That sounds a bit like overkill in this case, when it would be enough to have 
a way to apply changes automatically to all versions of an image (which seems 
to be what OP wanted). Also, -TagsFromFile copies *all* metadata tags, unless 
you specify otherwise. Not much of a problem between versions of one image, 
not nice between different images...

(note: Exiftool tags cover all metadata. Digikam tags are only the /keywords/ 
the user applies to an image, which is a small subset of Exiftool tags. To 
complicate things further, there are at least 3 tags under which keywords can 
be stored

But I agree that a way to copy metadata from one image to another could be 
very useful, *if* I can select which metadata get copied (at least to a level 
where I can select one or more of title/caption, tags, ratings, labels, owner/
rights information, geolocation, ...). And such a copy function must be very 
careful /not/ to touch any of the "hardware-related" metadata (original date, 
aperture etc.).
