Michele, A nit in your comment, the requirement applies to ³thin² registrations. BTW, a Registrar may optionally provide an RDAP service. Regards, Gustavo On 8/31/16, 04:34, "Michele Neylon - Blacknight" <michele@blacknight.com> wrote:
Sorry if I¹m coming late to the party .
This conversation makes it sound like registrars are expected to run RDAP services .. but since they¹d only be used for ³thin² registries they¹d only be used for a very limited time ..
Am I missing something?
Regards
Michele

Unfortunately, HTTP redirections are not an option in the case of the gTLD space, because Registries are contractually required to provide an RDDS response.
From an operational perspective, I think that HTTP redirections are also not an option in the case of the domain industry, because the prevalent business model has two parties (i.e. Registries and Registrars) keeping certain portions of the data elements. For example, the Registry is the authoritative source of information for the domain statuses.
Gustavo, if I'm understanding what you're saying correctly it would seem to be a description of a use case in which redirection would actually be a *good* operational practice. If a registry has some data elements and a registrar has other data elements I believe it's possible to retrieve both sets of elements if (for example) a registry receives a query and responds with an HTTP 300 (Multiple Choices) status code:
https://tools.ietf.org/html/rfc7231#section-6.4.1
The RDAP response data from the registry can be carried in the body of the redirecting response. The client follows the redirect (or URI reference(s) found in the payload) to the registrar, sends the registrar a query, gets a response, and both sets of data elements are retrieved.
