Open Graph Protocol: is currently being consumed by Facebook (see their documentation) and is being published by IMDb, Microsoft, NHL, Posterous, Rotten Tomoatoes, TIME, Yelp, and others.

Dang, I’m so busy with work I don’t have time to post much here these days, even though I feel another library lament coming on. Perhaps it’s best for all I don’t. Maybe I should do something that’s at least related to work; that way I can vaguely...
The meta tags are intentional; they come from the RDFa syntax spec ([link]). We’re not exactly using the tags as intended by the Semantic Web community, but think that it’s the right balance between developer simplicity and standards.

The meta data employed by the open graph protocol complies with RDFa syntax and the corresponding DOCTYPE was supposed to be “XHTML + RDFa”. However, even you use this DOCTYPE, you will still get errors (less than before) because “XHTML + RDFa” needs the Web page be be an XHTML page in which tags like <iframe> are not recommended any more and attributes like @alt in <img> become compulsory. So the thing is this protocol does not require that the more strict syntax XHTML should be used. Hopefully, one day there will be a trade-off.
