I should have said that above quote applies to pilots where there 
already was an existing XML format. In cases where there was no existing 
format, we have seen both flavors: a) Binding to RIM only and b) XML 
Schema + RIM binding

Experience with several pilots suggest that an XML format is needed 
under the following situations:

-There is a unique and specific Business Information Model which defines 
unique and specific Business Objects (e.g. HL 7 Conformance Profile, 
Patient Medical Record, Purchase Order, RosettaNet PIP, OAG BOD)

-The Business Object is more content than metadata in the role that it plays

-The Business Object is fairly complex

-XML documents representing the Business Object need to be exposed

We have also found that it is generally good practice to keep a good 
separation between content and metadata. ebXML Registry manages both 
well when it comes to LifeCycleMangement. However, ebRIM is all about 
Metadata and not content.
It should be kept in mind that some aspects of the content may be mapped 
to metadata in the RIM binding.

While it is possible to map all the content into metadata,  it is more 
effective use of ebXML Registry to:

-Define a CCTS Business Information Model (CCTS BIM) in UML

-Define a mapping of  CCTS BIM to XML Schema

-Define a mapping of CCTS BIM to ebRIM. Such a mapping clearly 
identifies the binding of CCTS BIM to ebRIM metadata and should include 
 a  Catalog Definition File (XSLT Style Sheet). Such a mapping also 
defined BIM specific custom queries that address many anticipated query 
use cases.

The benefit of above approach is that a Core Component in XML form is in 
its BIM form and not as a generic ebRIM form. This would allow people to 
grasp it better. Meanwhile when a CC is submitted to the registry it 
automatically gets cataloged with generated ebRIM metadata and is 
immediately discoverable using content based queries.
