The problem: if the external id's supplied to the MPI originated from different organizations then they reflect the fact that the entity is a patient in two different contexts. To put it another way: the person in question is a patient twice-over. The identifiers are therefore not synonymous. [An interesting wrinkle on this that the role instances could in fact have the *same* numeric identifier but issued by different scopers (with different OID's).] The id created by the MPI reflects neither of these scopers, but is some other kind of artifact entirely. Arguably, it is not even a 'patient' role id. Robert grant 01:12, 2 Jun 2006 (CDT)

I agree, it is probably more of an "IdentifiedEntity" role. That is however not the entry point of the PatientLivingsubject registry model.. Note that the wiki page distinguishes a couple of different scenario's (1. return information based on some role id, 2. return information based on some role that has a specified scoper). There definitely still are open issues in this area. Rene spronk 06:19, 2 Jun 2006 (CDT)
