ACTION: write up ebXML registry UC

(Resending  after adding links to ebXML Registry. Dan, please let me 
know if this is what you were expecting. Thanks in advance for comments 
and suggestions from WG members.)

Below is a first draft of a proposed ebXML Registry use case. I am 
sending it in HTML format for easier integration into document. Let me 
know if this is inconvenient to anyone and I will resend.


      n.m Searching and Browsing an Ontology Repository

Peter is developing a medical knowledge base using OWL 
<http://www.w3.org/2001/sw/WebOnt>/RDF in collaboration with medical 
domain experts all over the world. The knowledge base is used within 
electronic patient records <http://xml.coverpages.org/hl7PRA.html>. To 
facilitate collaboration and avoid duplication the team is using a 
federated ebXML Registry 
<http://ebxmlrr.sourceforge.net/presentations/xmlEurope2004/04-02-02.pdf> 
to store the knowledge base they are building. When adding a new concept 
to the knowledge base Peter uses a Registry Browser 
<http://ebxmlrr.sourceforge.net/3.0/registryBrowser> application to 
search the ebXML Registry for similar or related concepts. The Registry 
Browser allows Peter to choose a parameterized query 
<http://ebxmlrr.sourceforge.net/3.0/registryBrowser/discovery.html#Adhoc%20Queries> 
from a set of  pre-configured parameterized queries and offers a form 
that Peter uses to enter the query parameters. Peter enters a few 
parameters and issues the query. The ebXML Registry returns a large 
number of matching results 
<http://ebxmlrr.sourceforge.net/3.0/registryBrowser/discovery.html#Search%20Results%20Panel>. 
Peter, narrows his search by re-issuing the query with additional 
parameters until he find concepts that are most relevant to his concept. 
Peter now drills down and browses 
<http://ebxmlrr.sourceforge.net/3.0/registryBrowser/browsing.html> these 
concepts, their related concepts and meta data to determine whether to 
add his new Concept or not.

*Motivates:* RDF Graph Pattern Matching 
<http://www.w3.org/TR/rdf-dawg-uc/#r3.1>, Variable Binding Results 
<http://www.w3.org/TR/rdf-dawg-uc/#r3.2>. Iterative Queries
