Hi Jean Francois,
The schema is defined as well in Exiv2. I do it personalty.
An ordered list sound logical for me. Why un-ordered one ?
The digiKam schema is a private stuff. If a 3rd party don't play properly
with it, this is not digiKam fault. As you said : "Other software
(exiftool, the Gimp) process as an unordered list, a <rdf:Bag>."
Why this software do not respect how digiKam store metadata ?
