[gtld-tech] [eppext] RDAP server of the registry

Gustavo correctly notes some important things --ICANN has contractual
requirements that tell registries and registrars what data they MUST deliver
(currently via the WHOIS protocol), and ICANN is now working on how that
data should be delivered via RDAP.   Whatever document is created is going
to be binding on registries and registrars.  As per the 2013 RAA, once RDAP
spec is mature “ICANN reserves the right to specify alternative formats and
protocols, and upon such specification, the Registrar will implement such
alternative specification as soon as reasonably practicable.”  The new gTLD
registry agreements contain similar.

RDAP’s supposedly been designed to deliver what ICANN might require of its
registrars and registries.  If so, we are embarking on an exercise in
implementation in the gTLD world, with ICANN as the policy authority.  BCPs
for ccTLDs etc. might be nice, but seem like a distraction from the
immediate task at hand.

The implementation requirements should certainly be well-thought-out, should
receive input (and hopefully collegial buy-in) from the parties who will
have to make it work, and should be clearly documented.  As Gustavo says,
ICANN has process to deliver that.  Requiring “community consensus” about
the contents, as Scott suggested, is a different and higher standard from
what has been agreed to in the ICANN contracts.

All best,

IMHO, this group (EPPEXT) could define a BCP for RDAP implementers (e.g.
clients, DNRs, RIRs) of RDAP. This document could contain text like:

* if you have information about an object, but you know about of another
entity that may have extra information of the same object, you can use a
links members with a rel:related to link to the RDAP server of the other
entity Š (thin DNRs->Registrars, RIRs->NIRs->ISPs, etc)

* HTTPS SHOULD be used, and the RDAP service MUST use the best practices for
secure use of TLS as described in RFC7525 or its successors.

This group (EPPEXT) could define a BCP for DNRs (e.g. ccTLDs, gTLDs, etc).
This document could contain text like:

* if you support IDN registrations, you MUST ....

Maybe the RIRs are interested in defining a BCP for RIRs?

The gTLD profile is a document related to ICANN policies, and like the gTLD
Whois advisory and the technical provisions of the registry agreement or
RAA, should follow the ICANN process (e.g getting feedback from the ICANN
constituencies, public comments, etc).

At this moment, the gTLD profile contains technical implementation
provisions, because there are no documents that define those technical
provisions, but a future version of the gTLD profile could remove the
implementation provisions by referencing to the appropiate RFC(s).

The open issues of appendix A of the gTLD profile should be addressed by one
or several I-Ds, but I don¹t think they are only related to gTLDs. For
example, I know of at least a ccTLD that implements 5.

gTLD Registries want to have full requirements and an implementation plan
for all RDSS (i.e. whois, rdap) related activities, therefore the schedule
to have the gTLD profile ready looks tight.
