This seems sensible. I did have the idea of dumping a whole bunch of RDFa triples in the footer, and setting visibility to zero, but if you can do it safely in the head, problem solved! We're back to the old days of putting meta data in the head of a document. This works for the rel attribute, but what about for property? One nice thing about RDF is that it's a set, so if you put a full dump of triples in one area, even if there's a dup somewhere in your markup, a parser, should remove duplicates.
