Generally speaking, I like the blob of typed data + blob of arbitrary 
content, standard format metadata solution.
I tend to think that the best way to handle it is as two separate 
"files": /a.jpg and /a.jpg.meta or /a.jpg.meta.rdf or something.  Better 
to negotiate type on .meta and use .meta.rdf in situations without mime 
type negotiation.
