Yes, that is the intended behaviour. There doesn't seem to be a real standard way of storing hierarchical keywords that is widely supported. Because of that Adobe created their own "hierarchicalSubject" field which we use, too. In order to stay compatible with other programs that don't support that field we also put keywords into the "subject" field and follow Adobe's lead of adding all the intermediate parts of the keyword, too. It seems that behaviour can be configured in (at least) Lightroom to only add the leaf nodes. Maybe we can add such an option. When reading XMP files we ignore "subject" when "hierarchicalSubject" is also present. While that might lead to missing tags if the XMP was edited with a program that only supports "subject" it still seems like a better way than importing everything. Maybe Digikam should do the same? > I'm on Darktable 2.2.5 > > Cheers > Matthias Tobias
