Hi Phil,
I noticed that The Gimp put in
[XMP-exif] Copyright : [None] (Photographer) - [None] (Editor)
but in the your documentation for xmp tags, although there seem to be several copyright tags, there isn't one under xmp-exif.
Hi Alan,
I just checked the Exif 2.3 metadata for XMP specification (http://www.cipa.jp/english/hyoujunka/kikaku/pdf/DC-010-2012_E.pdf) and EXIF:Copyright is mapped into XMP-dc:Rights. Hence there is no official XMP-exif:Copyright tag. I think the Gimp implementation is flawed.

Thanks Phil.
I tried to delete it but couldn't. :( Is there a way for exiftool to do this?
alan@egremont:2013-07$ exiftool -xmp-exif:copyright temp_cr.jpg
Copyright : [None] (Photographer) - [None] (Editor)
alan@egremont:2013-07$ exiftool -xmp-exif:copyright= temp_cr.jpg
Warning: Tag 'xmp-exif:Copyright' does not exist
Nothing to do.
I mentioned your name on Gimp Bugzilla https://bugzilla.gnome.org/show_bug.cgi?id=704697 (https://bugzilla.gnome.org/show_bug.cgi?id=704697) I hope that is OK?
Sure. There are a few ways to delete this. The recommended way would be to create a user-defined tag. The lazy way would be to delete all XMP tags not writable by ExifTool, but this may catch some others too:
exiftool -xmp:all= -tagsfromfile @ "-all:all<xmp:all" FILE
Note that I did "-all:all<xmp:all" instead of just "-xmp:all" because the latter may commute same-named tags to the preferred XMP namespace, which you wouldn't want.

Looks like the problem with the Gimp is a tad larger than I thought

Wow, yes.
Some of these weren't copied because they are the wrong format. Others weren't copied because they should be XMP-tiff, not XMP-exif. The ones written to the wrong namespace may be fixed by using "-xmp:all" when copying back the tags (as I mentioned in my last post), but this may also move some other tags around too.
Looks like somebody at Gimp should actually read the specification.

Phil, did you receive the email about this?
https://bugzilla.gnome.org/show_bug.cgi?id=704697
They say it is fixed.
No, I didn't register for notifications about this.
Glad it got fixed. Sounds like a major overhaul (watch for other bugs being introduced).
