The document discusses the importance of a 5-star linked open data address registry in smart city development, emphasizing the integration of information technology with infrastructure. It introduces the Central Reference Address Database (CRAB) in Flanders, which synchronizes over 4 million addresses in real-time across local governments. The document also promotes a workshop aimed at leveraging linked data for local decision-making and innovation in public services.

2. WHYSmart Cities need to be connected.
Smart Cities: ”Places where
information technology is
combined with infrastructure,
architecture, everyday objects,
and even our bodies to address
social, economic, and
environmental problems1”.

3. HOWSilos will have to dissolve.
“The development of 5-star
Linked Base Registries1 is seen
as a part of a solution to
overcome this hurdle”

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
appointed by the
government1” containing
information about public
services

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
