Why RDF?
• Granularity of description
• Flexibility of schema
• Extensibility of schema
• Re-usability and utilization of Linked Data
• Self-describing and can carry meaning
It’s not just machine readable; it’s machine actionable!
Skolemization
• Assigning a URI to a Blank Node

issues
2. Interested?
3. Come find me or other RDF aficionados
4. Breakout session today TBD to model out
solutions
5. Friday breakout session to work with RDF and
