  • The Semantic WebPrinciples Building blocks are very simple! Describing resources with Resource Description Framework Subject the resource being described Property denotes traits or aspects of a resource Object the associated resource Chasing Serendipity with Linked Open Data Rob Stewart, Jamie Forth & Diana Bental 10 / 32
  • The Semantic WebPrinciples Building blocks are very simple! Describing resources with Resource Description Framework Subject the resource being described Property denotes traits or aspects of a resource Object the associated resource e.g. <Joe Bloggs> age "40" <Joe Bloggs> friend <Harry Hill> <Hary Hill> location <Edinburgh> Chasing Serendipity with Linked Open Data Rob Stewart, Jamie Forth & Diana Bental 10 / 32
