Code

function taxonomy_link($type, $node = NULL) {
  if ($type == 'taxonomy terms' && $node != NULL) {
    $links = array();
    if (array_key_exists('taxonomy', $node)) {
      foreach ($node->taxonomy as $term) {
        $links['taxonomy_term_' . $term->tid] = array(
          'title' => $term->name,
          'href' => taxonomy_term_path($term),
          'attributes' => array(
            'rel' => 'tag',
            'title' => strip_tags($term->description),
          ),
        );
      }
    }

    // We call this hook again because some modules and themes call taxonomy_link('taxonomy terms') directly
    foreach (module_implements('link_alter') as $module) {
      $function = $module . '_link_alter';
      $function($node, $links);
    }
    return $links;
