The core Ontology for production related concepts (Product, Process, Resource). It provides
2 ubiquitous aspects: hierarchical structure and type-instance relationship.
An Entity is an object in the application domain. A SubEntity represents a child in the 
hierarchical structure. A Definition represents a type in the type-instance relationship.

The following concepts are formalized:
- an **Entity** is an instance
- a **Definition** is information common to a set of instances
- a **SubEntity** is a (reified) reference to a child of the Entity

The ontology supports 2 transversal aspects
- **hierarchy** (or parent-child relationship):
  - things (elements) are composed of sub-things (sub-elements)
- **definition** (or type instance relationship):
  - things (entities) are defined by other things (definitions)

Hiearchy can be for instance:
- for a Product, its parts, which are typically reified relations to other (sub) Products
- for a Process, its steps, which are typically reified relations to other (sub) Processes

Definitions can be for instance:
- for a Product, its design, or its make
- for a Product with variability, values for the variation points
- for a Process excution, a reusable description of the things to be performed."""@en ;
