first person in the tie - for a directional type (Minister, Advisor, Courtier, Patron) this is the one in the subordinate/serving role; for a symmetric one (Ally, Rival) order doesn't matter

second person in the tie - for a directional type this is the one being served

the kind of non-family tie a GanjoorPersonAffiliation represents between two people - e.g. a minister serving a king, an advisor, a patron. Unlike PersonRelationType this has nothing to do with kinship; it's what lets two otherwise unrelated family trees show up as adjacent (e.g. "some Barmakids served the Abbasid court") without merging them into one tree. New values can be appended safely later (stored as int) as more cases come up.
