  7. The Web of Data • Use URIs as names for things • Use HTTP URIs so that people can look up those names. • When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL) • Include links to other URIs so that they can discover more things. Tim Berners-Lee (2006)

  8. English sentence Brideshead Revisited was written by Evelyn Waugh.

  9. Entities and Relationship Brideshead revisited created by Evelyn Waugh

  10. Adding URIs: Brideshead revisited http://id.loc.gov/authorities/names/no97080492 created by Evelyn Waugh
