  • What is an Ontology?
    an ontology defines a set of representational primitives with which to model a domain of knowledge or discourse.
    http://en.wikipedia.org/wiki/Ontology_(information_science)
  • 6. My Definition of an Ontology
    An Ontology is the language, or vocabulary used by practitioners in a specific domain.
    Essentially it is a controlled vocabulary for a specific subject area,
    Geographic Names Ontology defines terms for things like:
    Park, Shelf, Saddle
    Terms might have different means if using a different ontology
  • 7. Sample RDF can describe members

  • 15. Linked Data principles
    Tim Berners-Lee:
    Use URIs as names for things
    Use HTTP URIs so that people can look up those names using the web
    When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL)
    Include links to other URIs so that people can discover more things

  • 28. Requesting RDF using an Accept Header
    curl -H "Accept: application/rdf+xml" -X GET http://vivo.ufl.edu/display/n25562
  • 29.
  • 30. Querying Triples with SPARQL
    By individual URI (subject or object)
    Everything about one event, a grant, a person
    By property relationship (verb)
    All organizations that are part of another
    By type
    Everything with an rdf:type of Event, Person, or Project
    By combinations of the above
    SPARQL leverages the RDF format to focus on the data
