2. Go to tab "Tags"
3. Select a tag
4. Click apply
5. Click "more"->"write tags to each file" (Only works with more than one file selected.
6. Observe file tags with exiftool 

OBSERVED RESULT

Comment 1 Maik Qualmann 2020-11-13 11:44:34 UTC

What kind of image is it, JPEG or RAW? Have you activated the writing of metadata for tags in the digikam metadata setup?

Maik

Comment 2 Marcus Hardt 2020-11-13 12:33:01 UTC

I'm using only JPEG.

I have not activated the "if possible write Metadata to RAW files" option. Semt too dangerous.  Shall I do that?

Comment 3 Maik Qualmann 2020-11-13 12:50:17 UTC

You do not need to activate the writing of metadata in RAW files if you are using JPEG. Have you activated writing to tags on the same tab above?

Maik

Comment 4 Marcus Hardt 2020-11-13 12:51:09 UTC

Yep. There I've activated all (but "Face Tags")

Comment 5 Maik Qualmann 2020-11-13 12:56:53 UTC

Ok, run digiKam in a terminal and give us the log when you've written a tag.

Activate debug before:
----------------------------------------
export QT_LOGGING_RULES="digikam*=true"

Wow... this is verbose...

I've cut some stuff away.

Comment 7 Marcus Hardt 2020-11-13 16:21:49 UTC

Sorry for the delay; Didn't notice the collision warning..

Comment 8 Maik Qualmann 2020-11-13 19:04:53 UTC

The log looks good. I don't remember a bug in digiKam-6.4.0 that could cause this problem. The tag "must" been written into the image. What does the metadata display in the right sidebar tab of digiKam show? Possibly provide a test image with a written tag.

Maik

Comment 9 Marcus Hardt 2020-11-17 21:25:15 UTC

It was a sad configuration that got me confused: Two hosts on NFS and a local copy.

Sorry for the noise and many thanks for the immediate help!!

Comment 10 Marcus Hardt 2020-11-19 09:29:00 UTC

I'm just having the inverse problem now:

I have verified that I'm using the right folder (sigh)

I have verfified (with exiftool) that the tags were written to the files

I have started another digikam instance on the 2nd host. 
That one fails to show the new tags.

Using 'right-mouse -> refresh' on the album does not help.

What can I do?

Comment 11 Maik Qualmann 2020-11-19 20:59:33 UTC

It's hard to tell what's wrong. Note that the automatic album monitoring is deactivated in current digiKam versions during runtime. The setting for this is in the collection settings. Otherwise, the metadata should be read in again via the item menu. And then we have the "Scan for new Items" in the Tools menu, which finds new and changed items, like the scan at the start.
