Subject: Re: [xml-dev] DNS based URIs that don't imply access method

Ok.  I've also asked this question on the ietf list and appears 
that there does not exist a URI scheme with these properties:

  - it uses DNS to gaurentee uniqueness
  - it does not imply any sort of access protocol (http/ftp/etc.)
  - two instances of the scheme are unique iff their strings are unique

So.  I'm now asking if we should create a URI scheme with these
properties.  Let's call it "pkg" for now, but any sufficiently 
generic name should work.   Here is the proposal:

  - the scheme starts with "pkg://"
  - next is a domain name in *small caps*
  - optionally followed by:
    - a slash '/'
    - a standard httpish path per URI specification.
  - no relative forms
  - no fragments



The end goal is (a) to have a DNS based URN and (b) not have
this URN imply any sort of access mechanism (http,ftp,etc.)

For XML-DEV people...  What do you think?   Pretend for a moment that 
this is 1997 and XML is just about to emerge.  Would something like this 
have helped?   Please limit comments to what the URI change will impact,
not about general problems with XML namespaces and such soap boxes.
Ok.  Now, given today, if it took a while to catch on would it improve 
the situation (mod other namespace problems)?  If not, why?

Anyway, if you are interested, I'm going to attempt to carry
out this conversation over on the ietf's discussion list at
in a manner independent of XML.  I'll be observant of replys 
to the xml-dev list, but I'm not at all interested in the
xml-namespace soapbox.  ;)
