I’ve built a sample post [1], using Facebook Notes, to see if I can embed structured data using nanotation. My experiement worked:

To conclude, you can use RDF-Turtle or JSON-LD to inject structured data (I only used RDF-Turtle because I find it easier to write). That said, if Facebook adopted the tweaks you’ve requested life will be much easier for everyone :)
