The IETF _should_not_ standardise on an object system architecture.
It should develop architectural frameworks within which future object
system architectures can exist and be exploited.

It shouldn't happen in the URI working group.  It's an accident of
history that the subject has been raised again.

BUT: as a matter of principle, the URI group should not ignore the
existing standards, neither should it close off desirable future
development pathways.

Strongly agreed.

As I've said already, SOM is supposed to be CORBA compliant.  IBM
signed the CORBA 2.0 spec.  I can't speak for Microsoft, but they have
said that OLE will be CORBA interoperable.  Sticking with CORBA, there
isn't a problem in defining URCs, except that there is as yet no
specified mapping of CORBA to SGML.

This way round, it seems that one could define URNs to be understood
as CORBA tagged profiles and use an ORB to provide a resolution

Strongly agreed.
