If my memory is correct, we've had the discussion about completely stable registry URLs with IANA a few times, each time with a result more or less equivalent to your "20+ years" concern. That concern is increased by periodic discussions about the possibility of splitting up components of the IANA function(s). However, I wonder whether we might be able to reach an agreement with them to maintain a stable search format, e.g., to make something like http://protocol-registries.iana.org/?registry="Registry-Name"; work permanently and stably for all protocol parameter registries. john --On Sunday, April 18, 2010 23:10 +0300 Jari Arkko <jari.arkko@xxxxxxxxx> wrote: > I agree of course that uniqueness should be a MUST. > > But while I don't feel strongly about this, I'm actually a > little reluctant to put permanent URIs to RFC.
