Deactivate Dublin Core tab

For a client I like to build a website using Omeka.
Since the client isn't going to use the Dublin Core fields at all (just custom Itemtype metadata) I want to get rid of the Dublin Core fields/ tab on the dashboard.
I'm searching through the forum, but could only find ways to remove the fields/ name from website front. But since I'm affraid it would confuse my client when updating the website, I like to remove it from the dashboard aswell.

Any leads?

Pretty much the best way to do this is with a plugin, you can filter on admin_items_form_tabs and remove or reorder the tabs as you wish.
