally to get DIDDoc - on success, exit
  - If short and resolution failed — error, exit
  - If long
    - Convert long DID to short DID - resolve DID locally to get DIDDoc - on success, exit
  - If long and short DID resolution failed
    - Resolve long DID locally to get DIDDoc — on success, exit
  - if both short and long DID resolution fails
    - If on a “create DID” step (e.g. receiving DID Exchange “request” or “response” or DIDComm 2 new protocol step)
      - Extract DIDDoc from long DID, store short DID and DIDDoc, get DIDDoc — on success, exit
  - Otherwise — error
