Re: All this buisiness about namespace URNs...

It amuses me to see how far off topic my posting got.  And so quickly.  With everyone fixating on a poorly worded clause of mine, I though I better try again, to see if I could improve on my rambling.  This time, I will pose it as 3 simplified questions:

1) If (as has ben debated on this list) we are worried about URLs because they are not unique and change over time and do not have "ownership" without adding the HTTP protocol, then why don't we invent an ID for name spaces that   IS   globally unique?

2) Are we really that worried about collisions?  If I just used "mynamespace.myproject.Novell.com" as a name space ID, what are the odds that I will ever see any accidental collisions?  And if someone intends to collide with me, then what recourse would I have with any other identifier? 

3) Why isn't our name space identifier two parts:  1) the name spaces name/ID that uniquely identifies it, and 2) the last known, or probable location of the information about the name space.  The advantages of this are: a) I can still uniquely identify the name space no matter where it is moved, b) I can retrieve information about the name space and c) if that information is moved, there may be some hope of searching for it and updating it's location.  Think of it as an ID/URL combination with the URL part optional, but a true URL.

This being where an industry-wide standards organization fills the void 
and develops the elements, attributes, etc., for all entities doing 
business in that industry. If such DTD's (x-schema's, whatever) are in 
place, communication within the industry would be seamless. The 
complication arises when trying to exchange data outside the industry.

That's why I fall into the camp of having the namespace designator 
actually point to a document that is retrievable and explains the data 
being sent.

Take Care,

At this point, I don't think that's the best
option.
