ebXML Registry does not expose an explicit and distinct interface for 
the repository.
All access to the repository is through the registry interfaces 
(QueryManager and LifeCycleManager).
This does not seem to be an issue so far.

Call it my personal bias but I do not think that *MOST* centralized 
things are not a good idea.

That said, ebXML Registry architecture is flexible. One can operate a 
giant, monolithic, centralized
ebXML Registry using the current specs. Or one can operate many smaller 
ebXML Registries that can federate
together in a loosely coupled manner. The effect to the end user is the 
same. A federation of registries look like
one giant monolithic registry as far as discovery is concerned. However, 
a federation scales better and has better distributed
owebrship and management.

Take your example. Lets say the automobile industry operates several 
ebXML Registries that form an
automobile industry federation. Now an tire manufactures can register 
themselves in *ANY ONE* (and only one) of those registries
(say "tire manufactures" registry) and they will be discoverable from 
*ANY ONE* of the registries in the federation.

Does that clarify the architecture.
