Let us keep to the Semantic Web for now…

• In what follows we will restrict ourselves to the Semantic Web

• • a way to specify data and data relationships
  • allows data to be shared and reused across application, enterprise, and community boundaries
  • emphasis on the Web aspect:
  • • scale, inherent lack of knowledge, possible inconsistencies
    • possibility to combine everything that can be identifed via a URI
  • a collection of fundamental technologies (RDF/S, OWL, GRDDL, SPARQL, …)
