RDF Schemas
Classes, Resources, …


  • RDFS defines the terms of resources and classes:
    • everything in RDF is a “resource”
    • “classes” are also resources, but…
    • they are also a collection of possible resources (i.e., individuals)
  • Relationships are defined among classes/resources:
    • “typing”: an individual belongs to a specific class
    • “subclassing”: instance of one is also the instance of the other
      • a bit like in object-based programming…
      • …but the same resource can have several types
