It appears that soic:User adds a level of indirection for some cases that don't occur too often. Perhaps this stems from how "people" are represented in CM tools, the CM tool has an internal model and storage for its concept of a user. This may reference to some other repository or have some key into that, employee id or employee email. Perhaps the best way to look at this is to take a couple concrete examples. Here's how I'd see it playing out using the approach that is currently laid out in the V2 spec. Could you provide an example of this would be done using soic:User and why what I have is not sufficient? <oslc_cm:ChangeRequest xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"; xmlns:dc="http://purl.org/dc/terms/"; xmlns:oslc_cm="http://open-services.net/xmlns/cm/1.0/"; rdf:about="http://example.com/bugs/2314";> (snip)... <dc:creator> <foaf:Person rdf:about="http://example.com/users/joesbot";> <foaf:name>Joe's Bot</foaf:name> <foaf:nick>bot</foaf:nick> <foaf:mbox rdf:resource="mailto:jbot@nowhere"; /> <foaf:img rdf:resource="/user-images/robot.jpg" /> </foaf:Person> </dc:creator> <oslc_cm:owner> <foaf:Person rdf:about="http://example.com/users/bob";> <foaf:name>Bob Boss</foaf:name> <foaf:nick>bob</foaf:nick> <foaf:mbox rdf:resource="mailto:bob@nowhere"; /> <foaf:img rdf:resource="/user-images/bobb.jpg"/> </foaf:Person> </oslc_cm:owner> </oslc_cm:ChangeRequest> Thanks, Steve Speicher | IBM Rational Software | (919) 254-0645
