Alan Ruttenberg: This is a binary version of a ternary time-indexed, instance level, relation. The BFO reading of the binary relation 'has participant at some time@en' is: exists t, exists_at(x,t) & exists_at(y,t) & 'has participant@en'(x,y,t)

BFO2 Reference: independent continuant that is not a spatial region, specifically dependent continuant, generically dependent continuant
has_participant is an instance-level relation between a process, a continuant, and a temporal region at which the continuant participates in some way in the process. (axiom label in BFO2 Reference: [086-003])
if b has_participant c at t & c is a generically dependent continuant, then there is some independent continuant that is not a spatial region d, and which is such that c g-depends on d at t & b s-depends_on d at t. (axiom label in BFO2 Reference: [091-003])
if b has_participant c at t & c is a specifically dependent continuant, then there is some independent continuant that is not a spatial region d, c s-depends_on d at t & b s-depends_on d at t. (axiom label in BFO2 Reference: [090-003])
if b has_participant c at t then b is an occurrent. (axiom label in BFO2 Reference: [087-001])
if b has_participant c at t then c exists at t. (axiom label in BFO2 Reference: [089-001])
if b has_participant c at t then c is a continuant. (axiom label in BFO2 Reference: [088-001])
