We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame."],"metadata:def/prefLabel":{"@language":"en","@value":"occurrent"},"metadata:prefixIRI":"BFO:0000003","obo_purl:BFO_0000179":"occurrent","obo_purl:BFO_0000180":"Occurrent","obo_purl:IAO_0000600":{"@language":"en","@value":"An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region.
