I am quite familiar with Dublin Core because a part of my work
involves dealing with "semantic web" and other funny things like
CC/PP, UAProf, UDDI, WSDL, ...  But this is a solution to the wrong
problem.  My goal is not to invent new ways to organize the metadata.
I simply want to be able to parse, modify and save the metadata that
is already defined in some standards such as EXIF and TIFF/EP.

If recommend that you have a quick look at the document describing how
EXIF data could be stored in PNG files.  This document is available
from http://pmt.sourceforge.net/exif/drafts/d020.html.  It already
contains a long list of tags that should be supported.

Nice to know...  ;-)

This is exactly what is proposed in bug #61499.  Take a look at this:
See also bug #65181, which includes a small screenshot from PSP.
It would be nice to have a plug-in that attaches itself to the menu
entry <Image>->File->Properties and allows the user to view and edit
the metadata in a user-friendly way.
