I'm currently using <?php echo show_item_metadata( array('show_empty_elements' => false) ); ?>
to prevent empty fields from displaying. Also I've added a conditional statement to the item-metadata.php to prevent a few other metadata fields from displaying even if they have data in them.
However, I noticed in the newer themes like Berlin 1.3 you can customize the Dublin Core fields for display in the admin mode. Currently I'm using a very modified Emiglio theme. Is there a way to revise my theme so that I can configure it from the admin mode? Or is there a way to put my theme into a 1.3 theme? I've looked into modifying the Berlin theme, but there doesn't seem to be the same files I'm used to seeing (screen.css index.php, browse.php), so I'm not sure what to edit.
