gexiv2 is a GObject wrapper around the Exiv2 photo metadata library. It allows for GNOME applications to easily inspect and update EXIF, IPTC, and XMP metadata in photo and video files of various formats.
The Yorba Foundation inherited the initial gexiv2 code from Mike Gemuende (his initial repository is here).
gexiv 0.10.3 released on March 23, 2015.
GIMP has chosen Exiv2 (via gexiv2) for metadata support!
Thanks to GObject Introspection support added in 0.5, gexiv2 now has excellent bindings for Python 2 & 3 available.
