Using Linked Data• Sparql (like SQL, but graphier)
• Browsing to a URI– HTML for humans– Raw data for machines
CRAB LOD (ALPHA-release)http://data.vlaanderen.be/sparql
Use Case
Local News
Local NewsNews annotated with location
• City administration (eg: Ghent)• Utility companies (eg: Eandis)
App knows users interests and location
User gets relevant news
