But this would probably requires some harmonization.
Even, I'm not convinced that a distinct EXIF domain is the best way to go. Non-default metadata domains are often not carried with images during translation or other processing and are (imho) more appropriate for data that would no longer apply to transformed imagery or that is bulky and of very limited interest. The EXIF metadata - at least the geolocation portions - is very relevant even after many kinds of transformation, is not too bulky and is very interesting to preserve. Instead i'd be inclined to identify the EXIF info as "well known" metadata names for the default domain.
