{
    $nap = new midcom_helper_nav();
    $current_leaf = $nap->get_current_leaf();
    if ($current_leaf)
    {
        $current_object = $nap->get_leaf($current_leaf);
    }
    else
    {
        $current_object = $nap->get_node($nap->get_current_node());
    }

    if ($current_object[MIDCOM_NAV_OBJECT]->parameter('midcom.helper.metadata', 'keywords'))
    {
        $midcom_site["metadata"]["keywords"] = $current_object[MIDCOM_NAV_OBJECT]->parameter('midcom.helper.metadata', 'keywords');
    }

    if ($current_object[MIDCOM_NAV_OBJECT]->parameter('midcom.helper.metadata', 'description'))
    {
        $midcom_site["metadata"]["description"] = $current_object[MIDCOM_NAV_OBJECT]->parameter('midcom.helper.metadata', 'description');
    }
