It looks like the persons reference from Group to Person is a
containment reference. You have to change the GenModel property for
"Containment Proxies" to true. Then you will be able to put a Person in
a different resource than its containing Group. Simply create each
resource with the URI you want and add each Person to its own resource.
When you have the resources all set up, save them all.
