Hello,
I like Danielle's idea. I wonder if it wouldn't be a good idea to decouple
the metadata from the data permanently. Exiftool allows you to export the
metadata in lots of different formats like JSON. You could export the
metadata into JSON, run the checksums and then store the photo and
Also just stumbled across this on stackoverflow.

Kyle,
It's a bit of a hack, but you could write a script to delete all the
metadata from images with ExifTool and then run checksums on the resulting
image (see http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=4902.0).
exiv2 might also work. I don't think you'd want to do that every time

Kyle,
I think I can answer your question, but I would need to know a little bit
more about what you're doing before attempting to help: how are you
packaging up your objects, how are you storing the content, and how are you
generating checksums. Even more specific than that:

Howdy all,
I've been toying with the idea of embedding DOI's in all our digital assets
and possibly inserting/updating other metadata as well. However, doing this
would alter checksums created using normal methods.
Is there a practical/easy way to checksum only the objects themselves
without the
