EXIF data category of "Film"

Does anyone know why my posted photos almost always show "JPEG" (digital) rather than "RAW", in which I shoot all my photos? The fact that the odd time "Raw" appears leads me to believe there may be a flaw in the pipeline somewhere other than on my end. Of course I realize my Raws all get turned into jpegs when I export them from LR, otherwise ZINE can't publish them, but still.......?
