RE: Significant W3C Confusion over Namespace Meaning and Policy

Hi Didier:

One way to look at it in context of the current thread is 
that the namespace doesn't identify the *collection*, it 
identifies the *collector* which might be a policy, a 
standard or a program.  The problem is static 
names for dynamic collections.  Either a separate 
flag is required (eg, a version att) or the name has 
to direct to the authority.  As you point out, if the 
system is dynamic, that's better.  No free lunch.  

BTW: I said 'one way' to look at it.  As Patrick points 
out, the most conservative position is that it isn't 
an identifier or a locator, it is just syntax for 
walling off names and has no implications for sets 
or semantics.  Even calling that a "name" is weak. 
Its 'meaning' is its value (UniqueWallZed).

Of course, that reduces the utility of it considerably 
and it doesn't matter if a URI or a URN or a URL is 
there.  In fact, it doesn't matter if it is a URanything, 
just a unique wall.

Hi Len,

Interesting, this is in the same vein as the actually sleeping trend in OO
about reflectivity. If the system can be reflective enough to provide some
meta information about itself its easier to adapt to it. For instance, we
made some progresses in newer systems like Java or .NET when these latter
provide some information about what is contained in an object. In other
words, tell you more about its type definition. Every time a system becomes
more reflective it also becomes more adaptable or it is more self
documenting.

Cheers
