[digiKam-users] Change in metadata engine

I ran some test using the same database in Digikam 7.3, and I noticed
the same behavior, so it's probably not something that happened from
digikam 7.3 and 7.4. Most of these pictures were first tagged using
digikam 5.9 or digikam 6.0, and they were lacking most XML metadata.
However, previous versions of digikam put them in their correct place
within the hierarchy, for some reason it don't fully understand. I still
have to check if merging a tag with the one in the proper place of the
hierarchy writes all the necessary XML metadata so the problem does not
reappear with that picture.
In any case, the issue with the keywords in iPhone pictures is still
there and it's quite annoying, since the only workaround I have found is
to complete recreate the metadata for the images using exiftool outside
