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

b occupies_spatial_region r at t means that r is a spatial region in which independent continuant b is exactly located (axiom label in BFO2 Reference: [041-002])
every region r is occupies_spatial_region r at all times. (axiom label in BFO2 Reference: [042-002])
if b occupies_spatial_region r at t & b continuant_part_of b at t, then there is some r which is continuant_part_of r at t such that b occupies_spatial_region r at t. (axiom label in BFO2 Reference: [043-001])
