Re: [Jwt-reg-review] [IANA #1352928] Request for Assignment (jwt, CTA-5009)

[Brian Campbell <[e-mail]>]

I honestly don't have the knowledge to evaluate the semantics of this
"geohash" claim but don't  in general object to its registration. It seems
okay to add.

I will note, however, that the registration request does not have the
"Specification Document(s):" part listed in the original registration
template <https://datatracker.ietf.org/doc/html/rfc7519#section-10.1.1>.
What does IANA plan to put in the corresponding "Reference" column of the
registry <https://www.iana.org/assignments/jwt/jwt.xhtml#claims>? I don't
think it can be omitted. The registry is supposed to "record the Claim Name
and a reference to the specification that defines it" according to the text
that establishes it
<https://datatracker.ietf.org/doc/html/rfc7519#section-10.1> (presumably so
that folks can find the corresponding specifications from the registry
entries). I suspect a similar question might arise for the CBOR and CWT
registration requests as well.

This sort of speaks to the Fast and Readable Geographical Hashing CTA-5009
specification being unfortunately rather cumbersome to access. It is
available free of charge, as mentioned, but requires a shopping cart and a
checkout process that requests some personal information. I've attached a
copy here for the convenience of other reviewers.
