Hi *,

In my opinion, in order for RDAP to be successful, those use cases will have to be taken into account. Regular users do use WHOIS to query for availability, or if a name is unavailable they want to know why, I know this first hand from feedback we received when we launched Uniregistry.

for instance:

```
$ whois -h whois.nic.link thisnameisavailable.link
The queried object does not exist: Domain thisnameisavailable.link is available for registration.

Last update of WHOIS database: 2016-12-07T23:41:41.710Z <<<

[…]

```

```
$ whois -h whois.nic.link iana.link
The queried object does not exist: See below for more information
registry reserved

Last update of WHOIS database: 2016-12-07T23:42:27.510Z <<<
[…]
```


```
$ whois -h whois.nic.link iana.foobarbaz
The queried object does not exist: See below for more information
tld not supported by this registry interface

Last update of WHOIS database: 2016-12-07T23:42:43.702Z <<<

```

```
$ whois -h whois.nic.link obispo.link
Domain Name: obispo.link
Domain ID: DO_d278b6e470d7fc1d3135e5261b65dc34-UR
WHOIS Server: whois.uniregistry.net

```


Those use cases need to be preserved in the new system, we must be able to signal different responses based on the object situation, and as a registry, people expect this to be authoritative and accurate.

It sounds like you’re attempting to morph RDDS into the SRS. RDDS is a lookup service and the SRS is an OLTP system. A lookup service either has the data or it doesn’t. Extra business logic associated with availability (variant blocking, relationship blocking, reserved domains, etc.) should be left to the appropriate channel which is the SRS and not RDDS.

    I will just point out that this is the _exact_ reason some of us
thought the bootstrap mechanism should have been SRV records in the
    DNS, because it would have neatly solved that exact problem.

I agree with this in principle, but given the way humans actually use the RDDS, there's going to need to be _some_ way to communicate this
    difference.  In particular, for policy reasons it's important to
understand "this domain isn't available because someone has it", "this domain isn't available because someone has something that prevents it
    being registered", and "this domain isn't available to anyone for
policy reasons." Consider people doing compliance checks, who maybe
    shouldn't have access to the SRS directly and who should only have
    access to the RDDS.  They still need to be able to see these
    distinctions.
