I don't think the RDF does meta tag data, you have to add those yourself. It seems something more for a project like <a href="http://drupal.org/project/metatags">http://drupal.org/project/metatags</a> to support (and is planned). Alos <meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://drupal.org/project/opengraph_meta">http://drupal.org/project/opengraph_meta</a> works right now.<div>

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