This is a bit off topic, but I find this iptc/xmp very confusing 
sometimes. In Digikam they both show about the same fields (under 'edit 
all metadata'), but which one to use? Is one of them enough?
It would be easier if everything could be done through the panel on the 
right, instead of two places.
