The mandatory argument indicates the metadata fields in the dublin_file to be added unless already present (multiple fields should be separated by a semicolon ';').
However, duplicate fields will not be added to the item metadata without warning or error.
One probable scenario for using this tool is where there is an external primary data source for which the DSpace instance is a secondary or down-stream system.
Metadata and/or bitstream content changes in the primary system can be exported to the simple archive format to be used by Item Update to synchronize the changes.
This file lists the bitstreams to be deleted, one bitstream ID per line.
Currently, no other identifiers for bitstreams are usable for this function.
