3. Platforms: why?
• Publishing of data as part of the open innovation in the public
sector
• Integrated solution based on existing off-the-shelf software
Data Portal + Data Registry + Triple Store
• To add freshness and value using dynamic data from sensors
• Provides a one-stop-shop experience that enables
development of novel applications
• Other benefits: metadata schema for data sets; linked data;
apps gallery; wiki for developers; search engine; …

4. Two platforms
1. Open Data platform:
• Open Data Portal – Liferay; Open Data Registry - CKAN
• Linked Data Store – Virtuoso; Data Enrichment Tools - Google Refine
• Integration Middleware: Java API for CKAN and Virtuoso
2. Open Sensor Networks Platform:
• Core system: linked to CKAN repository, delivers Metadata and Open
Data using standard formats (JSON, XML)
• High speed database: storage for sensor measurements (Apache
Cassandra)
• REST web services as common and simple interface to interact

15. Support to developers
 Tutorials and libraries to help developers
participation to Open Data challenges
 Basic tutorials in the main mobile technology (Android,
iOS and Windows Phone) to set up the environment
 Examples to obtain metadata and OpenData (pieces of
code as an example, where to find them)

16. Support to developers
 Wiki documentation

17. Support to developers
 Google code
http://code.google.com/p/osn-samples/

18. Support to developers
 Augmented reality Android app
 Data used

19. Support to developers
 Augmented reality Android application
 Functionality
1  When user enters, the application
information from the city will be
downloaded.
 Automatically locates the user in
their position
 Possibility of searching for a
concrete direction

20. Support to developers
 Extended information from data-sets

21. Support to developers
 Augmented reality
 Augmented Reality: the information on
the map will be shown through the phone
camera, drawing the point in over the
image in real time and moving according
to the mobile orientation.
 Radar: a radar will show the position of
the requested points in a two dimension
plane and rotated according to the
direction faced by the user.

22. We encourage both …
… cities to feed the platforms
… and developers to join the Open Cities
Challenge!
