Re: [regext] New Version Notification for draft-ietf-regext-rdap-jscontact-04.txt

[Antoin Verschuren <[e-mail]>]

Hi All,

I’m glad that my bad phrasing at least got some action into this discussion.
I didn’t mean to say that we can’t have 2 standards, but we should at least have clarity on the status of this document.
Because the original document title was "jcard-deprecation <https://datatracker.ietf.org/doc/draft-loffredo-regext-rdap-jcard-deprecation/>", and the introduction still talks about the intent and transition mechanisms to replace jCard, we can be a bit clearer that jsContact is a second standard, at least until jCard can be deprecated from support in RDAP after jsContact is sufficiently supported.

When we all agree jsContact is a second standards track document not intended to deprecate jCard just yet today, then that’s fine.
If we don’t get feedback this document should have a different status than standards track, then the chairs will add that intended status next week.

Which leaves the remaining questions Mario posted in his original message.

We have many similar use cases for standards track extensions in EPP, where the RFCs couldn't envision a feature or an approach that comes up later.  The jscontact draft needs to be defined as an RDAP extension that is optional, with the appropriate signaling, and with transition considerations to support a transition from the jCard defined in RFC 9083 to JSContact defined in the extension.  I don't foresee that support for jCard will go away, but that JSContact can be become an alternative and potentially a preferred format for the RDAP contact data.  As Scott points out, supporting multiple formats can add complexity, but I believe that is a known cost to progress.

There will be only less work if one is implementing a client in the future after the whole ecosystem had moved to JSContact, therefore no need to implement jCard, which is still a good win, as I guess that many haven’t implemented a client yet since whois is still dominant and RDAP is not yet at the same level.
