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,
