That's a somewhat simplistic view of an ontology. What you described matches
the definition of a taxonomy, which is considered one of the "simplest
ontology" sorts available.
An ontology is a formal definition of your concepts, terms and rules of your
modeled world. Languages to describe an ontology like OWL help enforce
business rules for instance.
