Briefly, What is it?

OT is a method of managing information that closely reflects the real world. As humans, we view real word entities (or objects) and events in 2 ways:
 

1. Facts about entities and events (Episodic)
   • for example, my cat's name is Jess.
2. Their universal principles (Semantics)
   • cats are animals.

Humans then use language to describe these 2 types of views:
 

1. The set of all things to which an entity applies (Extensions)
   • for example, my neighbour's cat is Biggles, John's cat is Tiddles, etc. etc.
2. The definition of the entity which can include its behaviour (Intention)
   • a cat is a small carnivorous, warm-blooded, furry animal .......

Often when we define new entities and events we will relate them to previous know items or situations. We can do this in 2 ways:
 

1. By constructing new objects from existing smaller components
   • for example, a new car uses the same carburetor as an existing model, and the carburetor in turn is made of pre-existing nuts and bolts.
2. By relating new objects to pre-existing conditions or situations
   • the new car must conform to the existing conditions for road vehicles.
