# DIDn't: did:un = KERI => DID

A Google Slides deck by Charles Cunningham of Jolocom, linked on keri.one as "DID Method Discussion for KERI", proposing a DID method (did:un) that transforms KERI identifier state into DID document contents. It explains KERI prefixes and derivation codes, which parts of key state map usefully to DID documents (keys, delegators and delegates) and which do not (thresholds, witnesses), and how delegation might be expressed with "controller" and "alsoKnownAs". For DID method designers.

Labels: reading level Implementer; evidence informative (an author's paper, deck, tutorial or post explaining the suite).
