Structure. Networks of meaning interconnection that create coherence in text, image, space, object, body, sound, and speech. In a functional sense, structure is realized in systems that can be characterized by their ontology or connections in the universe to which they refer, their explicit and implicit internal relations, their designs, and the relations in their ordering.
