Switch between Gwenview and Gthumb with metadata

I'm struggling a bit here...I've been using gthumb for a long time and I'm generally pleased with it. It started acting up some in Cinnamon though and works fine in KDE. Now I'm in KDE and a side effect is to try Gwenview again.

Yes, I can just stay with gthumb.

However....I'd like to try gwenview, but I don't want to spend hours/days re-tagging pictures from the last 4 years. The tags and comments aren't stored in the exif data, but rather in files alongside in each folder. I'm wondering if there is a way to share that data between Gwenview and GThumb. Google hasn't been any help...

Re: Switch between Gwenview and Gthumb with metadata

Bit more research...
Gwenview stores tags and comments in extended file attributes:

Semantic Information (rating, tags, description) added are stored in extended file system attributes. To list them, run attr -l file.jpg.

Gthumb stores everything in a .comments/imagename.xml format.

Not sure if I can write a script that will copy data from one to the other or not. I'll have to figure out how to read the extended attributes first!

Re: Switch between Gwenview and Gthumb with metadata

You can do it in a shell with getfattr / setfattr. The attributes used should be these.

tags: "user.xdg.tags", comma separated list of tags ("tag one,tag two,tag3")
rating: "user.baloo.rating", integer as string
description: "user.xdg.comment", simple text
