I have been using Darktable sporadically for a while now since I decided not to pay for Lightroom anymore. Now I just noticed that some of the tags are duplicated. Back in Lightroom I organized the people tags like this
Person John Smith Jane Smith ...
Now in Darktable, I seem to have every single person twice. Once in the Person category, and once without category.
John Smith Jane Smith Person John Smith Jane Smith
Since I didn’t notice this from the beginning, those tags are now diverged. So I can not just delete all person tags not in the person category. Is there a way I can merge them? When I try to move the John Smith tag into the Person category I get the message: “at least one new tagname (Person|John Smith) already exists, aborting.”
After writing this, I found the “rename-tags” script in Darktable, which allows you to merge two tags. But since I have around one hundred person tags, this will take a while.
