I can't seem to find the answer to this.
Is it possible to have the "Identifier" element display in the search results/browse lists?
The identifier is something that is often used by the folks who would be using this system, and I'd like folks to see it before they click on a specific item.
This can be done with a small change to your theme's item/browse.php file. If it doesn't have that file, create the item directory and copy browse.php from the {Omeka-Root}/application/views/scripts/items directory.
Adding the following code will display the identifier
<?php echo item('Dublin Core', 'Identifier'); ?>
