Definitions
BFO Definition
X is a role iff
X is a realizable entity
X exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be
X is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed

DOLCE Definition
X is a role iff X is an anti-rigid and founded concept, i.e.,
some instances of X may stop being instances of X
X’s definition involves (at least) another concept Y such that for each entity classified by X, there is an entity classified by Y which is external to it.
