Thanks for your answer. Let's take an example to make sure I understood
I'm the registry for .example. The zone test.example is registered and
the registrar provided DS records.
If someone now uses my RDAP server and inquires test.example, I return
delegationSigned = true, because I know that DS records for text.example
exist. So far so clear.
For zoneSigned I see two possibilities:
1. I also return zoneSigned=true, because I assume that test.example is
2. I don't publish zoneSigned, because I don't know for sure, whether
the zone is signed.
In Case 1 delegationSigned and zoneSigned will always have the same
value, so there's no real benefit in publishing both.
As a consequence, as a registry I would say I always ignore zoneSigned
and don't publish it.
The only real use case for zoneSigned is, if I am a registrar and also
run the DNS service for my customer. Only then do I know for sure
whether the zone is signed or not.
