comment: Comment: An instance of Site [snap:Site] is a mixture of independent continuant [snap:IndependentContinuant] entities which act as surrounding environments for other independent continuant [snap:IndependentContinuant] entities, most importantly for instances of object [snap:Object]. A site [snap:Site] is typically made of object [snap:Object] or fiat object part [snap:FiatObjectPart] entities and a surrounding medium in which is found an object [snap:Object] occupying the site [snap:Site]. Independent continuant [snap:IndependentContinuant] entities may be associated with others (which, then, are site [snap:Site] entities) through a relation of \"occupation\". That relation is connected to, but distinct from, the relation of spatial location. Site [snap:Site] entities are not to be confused with spatial region [snap:SpatialRegion] entities. In BFO, site [snap:Site] allows for a so-called relational view of space which is different from the view corresponding to the class spatial region [snap:SpatialRegion] (see the comment on this class).

comment: Comment: All instances of continuant [snap:Continuant] are spatial entities, that is, they enter in the relation of (spatial) location with spatial region [snap:SpatialRegion] entities. As a particular case, the exact spatial location of a spatial region [snap:SpatialRegion] is this region itself.
comment: Comment: An instance of spatial region [snap:SpatialRegion] is a part of space. All parts of space are spatial region [snap:SpatialRegion] entities and only spatial region [snap:SpatialRegion] entities are parts of space. Space is the entire extent of the spatial universe, a designated individual, which is thus itself a spatial region [snap:SpatialRegion].
comment: Comment: Space and spatial region [snap:SpatialRegion] entities are entities in their own rights which exist independently of any entities which can be located at them. This view of space is sometimes called \"absolutist\" or \"the container view\". In BFO, the class site [snap:Site] allows for a so-called relational view of space, that is to say, a view according to which spatiality is a matter of relative location between entities and not a matter of being tied to space. The bridge between these two views is secured through the fact that while instances of site [snap:Site] are not spatial region [snap:SpatialRegion] entities, they are nevertheless spatial entities.

comment: Comment: An instance of the spatiotemporal region [span:SpatiotemporalRegion] is a part of spacetime. All parts of spacetime are spatiotemporal region [span:SpatiotemporalRegion] entities and only spatiotemporal region [span:SpatiotemporalRegion] entities are parts of spacetime. In particular, neither spatial region [snap:SpatialRegion] entities nor temporal region [span:TemporalRegion] entities are in BFO parts of spacetime. Spacetime is the entire extent of the spatiotemporal universe, a designated individual, which is thus itself a spatiotemporal region [span:SpatiotemporalRegion]. Spacetime is among occurrents the analogous of space among continuant [snap:Continuant] entities.
comment: Comment: Spacetime and spatiotemporal region [span:SpatiotemporalRegion] entities are entities in their own rights which exist independently of any entities which can be located at them. This view of spacetime can be called \"absolutist\" or \"the container view\". In BFO, the class processual context [span:ProcessualContext] allows for a so-called relational view of spacetime, that is to say, a view according to which spatiotemporality is a matter of relative location between entities and not a matter of being tied to spacetime. In BFO, the bridge between these two views is secured through the fact that instances of processual context [span:ProcessualContext] are too spatiotemporal entities.
