- 12. What is RDF?
- 13. RDF is a model predicate subject object
- 14. Is that it?
- 15. Yes, that’s it. predicate subject object
- 16. The model can be serialized as XML

- 18. The model can be serialized as XML It’s pig ugly That’s fine. Machines eat ugly for breakfast
- 19. Honestly, don’t worry RDF != RDF/XML
- 20. Our model can describe models

- 22. Specific Models About stuff
- 23. Specific Models About Things
- 24. Specific Models About Things Let’s call these ontologies

- 28. Ontologies are described in OWL OWL is modeled in RDF
- 29. RDF is machine readable
- 30. RDF is machine readable So ontologies can understood by machines
