In match and merge, survivorship rules promote information from exactly one source to exactly one target by comparing information from the source with information from the target and writing the relevant updates to the target.
- In the match and merge IIEP and match and merge web service endpoint, information is promoted from incoming entities to existing or newly created golden records.
- In the matching event processing and in the clerical review Web UI, information is promoted from non-surviving golden records to surviving golden records as those records are merged.
- In the unmerge Web UI actions, as the association between source records and golden records are changed, the content of the resulting golden records is resolved.
