So when you say “title” I assume you’re referring to half of a key-value pair.  A concept some large whois sources don’t have.

So there's no consensus between NICs for the information they should
have in whois and what search mechanisms they should provide? I guess
what you're saying is that whois is just a protocol definition and
nothing else?
