This property specifies that the temporal extent of the domain instance A of E2 Temporal Entity ends definitely before the start 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 < Bstart is true.
This property is part of the set of temporal primitives P173 – P176, P182 – P185.
This property corresponds to the following Allen temporal relation (Allen, 1983) : {before}.
This property is transitive.
