# This sample shows how to carry on a manual modification of DICOM
# tags spread accross various levels (Patient/Study/Series/Instance)
# that would normally forbidden as such by the REST API of Orthanc to
# avoid breaking the DICOM hierarchy. This sample can be useful for
# more complex anonymization/modification scenarios, or for optimizing
# the disk usage (the original and the modified instances never
# coexist).
