Code

function rdf_comment_storage_load($comments) {
  foreach ($comments as $comment) {

    // Pages with many comments can show poor performance. This information
    // isn't needed until rdf_preprocess_comment() is called, but set it here
    // to optimize performance for websites that implement an entity cache.
    $created_mapping = rdf_get_mapping('comment', $comment

      ->getPreparedFieldMapping('created');

      // The current function is a storage level hook, so avoid to bubble
      // bubbleable metadata, because it can be outside of a render context.
