Things and Interactions
The interactive semioverse introduces things as external handles and defines a calculus of interactions that generate semantic material.
Thing handles
A thing handle is a persistent name for a thing. It is not itself an element of the semantic domain; it is mapped into the domain by a seed function.
Interaction terms
Interaction terms are built from thing handles and definable operators. Their interpretation produces elements of the semantic domain.
Interaction surfaces
An interaction surface assigns a finite set of interaction terms to each thing. This surface is the interface used to build fragments for the thing.
