The definition of 'same' that you are using is perfectly reasonable to you but might be completely unreasonable to someone else. I personally don't agree with it since I have no real garuantee that oclc.org will remain under OCLC's control since domain-names are re-assignable. We spent a large amount of time way back when realizing that 'sameness' with respect to URIs has many 'flavors', only one being universal for all cases in which a URI can be used. -MM
