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: http://bugzilla.gnome.org/show_bug.cgi?id=61499 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.
