The Semantic Web and Why You Should Care.

  2. or The Semantic Web and why you should care
  3. Semantic Web
  4. Semantic Web
  5. Semantic
  6. meaning
  7. machine readable
  8. machine readable meaning
  9. self-describing machine readable meaning
  10. Why RDF? self-describing machine readable meaning
  11. What is RDF?
  12. RDF is a model predicate subject object
  13. Is that it?
  14. Yes, that’s it. predicate subject object
  15. The model can be serialized as XML
  16. The model can be serialized as XML It’s pig ugly
  17. The model can be serialized as XML It’s pig ugly That’s fine. Machines eat ugly for breakfast
  18. Honestly, don’t worry RDF != RDF/XML
  19. Our model can describe models
  20. Specific Models
  21. Specific Models About stuff
  22. Specific Models About Things
  23. Specific Models About Things Let’s call these ontologies
  24. This Is The Most Informal Talk You Will Ever Hear About a Formal Topic Ben Fields - Goldsmiths University of London Kevin Page - University of Southampton
  25. Ontologies are described in OWL
  26. Ontologies are described in OWL OWL is modeled in RDF
  27. RDF is machine readable
  28. RDF is machine readable So ontologies can understood by machines

  30. Even if that’s just to assert that everything is a Thing

  32. Semantic Web
  33. Semantic Web
  34. Web
  35. The Web is simply the biggest, most successful, most useable, distributed systems architecture ever.
  36. “The Web is simply the biggest, most successful, most useable, distributed systems architecture ever.” David De Roure
  37. Linking
  38. Linking Scale
  39. The mechanism for Linking enables the Web to Scale
  40. Do people scale?
  41. Do people scale? Do people scale to the size of the Web?
  42. machine readable meaning
  43. Why does the Web scale?
  44. REST
  45. A Resource Oriented Architecture
  46. A Resource Oriented Architecture with a simple protocol to return representations of those resources
  47. HTTP returns those representations
  48. HTTP returns those representations When it talks to us, it returns HTML
  49. The resources are simply addressable objects
  50. so ur ce Re What is RDF? e wor k nFram ri p t io De sc
  51. About those addressable Things...
  52. We address them using URIs

  56. Everything in RDF is a resource
  57. Everything in RDF is a URI
  58. ot q u i te n Yes, that’s ^it. predicate subject object I U R I I U R U R
  59. Why is this important to second generation digital libraries?
  60. Principally libraries are about sharing
  61. Principally libraries are about sharing Things.
  62. Do people scale?
  63. Do people scale? Do people scale to the size of the Web?
  64. machine readable meaning
  65. Demo?
  66. Questions?
