As far as I understand the process to initiate further EPP work in the IETF

demonstrated, BOF, etc OR another option is to file an informational RFC.

I missed Patrick's presentation at the ccNSO tech day, but did read the draft that he circulated a while ago.

From my perspective, the main problem with how the implementations have evolved is a loss of interoperability. IIRC, in the case of CZNIC, complete schemas were defined to replace the standard domain and contact mappings, reducing EPP into not much more than a framing protocol. Not sure exactly the rationale for doing that, though I'm sure considerable thoughts have been put into it. It does mean that registrars could not easily reuse existing libraries or code written for one registries to talk to another though.

Its been said before, but I'll say it again, EPP is an Extensible protocol.
Given its flexibility, I have yet to hear an argument as to why existing
issues cannot be addressed using the extension system.

See above. Also, I believe there are some minor tweaks that could be done to the existing schema that would make less inherent assumptions about the registry data model (by making some fields optional). However, I don't any way to handle schema changes in a backwards compatible manner.

Working along the lines of defining new mapping encompassing common use cases would perhaps be worth pursuing and more productive than attempting to change the core protocol. Patrick's work would certainly come in handy in that case.

wil.

If a valid argument can be made, I am happy to support additional efforts on
the base protocol, as of yet, I have not seen one.

Best Regards,

Michael Young

Subject: [ietf-provreg] Presentation on EPP present and future

Hello,

I've done last monday in the ICANN ccNSO
tech day a presentation on my current view of EPP, based on the
extensions seen in the wild, and what could be future works on EPP
with some data on the 60+ extensions I've seen, and choices among EPP
"options" (host as attribute or contact, contact data, etc.)

You can find the presentation online here:
http://www.dotandco.com/services/software/Net-DRI/docs/netdri-future-epp-ica
nn-brussels-ccnso-techday-201006/index.html
or if you want just the text as PDF:

nn-brussels-ccnso-techday-201006/netdri-future-epp-icann-brussels-ccnso-tech
day-201006.pdf

While the attendance was high, there has not been any real feedback
at that time on the relevance on working again on EPP or even, as
stated in my presentation, to try at least to make people (from
registries, registrars, and outside developers such as myself) to
collaborate together, starting with extensions documentation and
public announcements.

Hope that helps.
