RDF in programming practice

• For example, using Java+Jena (HP’s Bristol Lab):

• • a “Model” object is created
  • the RDF file is parsed and results stored in the Model
  • the Model offers methods to retrieve:
  • • triples
    • (property,object) pairs for a specific subject
    • (subject,property) pairs for specific object
    • etc.
  • the rest is conventional programming…

• Similar tools exist in Python, PHP, etc. (see later)
