9.1. CBOR Web Token (CWT) Claims Registry

IANA has created the "CBOR Web Token (CWT) Claims" registry [IANA.CWT.Claims].

Registration requests are evaluated using the criteria described in the Claim Key instructions in the registration template below after a three-week review period on the [email protected] mailing list, on the advice of one or more Designated Experts [RFC8126]. However, to allow for the allocation of values prior to publication, the Designated Experts may approve registration once they are satisfied that such a specification will be published.

Registration requests sent to the mailing list for review should use an appropriate subject (e.g., "Request to register claim: example"). Registration requests that are undetermined for a period longer than 21 days can be brought to the IESG's attention (using the [email protected] mailing list) for resolution.

Criteria that should be applied by the Designated Experts includes determining whether the proposed registration duplicates existing functionality, whether it is likely to be of general applicability or whether it is useful only for a single application, and whether the registration description is clear. Registrations for the limited set of values between -256 and 255 and strings of length 1 are to be restricted to claims with general applicability.

IANA must only accept registry updates from the Designated Experts and should direct all requests for registration to the review mailing list.

It is suggested that multiple Designated Experts be appointed who are able to represent the perspectives of different applications using this specification in order to enable broadly informed review of registration decisions. In cases where a registration decision could be perceived as creating a conflict of interest for a particular Expert, that Expert should defer to the judgment of the other Experts.

Since a high degree of overlap is expected between the contents of the "CBOR Web Token (CWT) Claims" registry and the "JSON Web Token Claims" registry, overlap in the corresponding pools of Designated Experts would be useful to help ensure that an appropriate level of coordination between the registries is maintained.
