The following are the main points you should have learned from this chapter:

  • Individual–property–value triples form a flexible, universal representation for relations.

  • Ontologies allow for semantic interoperability and knowledge sharing.

  • OWL ontologies are built from individuals, classes, and properties. A class is a set of real and potential individuals.

  • A top-level ontology allows for a framework where domain ontologies can be designed to interoperate.

  • Data repositories with provenance, based on ontologies, are widely used in modern data-driven science.
