Technical Summary
The Registration Data Access Protocol (RDAP) does not include query
capabilities for finding the list of domains related to a set of
entities matching a given search pattern. Considering that an RDAP
entity can be associated with any defined object class and other
relationships between RDAP object classes exist, a reverse search can
be applied to other use cases besides the classic domain-entity
scenario. This document describes an RDAP extension that allows
servers to provide a reverse search feature based on the relationship
defined in RDAP between an object class for search and any related
object class. The reverse search based on the domain-entity
relationship is treated as a particular case.
