Resource Description Framework (RDF)

• based upon the idea of making statements about resources
• in the form of subject-predicate-object expressions, called triples
  -subject ->denotes the resource
  -predicate-> denotes traits or aspects of the resource and expresses a relationship between the subject and the object
• e.g. The sky has the color blue
  subject-> the sky
  predicate->has the color
  object->blue
• persisted in relational database or native representations also called Triple stores, or Quad stores if context (i.e. the named graph) is also persisted for each RDF triple
