While looking around for things dealing with this thread, I happened
upon exiv2[1], which is an Exif and IPTC tag reader/writer.  And as it
turns out there are ruby bindings to it already.  You can use macports
to install the original library and then use gem to install the ruby
bindings[2] to it.  The documentation is a little lacking for the ruby
bindings, but it is quite fun too play around with.  I'm already
thinking of a few uses for it.

enjoy,
