rdf_process
function rdf_process
rdf_process(&$variables, $hook)
Template process function for adding extra tags to hold RDFa attributes.
Since template files already have built-in support for $attributes, $title_attributes, and $content_attributes, and field templates have support for $item_attributes, we try to leverage those as much as possible. However, in some cases additional attributes are needed not covered by these. We deal with those here.

- Enables semantically enriched output for Drupal sites in the form of RDFa.
Code
function rdf_process(&$variables, $hook) { // Handles attributes needed for content not covered by title, content, // and field items. It does this by adjusting the variable sent to the // template so that the template doesn't have to worry about it. See // theme_rdf_template_variable_wrapper(). if (!empty($variables['rdf_template_variable_attributes_array'])) { foreach ($variables['rdf_template_variable_attributes_array'] as $variable_name => $attributes) { $context = array( 'hook' => $hook, 'variable_name' => $variable_name, 'variables' => $variables, ); $variables[$variable_name] = theme('rdf_template_variable_wrapper', array('content' => $variables[$variable_name], 'attributes' => $attributes, 'context' => $context)); } } // Handles additional attributes about a template entity that for RDF parsing // reasons, can't be placed into that template's $attributes variable. This // is "meta" information that is related to particular content, so render it // close to that content. if (!empty($variables['rdf_metadata_attributes_array'])) { if (!isset($variables['content']['#prefix'])) { $variables['content']['#prefix'] = ''; } $variables['content']['#prefix'] = theme('rdf_metadata', array('metadata' => $variables['rdf_metadata_attributes_array'])) . $variables['content']['#prefix']; } }
