RDF/A Embedding RDF in HTML

A draft has been published of RDF/A.

This is a really simple way to embed RDF into html. Example:

<html>
    <head>
        <title>Jo Lambda's Home Page</title>
    </head>
<body>
<p>
 Hello. This is <span property="foaf:name">Jo Lambda</span>'s
home page.
 <h2>Work</h2>
 If you want to contact me at work, you can
 either <a rel="foaf:mbox" href="mailto:jo.lambda@example.org">email
 me</a>, or call <span property="foaf:phone">+1 777 888 9999</span>.
 </p>
</body>
</html>
