Just an FYI that I committed a MODS to RDF (my biblio vocab)
stylesheet. I wouldn’t call it done, but it works well enough for now.
In comparing the two representations, in the full (non-normalized)
form, the formats are about equally verbose (though mine is simpler I
think). When you take advantage of RDF normalization (treating Person
and Organization structures as basically like linked objects), mine is
much more compact. The stylesheet doesn’t do this normalization,
though; it’s not easy.
