I have your repo starred from a post/comment you made a few weeks ago but haven't had time to actually use/integrate it with my own stuff.
What are your thoughts on XMP sidecar files? I'm torn right now between digital negative + external metadata versus all-in-one image with mutable properties. Portability vs. Durability etc.
I've avoided using XMP sidecars. Mostly because I don't want to have to worry about two files for every photo. And I don't think they're ubiquitously supported like EXIF.
Thanks for starring the repo and let me know if you need any help.
