Enables semantically enriched output for Drupal sites in the form of RDFa.

Code

function rdf_preprocess_image(&$variables) {
  // Adds the RDF type for image.  We cannot use the usual entity-based mapping
  // to get 'foaf:Image' because image does not have its own entity type or
  // bundle.
  $variables['attributes']['typeof'] = array('foaf:Image');
