RDF(S) in Practice
Jena (cont)

But Jena is much more than RDFLib
- it has a large number of classes/methods
  - listing, removing associated properties, objects
  - comparing full RDF graphs
  - manage typed literals
  - mapping Seq, Alt, etc. to Java constructs
  - etc.
- it has an “RDFS Reasoner”
  - a new model is created with an associated RDFS file
  - all the “inferred” properties, types are accessible
  - errors are checked
- and more…
Of course, it is much bigger and more complicated…
