RFC 8982 may or may not provide the model, but we will need a document in
either case. If the WG adopts this document, it can be developed with the input
and guidance of the WG.
[SAH] We already have a document in 8982. I'd like to understand if this draft 
solves a problem that isn't solved by 8982.
RFC 8982 only applies to search queries. That's clunky but presumably we don't 
care too much about that.

[ML] Its logical field of application is the RDAP search because it aims to limit the amount of information returned, which in a search response could be remarkable. But it can also be applied to RDAP lookups.

Honestly, it seems to me that parsing the content of a link header is more complex than getting the same information from a JSON structure, and since the payload of a search response is manageable, I wonder what the real benefit is.

It may be that all this document needs to do is standardize the value of the 
"fieldSet" parameter. Unless clients and servers agree on that, there can be no 
interoperability.

[ML] Don't see the complexity gap between agreeing on the value of the fieldSet parameter and agreeing on an extension identifier.

What makes a difference IMO is that an extension identifier is registered while the fieldSet parameter value isn't.

But RFC8982 can be updated to create a new IANA registry.


Best,

Mario
