I apologize for the late response.  My vote would also be for option A.

Hi all,

I vote for option A, I think we can trust this WG to thoroughly interrogate any 
actual proposed use of bare identifiers to ensure that it's sensible.

 was discussed.  Currently there is one technical issue that has been under 
discussion on the mailing list for some time.  It was agreed during the meeting 
that the Chairs would seek to bring the discussion to a close by asking the 
open question on the mailing list.

The Chairs need your response.  We would most like to hear from folks who have 
not had much to say up to this point.

The question is what should the status of bare identifiers be in the “RDAP 
Extensions” draft?

Three possible answers have emerged.  The Chairs are opening a poll by 
presenting the three choices and asking folks to indicate the option they would 
most prefer to support.

Please note - this is not a discussion.  If you have a clarifying question you 
may ask and the Chairs will respond.  The Chairs are asking you to indicate 
which option you would most prefer to support.

The three options are as follows.

A. Always disallow them - Bare identifiers can cause confusion because they do 
not define a structured namespace.  The bare identifiers that already exist in 
the RDAP Extensions Registry would be permitted to remain as specified; new 
bare identifiers would not be allowed.

B. Always allow them - They already exist in the RDAP Extensions Registry and 
thus we know that they can work.  The IANA processes ensure there are no 
duplicate identifiers.

C. Only allow them if it is REQUIRED to solve the problem being considered - 
This option is a compromise that would require that guidance exist in order to 
evaluate whether or not the bare identifier is the only solution.

Some additional background information you may find helpful as you consider 
which option you would most prefer to support can be found in the following IAB 
guidance:

Also note that given there are already some bare identifiers defined in the 
IANA RDAP Extension Registry, all existing extensions will remain as currently 
specified.  The response selected here only applies to new extensions.

This poll will close on Wednesday, 1200 UTC, 27 August 2025.  Please select an 
option and indicate your choice on the list by replying to this message.

Recall from the meeting that the Chairs proposed that option 1 was the best 
course of action.

Thank you for your prompt attention,

Jorge, Antoin, and Jim
