Custom Taxonomy user based creation

Re,

I think i figure out this topic.

To create a user based Term in Custom Taxonomy, i’ve created a meta attached to the term (new WP 4.4 feature) ‘author’ which contains the logged in user ID :

add_term_meta($term_id,'author',get_current_user_id());

and then to retrieve the user who has created the term :

$author = get_the_author_meta( 'user_nicename', intval(get_term_meta($term_id,'author')) );

I think it’s the best way to do it.

cheers !
