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

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.
