Perfect. It really works in Exiftool.
Problem is it is not working in LUA script, because the script will not handle double " "
I tried:

A) cmd_options[1] = “-IPTC:Keywords<xmp-dc:Subject” “-IPTC:ObjectName<xmp-dc:Title”

B) I tried also directly into:
exif_cmd = “exiftool “…””"…tostring("-IPTC:Keywords<xmp-dc:Subject" “-IPTC:Keywords<xmp-dc:Subject”)…"""…" -overwrite_original “…”"" … imgexp … “”"

But script will not run at all with any of these options.
