Expression and tight incorporation of the following properties

1. Perspective
   1. Magnitude
      1. Represents the Intent of the Perspective.
   2. Direction
      1. Represents the direction the Perspective is facing in spacetime.
         1. Implemented as a point outside of the Subject in 4 dimensional spacetime, the direction is the straight line in 4 dimensional spacetime connecting the Subject’s location in 4 dimensional spacetime to the point described above.

The reason that this is the foundational value is that Perspectivity emerged from Perspectivity as Physics. Since everything emerged from that concept during formulation, and because I have ambition to at least try to formulate new science, the primary intent of Perspectivity as a Domain is to be able to describe a 5 dimensional PerspectivitySpace that can be used to formalize and test Perspectivity as Physics.
