- An ontology is often best expressed using triples: subject-predicate-object.
- An ontology can be handwritten or drawn (as a diagram) for the benefit of humans.
- An ontology has to use a schema — a formal system of technical notation — so that it can be understood by computers.
- There are two broad types of schemas: database schemas and XML schemas.
- A schema codifies an ontology. The schema is then applied to actual data in order to codify the data in line with the ontology.
