  17. 17. It’s built using: Resource Description Framework (RDF)@prefix : <http://www.example.org/> .:john a :Person .:john :hasMother :susan .:john :hasFather :richard .:richard :hasBrother :luke .• More info http://en.wikipedia.org/wiki/Resource_Descrip tion_Framework
  18. 18. Its something to think about for your project• Include RDF for your data• Your relational database is a simple example ▫ UserA follows UserB ▫ UserA is from Ireland ▫ UserD loves a film: The Notebook
