UDDI Classification vs. ebXML RR Classification

[Matthew MacKenzie <matt@xmlglobal.com>]

It seems that in ebXML RR, classification trees are requested and traversed without
any prior knowledge of the classification taxonomies, the classification is given to
the user dynamically.  This approach is certainly very flexible for allowing arbitrary
taxonomies to be introduced in certain industries, but presents a problem when an
attempt is made to integrate with UDDI.

UDDI expects the browser to know about the classification taxonomies.  At
UDDI.microsoft.com, if I wanted to find businesses that are associated with Apparel,
Luggage and Personal Care Products, I would need to do
search that essentially says: find businesses with a UNSPC code of 53.

Should ebXML RR support a number of taxonomies such as UNSPC, NAICS, SIC and GeoWeb,
as UDDI does, and have an option of supplying the classification tree based on a list
of taxonomies that the
client is interested in, for instance:

ObjectQueryManager->getClassificationTree("UNSPC")
