I also use darktable, but not for tagging, only for rating.
All existing tags are set with digikam version 4.x

Might be, but why can I remove tags in digikam and they turn up again, 
when maintenance writes from files to database.
If they cannot be deleted by digikam, then it should not be possible to 
untag them with digikam in the first place.

I did a test with digikam, making sure the database and files tags (all 
writeable) are the same. I emptied and deleted the tags, then I deleted 
the database and the .xmps - then maintenance files to database - tags 
return(!).

I probably need some exiftool magic to get rid of unwanted tags.

The most efficient wiping ist "deleting database" and that I did, 
without success.
I miss an option: "remove all tags digikam can see".
