Introduction
  • RDF is basis for the world of the Semantic Web.
  • RDF Schema is the vocabulary description language
    for defining simple ontology classes in RDF.

3
Agenda
  • Rudimentary ontology
  • RDF Schema (RDFS) language

RDF Part Played by RDFS
  • RDF describes resources over the Internet.
  • RDFS is used to create class hierarchies for the
    classification and description of resources.
  • Domain-neutral lightweight schema language.
  • Its vocabulary description is written in RDF.
