[regext] RDAP reverse search draft feedback

[Jasdip Singh <[e-mail]>]

Hello Mario, Scott,

Please find my feedback on https://datatracker.ietf.org/doc/draft-ietf-regext-rdap-reverse-search/  below:


  1.  Agree with the overall usefulness of this draft to cover the missing/needed search scenarios.
  2.  Not sure if we need to specifically mention in the draft but just noting that Regional Internet Registries (RIRs) also implement the domains search for their reverse DNS zones. :) Something to consider for the Introduction section?
  3.  Why introduce the keyword “reverse” in the search path? Is it to distinguish from the related reverse search scenarios (e.g. domains by nsIp) defined in 7843bis? In light of introducing a new extension for this draft, the “reverse” keyword may be redundant.
  4.  Instead of defining the generic reverse search path {resource-type}/reverse/{role}?{property}=<search pattern>, would it be better to take a specific search path, say domains versus nameservers versus entities, and define the new query parameters (that fill the current search gaps) for each of them section-by-section? Please ignore this comment if the intent here is to pivot around the roles defined in the IANA RDAP JSON Values registry.
  5.  Knowing that it gets more complex but is it possible that folks may need to pass multiple query parameters for conjunctive criteria? If so, {resource-type}/reverse/{role}?{property}=<search pattern> may need to evolve to account for multiple query parameters.
  6.  Though not directly related with this draft, just an observation from 7483bis that there the IP Network and Autonomous System Number objects can be listed in an entity (an org) lookup response but not the Domain objects. Not sure if this was by design?
  7.  May be just me but found the abstract a bit verbose. Move some of it to the Introduction section?

Thanks,
Jasdip
