Description karlgustavv23 2015-09-14 20:23:16 UTC

In Settings -> Configure -> Metadata -> Behavior: "Rescan file when files are modified" is set.

If you externally add a tag (e.g. via exiftool) and restart digiKam this new tag will appear in the tags list and the tool-tip will show it, too.

If you externally remove a tag (e.g. via exiftool) and restart digiKam this removed tag will stay in the tags list and the tool-tip will continue to show it, too.

Reproducible: Always

Steps to Reproduce:
1. Add a tag via exiftool (exiftool -subject+=Test -keywords+=Test test.jpg)
2. Open digiKam
3. See the tag appear
4. Close digiKam
5. Remove a tag via exiftool (exiftool -subject-=Test -keywords-=Test test.jpg)
6. Open digiKam
7. The tag is still there

Actual Results:  
The tag is still there

Expected Results:  
The tag should be removed

Comment 1 Marcus Hardt 2015-11-15 11:41:20 UTC

I can confirm this for the "Rating" Tag and Digikam 4.4.0.

Changing the tag via exiftool -TAG -Rating=2 <filename> will not be reflected in digikam.

Even if I copy the file to a different name it is not shown.

If I modify Rating via exiftool before digikam sees the file for the first time, it works well.

You need to use Re-Read metadata function in digiKam to update the file properties in database.
