I have found a possible solution --- can anyone check that it will not
create problems?
Basically, if the .xmp file already exists, I will do:
exiftool -"xmp:HierarchicalSubject+=mytag" -"xmp:Subject+=mytag"
p1050786.rw2.xmp
...and if the .xmp file does not exist, I will do:
exiftool -"xmp:HierarchicalSubject+=mytag" -"xmp:Subject+=mytag"
p1050788.rw2 -o p1050788.rw2.xmp
Does it sound safe? Should I set both "Subject" and
"HierarchicalSubject" tags or with one is sufficient?
Thank you!
