right, so sioc:User it is.

By the way, on http://drupalrdf.openspring.net/node/3 the sioc:reply_of

agreed. that's what I explained at [1] and that's due to Drupal internals.
We're working on a solution which will in fact move the property attribute
one level down on a new tag which will wrap the content. That way the
property attribute will be on a tag at the same level (sibling) as
       <span rel="sioc:reply_of" resource="/node/3" />

that should in theory work and produce the intended RDFa...

Steph.
