    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

    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
    29. 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
    30. Even if that’s just to assert that everything is a Thing

    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

    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

    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?
