Chains of object properties

Composition and derived relationships (OP composition)

Knowledge subjects connect through chains of object properties. Following a chain ◊R₁ ∘ ◊R₂ ∘ … yields derived relationships without storing every shortcut explicitly—e.g. kinship shortcuts such as “aunt” from “mother” and “sister”. The canonical section on OP composition also discusses kinship and social relations; [ArSm2015] notes optional roles.

[GuAl2015] analyses relators and powertypes in such settings; [AlHe2020] covers OWL property chains where applicable.

This page extends Relators: relator individuals can mediate the same facts that chains summarize, depending on modeling style.
