Actually, its a little bit more involved. The thinking here was moreso about location than not. If memory serves, the term 'authoritative' in context of the EWG's RDS really means the one and only place from whence reliable domain name data may be *accessed*. There is a presumption that there would be multiple sources for the data in that RDDS repository. FWIW, it is accepted that the upstream collection/collector maintains fealty to process; know your customer, data accuracy etc. etc. all rolled in. But the repository itself - the storage place - imprints 'authoritative' on the data resident there. -Carlton ============================== *Carlton A Samuels* *Mobile: 876-818-1799Strategy, Planning, Governance, Assessment & Turnaround* ============================= On Wed, Apr 5, 2017 at 10:41 AM, Greg Aaron <gca@icginc.com> wrote:
There are two different definitions of “authoritative” being used here. One is “where does the data come from,” i.e. what is the original source. Stephanie and Scott are using this first definition. The second definition is “what is the data of record, which should be relied upon.” I am using that second definition. I think the first concept is important to understand, but it cannot be used as the standard for a variety of legal, technical, and practical reasons. The history at ICANN, and recent policy-making, has been toward relying on thick registry data as the data of record, to be relied upon. My view was used by both the EWG and the Thick WHOIS PDP.
Stephanie, I think you’re wrong about what the EWG said. It did not use your definition, it used mine. The EWG said: “Requestors must be able to obtain authoritative data from the RDS in real-time when needed.” And the EWG said: “the RDS is the authoritative data source and provides authoritative access.” The EWG did not recommend that people be able to obtain certain kinds of data directly from registrars via RDS. Instead, the EWG said that RDS was to provide data from (thick) registries. The data in the registries is authoritative, and the RDS is the authoritative way to get that data held in the registries.
The Thick WHOIS PDP WG recently looked at the issue of authoritativeness, and our WG should consider it carefully. That PDP WG used my definition, not Scott’s. That PDP WG said that a thick registry is the authoritative repository of all data currently displayed in WHOIS. Quote below, with my notes in square brackets:
“Here is the working definition used by the WG while analysing this issue: ‘Authoritative, with respect to provision of Whois services, shall be interpreted as to signify the single database within a hierarchical database structure holding the data that is assumed to be the final authority regarding the question of which record shall be considered accurate and reliable in case of conflicting records; administered by a single administrative (agent) and consisting of data provided by the registrants of record through their registrars.’ A proposed shorter version is ‘the data set to be relied upon in case of doubt’. [In other words, the REGISTRY is the ultimate authority, not registrars.]
Authoritativeness in a Thin Whois Environment
Since the registrar alone holds most Whois data, its data is necessarily authoritative as to those data elements (e.g., name of registrant). For that data held by both registrar and registry (e.g., name of
registrar), it appears that registry data is generally treated as authoritative, but the WG is not aware of any official ICANN policy statement on this. The WG observes that in the case of the Uniform Dispute Resolution Policy (UDRP), UDRP Providers treat the registrar Whois information as authoritative, which may be the result of the UDRP having been adopted prior to the emergence of thick gTLD registries.
Authoritativeness in a Thick Whois Environment
Most comments that addressed this question stated that registry data is considered authoritative in the thick environment. Only one stated that the registrar data was authoritative. Again, the WG is
not aware of any official ICANN policy statement on this question. The WG notes that the registrar remains responsible for the accuracy of the data under either the thick or thin model, as the relationship with the registrant remains with the registrar. ..*the WG assumes that any data collected by the registrar becomes authoritative only after it is incorporated in the registry database*.” [emphasis added]
If anyone wants the registrars to remain the source of record for any data available throrugh an RDS, then:
1. That will sink the entire purpose of the thick registry effort, 2. It will make solving domain disputes harder than they are now, and 3. Registrars should be contractually required to serve RDS indefinitely. That’s contrary to the thick policy, a goal of which was to get registrars out of the business of serving their own WHOIS (or RDAP, or whatever).
All of which would be completely unnecessary and wasteful.
All best,

P.S.: Scott is using a corner case to support his argument. In 99.999% of cases, registrars do not ”push expiration dates to registries”. Registrars send in EPP Create commands and indicate a registration term in years. The registry time-stamps the create and expiration date based on the time the Create command is received. The registrar does not hold those dates authoritatively – the registry does. The only exception I know of is Verisign’s obscure “ConsoliDate” product, which is available in .COM and .NET and is used infrequently by a small number of corporata cleints to add days to expiration dates. In any case, the Create date in a registry may not correspond to the date/time the registrant entered into the contract with the registrar. What really matters is the date recorded in the registry.

It is not every day that I quote the EWG conclusions, as there are quite a few with which I disagree. In this case though, it does seem to me we discussed this exhaustively, and reached the conclusion that the registrars were the authoritative source. From a data protection perspective, this is consistent. I believe it would be the common view that the entity closest to the individual on the data map would be the authority on the data, not the entity further down the chain of control, and not the data controller (in this case ICANN). I realize I am mixing technical perspectives with legal perspectives here but I believe it is useful to flesh out how the matter is analyzed from each point of view.

Thanks, Mike. A few notes to contribute as people consider “authoritative”:
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).
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.
So the current situation seems to be pretty simple, and is on the path to getting even simpler:
1. If the registry is thick, the registry is authoritative for all data we see in WHOIS today.
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 **convenient** 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:
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.
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.

* 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.
