Hello i can modify web?

hello again i want ask if i can delete this about dublin core

or modify

This is the description of the Dublin Core and this is not editable. You have three possibilities:

  • empty the description of the element set directly in the database (table “element_sets”;
  • create a plugin that uses the hook admin_items_form_tabs;
  • copy and modify the admin theme (file: admin/themes/default/items/form-tabs.php).
