Defined In: https://spec.industrialontologies.org/ontology/core/Core/

Type: Object Property

Range: bfo.BFO_0000015 | bfo.BFO_0000202

Inverse Of: is temporally overlapped by

Definition

relation that holds between two intervals and processes i and j when the first instant of the temporal extent of i is earlier than and the last instant of the temporal extent of i is later than the first instant of the temporal extent of j, and the last instance of the temporal extent of i is earlier than the last instant of the temporal extent of j

Examples

  • When two plates are being welded at a joint, the cooling of a previously welded point temporally overlaps the heating of the point which is currently being welded; the sending process temporally overlaps the receiving process in a transaction process; Ancient Egyptian civilization (c. 3000 BCE - 30 BCE) temporally overlapped the Sumerian civilization (c. 3500 BCE - c. 2000 BCE) in Mesopotamia and the Indus Valley Civilization (c. 2600 BCE - c. 1900 BCE) in South Asia.

Semi-Formal Natural Language Axioms

LA1: If i β€˜temporally overlaps’ j then either both are β€˜temporal intervals’ or both are β€˜process’

LA2: If both i and j are β€˜temporal intervals’ and i β€˜temporally overlaps’ j then the β€˜first instant’ of j β€˜precedes’ the β€˜last instant of’ i and the β€˜first instant of’ i β€˜precedes’ the β€˜first instant’ of j and the β€˜last instant of’ i β€˜precedes’ the β€˜last instant of’ j

LA3: If both i and j are β€˜process’ and i β€˜temporally overlaps’ j then the β€˜temporal interval’ that i occupies β€˜temporally overlaps’ the β€˜temporal interval’ that j occupies

LA4: i β€˜temporally overlaps’ j if and only if there exists k that β€˜temporally finishes’ i and β€˜temporally starts’ j
