It looks to me as if Linux could really do with a version of
Exiftool GUI; that would allow easier bulk metadata manipulation.
Possibly it would run under Wine.<br>

Thanks for your answer, and sorry to have been a bit long to
answer ... days seem to be way too short at the moment! <br>

<br>
Here's one possible approach. To be on the safe side, first
create<br>
backup copies of all the images and put them somewhere digiKam
isn't<br>
looking. Also make a backup copy of the digiKam database.<br>
<br>
Then use exiftool to locate and delete all the tagging
metadata from<br>
the images themselves (from the images digiKam is managing,
not from<br>
the backup copies). Also delete any digiKam XMP sidecar files.<br>

That's the easy and quick thing to be done.<br>

<blockquote class="gmail_quote">
<br>
Temporarily set digiKam up to not write any metadata to images
or to<br>
digiKam xmp sidecar files (just write to the database) and
clean up<br>
the tag tree in the digiKam database. It goes a lot faster if
digiKam<br>
is writing only to the database, and you can delete and
rearrange tags<br>
without fear of creating a new set of unwanted tags.<br>
<br>
When you are finished deleting and rearranging all the tags in
the<br>
database, there won't be any remnant unwanted tags in the
image<br>
metadata (having removed them with exiftool) or in any
existing XMP<br>
sidecars (because they were already deleted). So when
everything is<br>
exactly like you want, you can write out the desired tag trees
to XMP<br>
sidecars or back to the image files, whichever you want. And
this time<br>
digiKam won't get confused when it "synchronizes" while
writing out<br>
the tags.<br>

Thing is the whole procedure will take quite some time, and I
don't know when I'll be able to do that as I need my Digikam
to add new pictures several times a week.<br>
I can keep separated picture files on different removable hard
disc; but I understand Digikam can handle only one DB per
installation ... unless I create a special user (having his
own Digikam DB in his /home) for doing the job on the old
pictures, while I use a new DK installation in my own /home to
handle the pictures that keep coming week after week.<br>
<br>
Once the job is done, I could reimport the "old" pictures in
the new installation.<br>
Would it be feasible like that?<br>

Send me a private email and I can help with the exiftool
commands.<br>
digiKam writes tags, captions, rating, and etc to a number of<br>
different locations (eg digiKam xmp tags, lightroom xmp tags,<br>
microsoft xmp tags), and exiftool can remove whatever needs to
be<br>
removed.<br>

Couldn't you send them to the mailing-list? I guess I'm not
the only one to have mess to clean up ....<br>

<br>
I just went through this procedure with all of my own images
and I<br>
took notes along the way. I ended up finding and removing a
ton of<br>
old, unwanted metadata left behind by various DAM softwares
that I've<br>
used at one time or another.<br>
