Anything new here? I just stumbled again over this...
I mean apparently we won't likely get any "standard" here soon,... i.e.. a
specified behaviour on what happens with the meta-data in sidecar files:
1) do they completely replace the image-metadata?
2) do they get merged per property (probably in the sense of "overriding")
image-metadata?
3) is there a more complex merging i.e. that some properties are only merged as
group like if the image contains GPS-Lon, GPS-Lat and GPS-Alt ... but the
sidecar file contains only GPS-Lon, GPS-Lat then these two will be taken but
GPS-Alt will be "cleared"
So could digikam simply offer at least (1) and (2)? They don't seem to be too
difficult to implement...
I guess on would need a configuration option for how sidecar files are read and
one for how they are written.
Right now I just tried to change the orientation of an image... and I got that:

I what I'd prefer however is rather something like.

</x:xmpmeta>
- I don't need the photoshop crap,... so there should be some checkbox
somewhere, whether these fields are written per default.
- Since that was a TIFF file, and the orientation is apparently stored in some
TIFF properties,... I don't need any Exif either (I haven't changed it)
- All the other TIFF properties weren't changed, so they shouldn't appear
either.
- Neither have I changed the digikam Labels... so I guess those should be
dropped, too, and as a consequence the namespace as well.
Cheers,
Chris.
