RE: [ebxml-cppa] CPP identification revisited

[Dale Moberg <dmoberg@cyclonecommerce.com>]

I think we should definitely drop the entire Note about 
Registry identifiers for CPPs. 

The cppid identifier is supposed to
be unique, as we now say in v1.07. That
should give implementers an identifier
for a CPP.

Do we need to add a scope
for globally, universally, cross-all
actual-and-alternative-universes uniqueness?

The original uniqueness intent was unique
within CPPs of a Party, which is less
than globally unique. Maybe we should state the scope
within which uniqueness is to be assured?

URN resolution process is still not very
well-defined, standardized, or even
with a de facto practice, as far as I can tell from
the IETF URN WG RFC list. I think that is a 3.0
goal to explain how using URNs will support interop while
allowing extensions.

It's far from that simple.  The Registry assigned unique identifier
identifies it uniquely within one specific registry instance, not
globally.


 Does anyone remember the arguments on this from last year?

Yes - it is a bone of contention accross a few teams.  CC, BP and
Architecture are all affected.  I have an action item to discuss this
within architecture.

A URN resolution shceme may be our best bet although no single
consistent methodology exists for this.
