Hi Florian,

(Apologies if I’m repeating something another AD may have already told you.)

The ART ADs have discussed this, and we wonder why this needs to be an IETF stream RFC.

The URI schemes registry is only “first come first serve” *FCFS) for provisional schemes. FCFS registration does not require an RFC.  I see that the draft requests a permanent scheme, however “permanent” status is not appropriate for a new scheme. The normal procedure is to register it as provisional, and later promote it to permanent if it sees widespread use.

Based on that, we don’t see the need to spend DISPATCH agenda time on it. Is there some reason that we are missing?

Thanks!

Ben.
