This session reports on the development of the 5-star Linked Open Data Address Register. The first product released by the Flemish Government in line with the Linked Data principles is the Central Reference Address Database (CRAB), containing well over 4 million addresses and their geographical coordinates. The addresses are synchronised in real time between 308 local governments and the Linked Base registry.

12. BASE REGISTRIES
For the public sector, Base
Registries are a fundamental
footprint like DNA for living
organisms.
“trusted authentic sources of
information under the control
of an appointed public
administration or organization

machines don’t need to guess.

22. Key Point
Each term has a specific definition.
By reusing terms now,
we create solutions that are interoperable later.

23. Using Linked Data
• Sparql (like SQL, but graphier)
• Browsing to a URI
– HTML for humans
– Raw data for machines

24. CRAB LOD(ALPHA-release)
http://data.vlaanderen.be/sparql

25. Use Case

26. Local News

27. Local News
News annotated with location
• City administration (eg: Ghent)
• Utility companies (eg: Eandis)
App knows users interests and location
User gets relevant news
