[regext] using subdomains in RDAP bootstrap

2024-04-08 Thread Dmitry Kohmanyuk
Hello everyone,

As a long-time lurker on regext@ and an infrequent participant in IETF 
meetings, I apologize if I missed something.  We have a practical issue with 
RDAP.

My registry, Hostmaster.UA have implemented RDAP for UA (URL: 
https://rdap.hostmaster.ua/, as included into IANA bootstrap.) Similarly to say 
UK we have multiple public suffixes where domains are registered, such as 
com.ua net.ua odesa.ua etc.

The trouble is, some of these domains are not managed by us;  let’s say that 
alice.ua would have rdap.alice.ua,  and bob.ua, rdap.bob.ua whereas com.ua 
would use IANA bootstrap element. Now, I want RDAP service to be as seamless as 
possible.

How can we implement this?  IANA JSON registry only has TLDs.  I can of course 
create my own bootstrap file but I cannot imagine practical way of informing 
RDAP clients of it’s existence.  I can use HTTP codes “moved permanently” when 
answering RDAP queries on our server.  (I can query the other server myself and 
serve the response; bad idea.)

Is there a most effective way to do it? Thanks!

As I (silently) said by raising my hand on Tuesday I am interested in this (.UA 
ccTLD).

This being said, the good thing about regexps is that there are so many 
varieties to choose from, so we have to be careful.

What is needed for this to happen?

which asks for CC=country-code but still uses full country name (USA) in 
examples.

my own opinion is that ISO code is better: less ambiguous (United States / USA 
/ US etc). the problem with that is some countries do not habe these codes 
(example: Kosovo.)

we also have some ISO 3166 codes which are not a country, for example EU, or 
*were* (like SU.)

For reference, our UA ccTLD service (https://ap.hostmaster.ua) returns country 
names, not codes,  so at least one exception exists.

another thing’s to consider: using country code instead of country name, in 
some rare cases, may be considered better by its residents if their country 
code refers to colonial name (touchy.)
