This property specifies that the temporal extent of the domain instance A of E2 Temporal Entity starts before or simultaneously with 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], it means A-start ≤ B-start 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, started-by, contains, finished-by, equals} In a model with fuzzy borders, this property will not be transitive. This property is irreflexive. Figure 12: Temporal entity A starts before or with the start of
