Semantic Technologies: Diamond in the Rough?11/25 Web Ontology Language (OWL) Built on top of RDF(S) and renaming DAML+OIL primitives Three layers: OWL Lite: a small subset, easier for frame-based tools to transition to, easier reasoning OWL DL: description logic, decidable reasoning OWL Full: RDF extension, allows meta-classes Several syntaxes: Abstract syntax: easier to read and write manually, closely corresponds to DL RDF/XML: OWL can be parsed as an RDF document, more verbose
