<p>The phrase "Registries exist to be authoritative repositories of
data" needs to be carved in stone over the entrance to these rds
discussion. <br>
</p>
<ul>
<li>Being simple minded, the tasks here are: "what data" and
"access under what terms". The complexities around those two
tasks are the core work of this rds-wg. <br>
</li>
<li>Issues of accuracy are (operationally) a Registrar-Registry
issue. They have to be addressed at that level. Registries
depend on Registrars for the primary data from domain name
registrants.</li>
<ul>
<li>ICANN and this wg may have views on how issues of accuracy
are addressed but that is a supplementary issue, and not the
core issue here.</li>
</ul>
</ul>
<br>
....my two cents here....as a registrant<br>

<b>Subject:</b> [EXTERNAL] Re: [gnso-rds-pdp-wg] Proposed
Definition/Background for Authoritative<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks, Mike. A few notes to contribute as
people consider “authoritative”:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Registries exist to be authoritative
repositories of data; that’s what they are designed to do.
(So, for example, two different people can’t register the same
domain name, or so a domain won’t resolve to the wrong
nameservers.) Domain registries are generally considered
authoritative for at least the thin data. (Domain, sponsoring
registrar, dates, statuses, nameservers.) The registry
creates or is the original recorder of record for most of
those fields (domain, sponsoring registrar, dates). And the
registry is authoritative for status and nameserver data,
using them to enable and control resolution, or to prevent
certain actions from taking place in the registry (such as
deletions, and registrar-to-registrar transfers).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Thick WHOIS PDP decided that all gTLD
registries should be thick. One reason was to ensure that
there won’t be any more disagreements (discrepancies) between
what the registrar says the data is and what the registry says
it is (and as seen via WHOIS or a successor system). Another
reason was to hold contact data in one place reliably, so it
could be served from one (authoritative) place; as a
consequence registrar port 43 service will eventually go
away. In other words, all registries should become
authoritative for all the data we see in WHOIS, if they are
not already. That was the desired policy and operational
outcome.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So the current situation seems to be pretty
simple, and is on the path to getting even simpler:
<o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoNormal" style="margin-left:0in;mso-list:l1
level1 lfo3">If the registry is thick, the registry is
authoritative for all data we see in WHOIS today.<o:p></o:p></li>
</ol>
<p class="MsoNormal"><b><i><span style="color:#1F497D"><o:p> </o:p></span></i></b></p>
<p class="MsoNormal"><span style="color:#1F497D">I can’t agree
with the conclusion that thick registries are authoritative
for all the data they possess. Being the last holder in a
chain of custody makes them a *<b>convenient</b>* source of
access to certain data elements, but they are not the
original, authoritative* (able to be trusted as being
accurate or true; reliable) source. An example:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">A registrar
creates an agreement with a registrant. That agreement has
an expiration date. The registrar pushes this expiration
date to the registry for publication in an RDDS. The
registry has no direct contact or relationship with the
registrant or the agreement between the registrant and the
registrar.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">In this and
similar indirect data collection situations, the registry is
just the last holder in the chain of custody. The registrar
is the original source of the data, and is thus a more
accurate and reliable source of information.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Scott<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:5.25pt"><span
style="color:#1F497D">* I think it’s very important for us
to agree on a definition of “authoritative”, and that
doesn’t mean that we get to make one up. I’ve included mine
(taken from the Oxford English dictionary) here.<o:p></o:p></span></p>
