I've previously[1] talked about how stupid #WHOIS is, and while #RDAP is an improvement, it's still really just a bunch of information bits based on (regional) convention.

A human can usually quickly identify e.g., the owning legal entity from inspection of of the data, but good luck doing that programmatically.  It's infuriating.

 @79ea8cd4 Your criticism of RDAP is not clear to me. What could be sent by an information service but "bunch of information bits"? What is the regional convention you speak about? 
And about the difficulty to do it programmatically, sure, jCard is painful, but just finding the entry with ""roles": [ "registrant" ] is not to hard for a program.
