Self descriptiveness of RDF data

  1. 1. Self-Descriptiveness of Ontologies Fariz Darari
  2. 2. A Good Ontology Must Be Self-Descriptive!When someone uses a term from the ontology, she must be able to find out the real meaning of the term by following/dereferencing its URI.
  3. 3. Example: <http://purl.org/dc/terms/license><http://example.org/thisDocument> <http://example.org/cc-by> Icons by: David Vignoni - http://www.icon-king.com/ Yingjunjiu - http://yingjunjiu.deviantart.com
  4. 4. The example showed that this document’s license is CC-BY.The example uses the term license from the Dublin Core ontology, meaning:“A legal document giving official permission to do something with the resource.”
  5. 5. Oh yeah?For sure, because when I dereferenced the URI: http://purl.org/dc/terms/licenseI got exactly this description: PS: Yes, DC ontology is a good one :)
  6. 6. OK, I believe you now! Icon: VistaICO.com - http://www.vistaico.com
  7. 7. What about the other ontologies?• FOAF• OWL• dbpprop (DBpedia)• geo• BIBO (Books)• VoID (Vocabulary of Interlinked Datasets)
