I'm wondering if we should consider a similar DNS-basis for "private" URI schemes. I've been late in producing a new version of http://www.ietf.org/internet-drafts/draft-king-vnd-urlscheme-03.txt partly because of my uneasiness with IANA getting into the business of registering organization names.

Hi,
I wanted to express my *strong* support for the recently published draft about the "dns" media type registration tree[1]. I think this is long overdue, and I thank Mark for devising such a straightforward mechanism for decentralizing the media type assignment process (you don't want to know what I was going to propose 8-).
I would like to propose one substantive change to the document though.
As I see it, there are two objectives that we'd really like to achieve; a decentralized namespace, and dereferenceable identifiers (for all the reasons in [2]). Mark's draft ably addresses the former, but doesn't seem to treat the latter as an objective, although the "doc" parameter is a step in that direction. I think a fairly small tweak can give us both.
What I propose is that the doc parameter be replaced by a "base" parameter whose value is a URI that is intended to permit the media type name itself to be used as a relative URI. For example, if we had the media type "text/dns.foo.example.com", with a base parameter value of "http://example.com/mtype/" then the authoritative URI for the media type would be "http://example.com/mtype/text/dns.foo.example.com" (see the discussion[3] about the relative URI approach by the W3C TAG). The document should be clear that the resultant URI is the authoritative URI for the media type. It would still be optional, though I'd like to say that we recommend that it SHOULD be used, and SHOULD be dereferenceable using currently ubiquitous technologies.
Thoughts?
