Definition
A temporal entity consisting of change over time (whether extended or instantaneous) involving (simple or complex) interaction(s) of physical entities and which may have geometric position and extent.
Description
An event involves one or more changes in physical entity(ies). An event has temporal properties (for example: date(s) and duration) and may have temporal parts. An instantaneous event is the limit case (in time). Temporal properties are used to describe the duration of an event in time; for example, specified date(s) of a calendar time period and/or a specified duration of the event. An event may have point (instantaneous) or interval (extended) duration. Events may have temporal parts (which are also events). Temporal parts of an event may be sequential (for example: the sequential innings of a baseball game) or concurrent (for example: sub-events of a complex event, which are occurring at the same time, such as voting activities at many separate polling places during a national election). Events may be long-duration processes (for example: the construction of Hoover Dam), with continuous or discontinuous activity, or discrete events which have continuous activity bounded by definite date-times, whether known or unknown (for example: running the Boston Marathon; the lifetime of Alexander the Great). An event may have geometric position and extent based on the location(s) where the interactions occur and the spatial extent of the actors and effects involved.
