--- Comment #23 from Andrew Goodbody <ajg02 at elfringham.co.uk> ---
I think that two or more ideas are being conflated here.
This is not a request for digikam to auto-remove tags that are not present in
the db. ie it is not a request for strong synchronisation of tags. That would
be the wrong way to fix this issue IMO.
It is a request for changes made to the tags hierarchy to be reflected in all
images containing those tags. So only those tags changed should be updated but
it should be done in all relevant images. It should not affect other tags
already applied to the image regardless of whether they exist in the digikam db
or not.
I struggle to believe that anyone would want the result of moving a tag in a
hierarchy to actually just be to copy it to a new location or if they delete a
tag, for it to not actually be deleted. Which is actually what the current
behaviour is.
If there is a desire to have a history of changes made to tags that could be
done as part of non-destructive editing and versioning. It does not mean that
this bug should not be fixed as requested.
