Definition

Specification(s) of the location where an object (such as: a facility, instrument, or actor) exists, or where an event occurs.

Description

A location may be spatially localized as a zero-dimensional point or spatially extensive in one or more dimensions (for example: a curve, a surface, or a volume). An entity that consists of components with different locations (for example: the Great Lakes) may be characterized itself as having multiple distinct locations. An entity may have multiple specifications of its location(s) based on the quality and accuracy of each approximating representation.
