Ontology is the standardization of meanings
 (i.e., terms and concepts of a
 language)
 An Ontology models the meaning (semantics) of a Domain(s)
 Ontology thus includes:
 Objects (things) in the many domains of interest
 The relationships between those things
 The properties (and property values) of those things
 The functions
 and processes involving those things
 Constraints
 on and rules about those things
