Scope note

Text

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 = [A^start, A^end] and B = [B^start, B^end], we mean A^end < B^start 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. This property is asymmetric.
