Subject: Next steps on draft-zigmond-tv-url-02

So now that we've officially moved discussion of the recently submitted
"tv:" draft to this list...all discussion seems to have stopped.  I thought
I'd send out a message on where I think we are and how we might move
forward.

Good news: There seems to be some emerging consensus that a revision of the
"tv:" spec should be published as an RFC.

Bad news: At the very least, the scheme needs to be revised for global
uniqueness.

The proposals on the table that seem the most workable to me are the ones
using DNS.  I don't think we want to try to create a new registry system for
television networks, especially if we hope to finish soon.  So the revised
scheme would look like:

	tv:		(current channel)
	tv:kqed 		(ITU standard international callsign)
	tv:abc.com	(DNS domain name: American Broadcasting Company)
	tv:abc.net.au	(DNS domain name: Australian Broadcast Corporation)

We could make a note in the draft of the legacy usage of "tv:abc", but
explain that it should not be used going forward because of collision with
the callsign namespace and the problem of the same identifiers being used by
different broadcasters in different geographical regions.

We would also remove from the draft the speculation on future "tv:" URI
schemes, and remove the IPR statements (which could be filed by individual
companies with the IETF separately).  

How does this sound?

	Dan
