Has anyone else run into this, and is there a solution?
In earlier versions of Darktable, when I exported an image, it would include both the hierarchical and non-hierarchical tags in the metadata information.
For example, here’s a couple of the relevant metadata lines from exitftool for a pre-3.0 exported image:
Subject : Aerial, Image type, Photo specs, Transportation, airplane, public transport
Hierarchical Subject : Photo specs|Image type|Aerial, Transportation|public transport|airplane
Now, with Darktable 3.0, I’m only getting the tags in Subject but the Hierarchical Subject is gone.
That’s put a massive roadblock in my workflow.
That’s because I preface tags with different categories (Species, Person, iNaturalist field, etc.) and use a bash script to strip off or simplify tags before exporting images to the internet. For example, I’d remove “Person|Jane Doe”, and all other people’s names, from images before uploading to Flickr.
This is now impossible(/annoyingly difficult) to automate and I’m scratching my head wondering what to do.
If there’s a workaround or a fix to get the Hierarchical Subject back in my exports, I’d love to hear about it. I’m not seeing anything in the Darktable preferences.
