  15. 15. LINKED DATA isa set of (simple)principles for thesemantic webCredit: Thomas Hawk, http://flic.kr/p/rFb2Q
  16. 16. principle 1.use URIsas NAMESfor THINGS
  17. 17. this URI: http://linkeddatabook.com/editions/1.0/#bookidentifies the book:Linked Data: Evolving the Web into a Global Data Space (1st Edition) by Tom Heath and Christian Bizer
  18. 18. principle 2.use HTTP URIsso that peoplecan LOOK UPthose NAMES
  19. 19. using a HTTP URIas a NAME allows us to get DATA about a THING using the web (which you probably know how to use)
  20. 20. in other words,principle 1+2:unambiguous namesthat allow us to know HOW and WHERE to get information Credit: Tom Woodward, http://flic.kr/p/a6ND3Y
  21. 21. principle 3.when someone looksup a URI, provideuseful INFORMATION,using the STANDARDSof the semantic web
  22. 22. semantic web standards provide a flexible & expressive structure using these principles! Credit: United States National Archives, http://flic.kr/p/d7DvX9
  23. 23. principle 4.include LINKS toother URIs sopeople can findmore THINGS
  24. 24. LINKS arerelationshipsbetweenTHINGS thatare namedby their URIsCredit: Ethan Hein, http://flic.kr/p/9mfF1z
  25. 25. RDF foris the basis Resource Description Frameworkmany semanticweb standardsCredit: Gregory Williams, http://flic.kr/p/5ybibi
  26. 26. RDFlets us make statementsabout things consistentlyCredit: Kat Masback, http://flic.kr/p/KiXjE
  27. 27. RDF statements have a subject http://matienzo.org/#mea predicate http://xmlns.com/foaf/0.1/givenName an object “Mark”& are called TRIPLES
  28. 28. GRAPHS are setsof RDF triplesCredit: Ed Summers, http://inkdroid.org/journal/2008/09/11/nkoscendi/
