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
