  4. 4. Why Linked Open Data? • It’s cool • “Increase and Diffusion of Knowledge” • Share, contribute to a global database • Create context around data • Allow data to be reused/repurposed by creators and a worldwide community • Improve discoverability of content
  5. 5. So Just what is Linked Data• Publishing structured data on the web• RDF (Resource Description Framework)• Enables queries computer 2 computer• uses standard ontologies (vocabularies) • data in “triples” (“triplestore”)

  7. 7. Some Linked Data Buzzwords, er StandardsRDF, OWL, SPARQL,RDFa, SKOS,RDFS, GRDDL,POWDER, RIF,SAWSDL, RDB2RDF
  8. 8. Linked Data Design Issues“The Semantic Web isn’t just about putting data on the web. It isabout making links, so that a person or machine can explore theweb of data. With linked data, when you have some of it, you canfind other, related, data.” Tim Berners-Lee, Linked Data – Design Issues1. Use URIs as names for things.2. Use HTTP URIs so people can look up those things.3. When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL). 4. Include links to other URIs, so they can discover more things.  http://www.w3.org/DesignIssues/LinkedData.html
  9. 9. * On the web, open ** Machine-readable data *** Non-Propriety format **** RDF Standards Linked RDF*****
  10. 10. DBpedia is a community effort to extract structuredinformation from Wikipedia and to make this informationavailable on the Web. DBpedia allows you to asksophisticated queries against Wikipedia, and to link otherdata sets on the Web to Wikipedia data.
  11. 11. The three sides of the tri-color cube in these logos evokethe triplet of the RDF model. The peeled back lid invitesyou to Open Your Data to the Semantic Web!
