[ebxml-dev] ......some form of centralized repository is NOT neededRE: [ebxm l-dev] RE: [EDI-L] Article on ebXML Core Components

I would view ebXML Registry as a generic engine / service to classify,
associate, search, and manage the life cycle of any information asset. 
It can be used internally to a business as a Knowledge Management engine
(structured, unstructured data).  Its a standard based approach to some of
the offerings by the KM vendors.  As a example that departs from B2B,
individuals could classify their own documents on their personal desktops,
and a P2P binding would allow federated searches across the enterprise ("who
has done work on such and such a topic?").   UDDI has a specific purpose.

There are some fundamental issues that might prevent this as well as the
political 
ones.

UDDI is a registry only...no repository, where as ebXML has both.  That
could (and 
may need to be) rectified by the UDDI spec (imagine 10,000 WSDL
definitions 
pointed to by a UDDI rep.....how would you manage the storage of all
these in a large 
corporation in a doable fashion?  Put them on different web servers all
over the 
company?  Not likely......some form of centralized repository will
eventually be 
needed to complement UDDI).

The big issue is that UDDI has been designed to be a "global" public
directory 
(though that does not preclude private implementations), with support
for federation 
and distribution of nodes (meaning that the distributed system appears
as a single 
global registry).  Whereas ebXML RegRep has been designed as a
community-level 
registry, to target a specific group of parties with a common interest
(a supply chain, 
industry vertical, etc.) and no provision has been made for
distribution/federation.  
Those are big chasms to cross in trying to merge the two together.
Different 
philosophical roots.

Best practice seems to suggest that you use ebXML RegRep for community
stuff, 
and use UDDI more globally which in turn has a "pointer" to the specific
RegRep.
