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

Code

function rdf_help($path, $arg) {
  switch ($path) {
    case 'admin/help#rdf':
      $output = '';
      $output .= '<h3>' . t('About') . '</h3>';

This semantically enriched, machine-readable output for Drupal sites uses the <a href="@rdfa">RDFa specification</a> which allows RDF data to be embedded in HTML markup. Other modules can define mappings of their data to RDF terms, and the RDF module makes this RDF data available to the theme. The core Drupal modules define RDF mappings for their data model, and the core Drupal themes output this RDF metadata information along with the human-readable visual information.
