    skos:definition "An anti-rigid, sortal role universal whose instances are borne by entities of a single substantial Kind and which borrows its identity from that bearer rather than supplying its own." ;
    rdfs:comment "UFO Role — anti-rigid, sortal role. An instance of a Role is borne by a bearer drawn from a single substantial Kind (e.g. Proprietor is borne by a Person — or by an Organisation under a named specialisation, but never simultaneously). A Role NEVER supplies its own identity; it borrows identity from its bearer (ODR-0005 Anti-pattern §3 — never key a Role). Per ODR-0006 §Q2." ;
    skos:scopeNote "UFO: Role (Guizzardi 2005 Ch. 4 §4.4 — anti-rigid, externally founded, sortal). Distinguished from RoleMixin by sortal commitment to a single Kind." ;
