This property specifies that the temporal extent of the domain instance A of E2 Temporal Entity ends definitely before the end of the temporal extent of the range instance B of E2 Temporal Entity.
In other words, if A = [Astart, Aend] and B = [Bstart, Bend], we mean Aend < Bend is true.
This property is part of the set of temporal primitives P173 – P176, P182 – P185.
This property corresponds to a disjunction (logical OR) of the following Allen temporal relations (Allen, 1983): {before, meets, overlaps, starts, during}.
This property is transitive.
