[comment TODO: "URI" should actually not be a valueType since it is not OSLC-standard. However, this is one way to allow user to specify a URI as a type.
Another approach would be to have a valueType as String, and the Range being set to "URI", hence creating a URI (local) resource? 
But I really want the user to be able to map to java.net.URI, just like they can map to String or Boolean - without having to create a resource for that. /]
