Just as an experiment (because I'm trying to figure out how to better
rationalize my own metadata), and FWIW, I thought I'd see what it
would take to make this MADS example ...
... valid RDF: Here it is:
<!-- the below relation is pretty meaningless of course -->
Am not sure the details are quite right, but it's less verbose than
the pure xml version, and almost everything is now a uri resource.
Because it relies more on elements, it's also more easy-to-handle xml
(an old mantra of mine). And, of course, that doesn't include
whatever else might come along with RDF.
