EXIF is specific to JPEG files, but you find almost the same
information in the TIFF/EP format. So we should try to have a generic
solution for the GIMP, that is not limited to EXIF only. If you look
at bug #56443 and have a look at the proposal for adding EXIF support
to the PNG file format (http://pmt.sourceforge.net/exif/index.html),
you will see a long table that describes how the individual fields can
be mapped from one file format to the other.
That's why I wrote in my previous mail that all data should be saved
in GIMP parasites, because that would allow each file plug-in to
import/export the parts that are appropriate and discard or convert
the rest. So we should be able to have something like this:
Load JPEG/EXIF file -> GIMP parasites -> Save TIFF/EP file
