I agree with Jasper's suggested approach, this is also what I meant with
"put the roles on Product as properties"
Product{
$owners;
$manufacturers;
}
In case you expect the roles to change a lot, you can have a look at the
PartyRelationship and PartRole pattern, but this is probably overkill for
your use case ;)
Cheers!
