Change: RDF Data Model

The RDF Data Model (RDF Model) is closely connected with the Model of Relation Databases. A Relation Database consists of Tables, which consists of Records (Rows). Each Record consists of a Set of Fields. The Record is nothing but the Content of its Fields, just as an RDF node is nothing but its Connections: the Property Values.

RDBMS Elements can therefore easily be mapped to their Counterparts in RDF:

  • record (row) -> Node (Subject)
  • Field (Column) -> Property
  • Record Field (Table Cell) -> Value (Object)
  • Primary key -> URI of the node
