Class: Perspective
A Perspective represents subjective meaning, encoded through associations between expressions, a.k.a. Links, that is a graph over the objective Expressions of any subset of Languages.
This type represents the clean onotological concept of a Perspective. An instance of this class can be regarded as an immutable snapshot of a mutable perspective.
The types PerspectiveProxy and PerspectiveHandle are used when dealing with an instantiated mutable perspective as is done through most of the GraphQL mutations.
