Sorry about the awful title. When I archive film negatives (positives) I would like to indicate the type of negative (135, 126, etc) and the roll number(my construction) and frame #. Any ideas other than using hierarchical keywords. Anything already in the standards XMP, IPTC, etc.
There is a FilmRollNumber tag, but unfortunately it is in the FlashPix metadata. :(
I would recommend creating some custom XMP tags.
