Well... Unfortunately, this is not entirely true at the moment. They put the 

<meta property="og:title" content="Starbucks" />
<meta property="og:type" content="company" />
<meta property="og:url" content="http://www.facebook.com/Starbucks" />
<meta property="og:site_name" content="Facebook" />
<meta property="og:image" content="http://profile.ak.fbcdn.net/object2/1446/79/n22092443056_635.jpg" />


into their page header (using one of the examples David refers to in the google mail), put the 'og' prefix is nowhere defined in the file. That means that the current RDFa processors do not generate the intended triples...

:-(
