starts before the start of [P176] (P177): Difference between revisions

This property specifies that the temporal extent of the domain instance A of E2 Temporal Entity starts 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], 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, contains, finished-by}. This property is transitive. This property is asymmetric. Figure 14: Temporal entity A starts before the start of temporal entity B. Here A is longer than B Figure 15: Temporal entity A starts before
