E54 Dimension
This class comprises quantifiable properties that can be measured by some calibrated means and can be approximated by values, i.e. points or regions in a mathematical or conceptual space, such as natural or real numbers, RGB values etc.
E53 Place
This class comprises extents in space, in particular on the surface of the earth, in the pure sense of physics: independent from temporal phenomena and matter.
E52 Time-Span
This class comprises abstract temporal extents, in the sense of Galilean physics, having a beginning, an end and a duration.
E2 Temporal Entity
This class comprises all phenomena, such as the instances of E4 Periods, E5 Events and states, which happen over a limited extent in time.This extent in time must be contiguous, i.e., without gaps.
E92 Spacetime Volume
This class comprises 4 dimensional point sets (volumes) in physical spacetime regardless its true geometric form. They may derive their identity from being the extent of a material phenomenon or from being the interpretation of an expression defining an extent in spacetime.
