I started doing this in XnView (and Shotwell) but it’s hard to commit the time to sit down at the desk in front of the computer when I’ve always got the tablet/phone around me.

I would love it if F-Stop could support nested tags, so I could keep the same structure I’m already trying to use.

I’m not sure if there’s a standard for separating levels in the hierarchy though. I think the digikam folks did an analysis of different implementations.

I also think there’s another post in the forum with the same request, but I can’t find it right now.
