Get text of Dublin Core field

I’m trying to get the text of the field ‘Spatial Coverage’ (Dublin Core) of an public item.
Actually, I’ve got this:

$db = get_db();
$elementTable = $db->getTable(‘Element’);
$coverageElement = $elementTable->findByElementSetNameAndElementName(‘Dublin Core’, ‘Spatial Coverage’);
$item = $args[‘record’];

How can i do it?

Thank you very much.

You probably just want to use the metadata helper function. All you need is the $item:

metadata($item, array('Dublin Core', 'Spatial Coverage'))

It works!
Thank you so much!
I think I should have a look at the documentation to learn all functions…
