[regext] RDAP questions

[Brian Mountford <[e-mail]>]

I have a couple questions about RDAP RFC 7483.
RFC 7483 4.7. Port 43 WHOIS Server

For registries such as ourselves, is this supposed to be the registrar’s
server, or ours? I would have thought the registrar’s since WHOIS AWIP is
that way. But the registrar’s WHOIS is a URL, whereas this is explicitly
not so.
RFC 7483 5.1. The Entity Object Class

The RFC indicates that among the items of information we should return for
an entity is its role (admin, tech, billing, registrar, etc.). But contacts
don’t necessarily have a single role. The same contact could have more than
one role in more than one domain. In our database, the role tag is
associated with the mapping of the domain to the contact, not with the
contact itself. So it’s not clear how we can provide this information for
contacts found using a direct search. For contacts displayed as part of a
domain search, or for registrars, it’s not a problem.

Thanks.
