After a merge, the patient identifier PID-3 represents all records formerly represented by either MRG-1 or PID-3. All other fields may be ignored. The following conditions shall be detected by the Document Registry. Messages containing these conditions shall not update the state of the Document Registry. The subsumed patient identifier is not issued by the correct Assigning Authority according to the Affinity Domain configuration. The surviving patient identifier is not issued by the correct Assigning Authority according to the Affinity Domain configuration. The subsumed and surviving patient identifiers are the same. The subsumed patient identifier has already been subsumed by an earlier message. The surviving patient identifier has already been subsumed by and earlier message. Both the subsumed and surviving patient identifier must convey a currently active patient identifier known to the Registry Actor. If none of the above conditions occur then the Document Registry Actor shall perform the following duties: Records the merge. Only the subsumed and surviving patient identifiers need be remembered. A patient identifier merge affects the processing of future Register Document Set-b [ITI-42] transactions. See ITI TF-3: 4.3.1.2.4 XDS Registry Enforcement of Attributes and ITI TF-3: 4.3.1.2.5 XDS Registry Responsibilities for more details. Multiple merge transactions can form a recorded merge chain, where the Subsumed identifier of the current merge is the Surviving identifier of a previous merge. Register Document Set-b transactions referencing a subsumed identifier are rejected with an XdsUnknownPatientId error. Registry Stored Query transactions referencing a subsumed identifier return no content. Registry Stored Query transactions referencing a surviving identifier successfully match the entire recorded merge chain and return appropriate metadata.
