As a picture is worth a thousand words, I built a mockup based on the
GIMP metadata editor. The Exif tab has been left alone as a lot of
that data comes straight from the camera. The XMP and IPTC tabs have
been merged and separated into tabs called: Who, What, Where, When
according to Metadata Working Group guidelines.
Under the hood, gexiv2 composite functions would be used to read and
write to the correct metadata fields.
