Domain:

crm:E2 Temporal Entity

Range:

crm:E2 Temporal Entity

Quantification:

0,n:0,n

Subproperty of:

• crm:E2 Temporal Entity → crm:P182 ends before or with the start of (starts after or with the end of) → crm:E2 Temporal Entity

Scope note:

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.

Examples:

Gisle taking office as Bishop of Linköping 1139 AD (E7) ends before the start of The Guta saga composition (E65). (Peel, 1999)

Troy VII (E4) ends before the start of Troy VIII (E4). [uninhabited for some 200 years]

The use of the Tomb Four from Nikitopoulou group in Nihoria in the MHIII-LHI period (E4) ends before the start of the period of reuse of the Tomb Four from Nikitopoulou group in LHIIIA (E4). [“Of the six tombs excavated in the Nikitopoulou group […] the finds in Tomb Four are of MH II or MH III-LH I date, with the exception of the finds with the Northern group of material, which is uniformly dated to LHIIA2, end the ewer in the middle of the floor, dated LHIIIA1. […] The preserved evidence seems clearly to indicate use in the MHIII-LHI use in the MHIII-LHI period followed by a period of reuse in LHIIIA, a pattern matched at architecturally similar sites such as 13:Kaminia and 10:Gouvalári”] (Boyd, 2002)

In First Order Logic:

• P183(x,y) ⇒ E2(x)
• P183(x,y) ⇒ E2(y)
• P183(x,y) ⇒ P182(x,y)
