Custom taxonomy - setting access based on role or capability

Question

I am only just learning about custom taxonomies for Wordpress. How is it possible to restrict access for my users to use a taxonomy. For instance, I have created a taxonomy

Answer 1

Would it be sufficient to remove the metabox from the Post Edit page? If so, give this a whirl:

function remove_featured_meta() {
   if (!current_user_can('moderate_comments')){
       remove_meta_box( 'featureddiv', 'post', 'side' );
   }
}

add_action( 'admin_menu' , 'remove_featured_meta' );

You can fill in the conditional statement with whichever appropriate capability corresponds to the user role to which you'd like to limit access to the taxonomy.
