The Semantic Web

What is it?

• A vision of Tim Berners-Lee,

• intended to create "the web of knowledge",

• by annotating meta-data to web pages & evaluation.

How is it supposed to work?

• On top of a layered software & meta-data model:
  • Trust-Relations (digital signatures)
  • Proof (proof languages)
  • Logic (reasoning, inference)
  • Ontology (term relationships, taxonomies)
    DAML, OIL, OWL
  • RDF (semantics definition)
  • XML (syntax definition)
