Description MarcP 2021-09-19 10:36:43 UTC 
SUMMARY
I don't know if it's technically a bug or an improvement suggestion.

Let's say you scan for faces in a new batch of pictures. Some suggestions appear in the People tab.

Now imagine that from another computer, using the same pictures, scan them for faces and you tag the people in it. Data is saved in the picture metadata.

The next time you open the first computer, these changes will be detected, and the new metadata will be loaded onto digikam. However, the face suggestions will remain in the People tab as if they are still unknown.

I believe they should disappear if that face has already been tagged.


STEPS TO REPRODUCE
1. Computer 1: scan for faces and wait for results.
2. Computer 2: do the same and tag the faces. Save metadata to files.
3. Computer 1: re-read the metadata.

OBSERVED RESULT
Computer 1: new metadata will be read (including face region metadata in XMP), but the the face suggestions will still be there, as if the person is unknown.

EXPECTED RESULT
Face suggestions that have already been tagged in the metadata should be updated, and disappear if the person has already been identified.
