Coming from the thread How to hide or move out some keywords I would like to understand how Mylio uses and updates the metadata in image files and XMP sidecar files.
If XMP data and metadata in the image file (EXIF) differ, what is the ground truth Mylio reads from?
And when Mylio updates the metadata, does it write to both?
I ask this because I want to read and write metadata outside of Mylio and need to know what files to target.
Thanks for clarification!
