Special Parameters for FHIR update

• if extra query parameter ext:deactivateExistent == true then the existing resource is not deleted, only deactivated. It is recommended for huge stores/indexes due to high costs of updates in quad stores.

• if the resource should be visible in the navigator group tree then the FHIR resource should have a group name. The definition of the group name (and the default language) is done by a FHIR extension element:
