Good Morning, in my google webmaster center i have structured data problem in single page, gallerycategory and photogallery.

In single page i have solved adding this code :

function add_mod_hatom_data($content) {
 $iso8601_date = get_the_time('c');
 $author = get_the_author();
 $title = get_the_title();
 if( is_single() || is_page() ) {
$content .= '<div class="hatom-extra"><span class="entry-title">'.$title.'</span>
ultima modifica: <span class="updated"> '.$iso8601_date.'</span> 
da <span class="author vcard"><span class="fn">'.$author.'</span></span></div>';
 }
 return $content;
 }
add_filter('the_content', 'add_mod_hatom_data');

Now i can’t solved for galleryvategory and photogallery.
