Warning, one important part cannot be found in XMP : Exif makernotes. This is a
huge problem there, because these private data cannot be translate to user
readable xmp tags.

My proposal with Andreas Huggel (Exiv2 author, available in this room), is to
set a single XMP tag to host whole binary Exif makernote tag content as well.
He is not very convinced by this way, but at least, we not lost any import
camera maker data in XMP.

Look like ExifTool do something like that :


... search "Markernote" section...
