Is there an easy to follow howto add rdf tags to drupal pages? In particular, I'm trying to add opengraph tags (http://ogp.me/). Wierdly, I find in D7 core one reference to what appears to be an opengraph tag. In profiles/standard/standard.install, there's some code... <code> 'mapping' => array( 'field_image' => array( 'predicates' => array('og:image', 'rdfs:seeAlso'), 'type' => 'rel', ), </code> ...as if it is trying to do exactly what I want, to add og:image data when a node contains an image field. Yet I can find no other code anywhere related to this. Any pointers appreciated. Thanks, -Dave
