How can I set a relationship between two taxonomy terms (each of a different taxonomy)?
So, relate a "person" term "John Doe" with a "company" term "Acme Inc"?
Wow, it just works... I can use wp_set_object_terms() to set a term to a term...
$term_taxonomy_ids = wp_set_object_terms( $bill_term_id, $microsoft_term_id, 'company' );
And I can retrieve the company connected to a person with wp_get_object_terms like...
$bills_company_terms = wp_get_object_terms($bill_term_id, 'company');
The only thing is, how can I put a backend interface on these relationships?

Alas, it appears not to be bidirectional. When I wp_get_object_terms() for the company, it does not seem to contain the person which had related the company to itself. – Robert Andrews May 9 '20 at 21:21
