object_boundaryc back to ToC or Class ToC

IRI: http://www.ifomis.org/bfo/1.0/snap#ObjectBoundary

Comment: Boundaries are theoretically difficult entities to account for, however the intuitive notion of a physical boundary as a surface of some sort (whether inside or outside of a thing) will generally serve as a good guide for the use of this universal.

IRI: http://www.ifomis.org/bfo/1.0/snap#Site

Comment: Site [snap:Site] entities should not be confused with spatial region [snap:SpatialRegion] entities.

is disjoint with

spatiotemporal_intervalc back to ToC or Class ToC

IRI: http://www.ifomis.org/bfo/1.0/span#SpatiotemporalInterval

connected_spatiotemporal_regionc
is disjoint with
spatiotemporal_instantc

spatiotemporal_regionc back to ToC or Class ToC

IRI: http://www.ifomis.org/bfo/1.0/span#SpatiotemporalRegion

Comment: This is the time and space within which occurrent [span:Occurrent] entities exist. Occurrent [span:Occurrent] entities exist in space and time in a different way from that in which continuant [span:Continuant] entities do and thus the space and time in which they exist is itself different. The importance of spatiotemporal region [span:SpatiotemporalRegion] is primarily theoretical and it will not be used often in most domain ontology applications.

temporal_instantc

temporal_regionc back to ToC or Class ToC

IRI: http://www.ifomis.org/bfo/1.0/span#TemporalRegion

Comment: This is the time that is common to both SNAP and SPAN entities. The time of temporal region [span:TemporalRegion] and its sub-classes will normally be the time that should be referred to when sub-classing universals having to do with time in an ontology.
is equivalent to
connected_temporal_regionc or scattered_temporal_regionc
has super-classes

connected_temporal_regionc, scattered_temporal_regionc
