I’m looking for an image metadata manipulation library, and so far I’ve  
only found a couple that look usable. ruby-exiv2 uses the C++ exiv2  
library, but is incomplete (no xmp support, doesn’t seem to handle  
multiple iptc keywords. mini-exiftool uses the excellent exiftool  
library,  
but that’s written in Perl, and I’d rather use something that’s either  
pure-ruby, or a C/C++ library for efficiency.

Does anyone know of any mature image metadata manipulation libraries  
that  
I’ve missed?

Paul

EXIFR, which is pointed to in the above link, is EXIF only. I’m looking  
for something that does IPTC and XMP.
