Are the examples provided sufficient justification?

The structured BM data (table Associated Person) says the physical object is somehow related to the script writer (who comes from a thesaurus). We cannot create a precise path involving FRBRoo because the relation is explaned in a mere note.

Sure there is: P67a_refers_to that's just like P67 but has physical domain.
We're currently doing:

<obj> P62_depicts <thes/people/Some-Actress>;
   P128_carries <obj/concept>.
<obj/concept> P67_refers_to <thes/people/Some-Script-Writer>.

We'd like to get rid of the parasitic (empty) node <obj/concept> and just do this:

<obj> P62_depicts <thes/people/Some-Actress>;
  P67a_refers_to <thes/people/Some-Script-Writer>.
