Todo

FIXME: The following are broke: SubjectArea. Need to test the more obscure tags. DigitalZoomRatio = 0/0 is rejected. need to determine if that's valid. Possibly should treat 0/0 = 0. need to read exif spec on that.

The version of the output format

Before the actual metadata information is saved in the database we strip some of it since we don't want to save things like thumbnails which usually accompany Exif data. This value gets saved in the database along with the actual Exif data, and if the version in the database doesn't equal the value returned by this function the Exif data is regenerated.

Returns

int
