Hi Brian,
There is ongoing work in the ANIMA design team about the extension of the
discovery information for a registrar, to contain more information about
specific features of the registrar. We currently identified:
- the operational mode: registrar as responder (as in RFC 8995) or pledge as
responder (as in BRSKI-PRM)
- the enrollment protocol: EST as in RFC 8995) or CMP (as in BRSIK-AE) or
future adaptations
- the voucher format: CMS-signed JSON (as in RFC 8995) or JOSE-signed JSON (as
in JWS-Voucher used in BRSKI-PRM
The discussion is to define TXT key value pairs for DNS-SD, and use this
approach also for GRASP.
Yes, but you can map them in CBOR just as draft-eckert-anima-grasp-dnssd
already describes. (Think JSON but code CBOR.) My only real concern is how to
extend the objective for the AN_join_registrar. It seems lame to use plain text
when a JSON-style map would be much nicer for the programmer. My prototype code
for grasp-dnssd has to parse DNS records to change them into Python maps. But
once that's done, sending or receiving them as CBOR is trivial.
Best regards
Steffen

In hindsight, 8995 should have created an IANA registry for these.
