Right now, the URI working group is suggesting that people write
internet drafts describing their new URL schemes and discuss them on
the URI mailing list (uri@bunyip.com). Eventually the URI group needs
to come up with a better registration procedure; if you have a
suggestion for such a registration procedure, please make it on the
URI mailing list.
There was quite a bit of discussion on the 'mailserver' URL, for
example.
For some kinds of resources, it isn't reasonable to pack everything
needed to access the resource into a single URL-like string; in those
cases, the way one usually handles this is to make a link (http: for
example) to a resource whose mime-type is a sesson description.
You retrieve the session description object, and then launch (via
.mailcap) the helper application that interprets the session
description by initiating the session.
I think this is a difficult design choice. Currently, most web
browsers are more flexible about adding more media types than they are
about adding new URL schemes.
