Outline

• Vision for interoperability

• Problem statement

• Challenges and solutions

• The Citadel On the Move approach

Vision

• Improve public sector data interoperability– Across member states– Within member states

• European governments being open, flexible and collaborative in their relations with citizens and businesses (Malmö Vision)

• Common architecture (Citadel statement, ISA – EIA action)

Problem statement

• EU Directive on re-use of PSI– 27 Member States implement the directive– A lot of data published by public authorities

• But...– In what format?– No real focus on access to citizens or businesses– Interoperability (nationally or internationally) not

yet a core consideration

Challenges & Solutions• Semantic

– Lack of (common) semantics– Common data/meta-data models– Core vocabularies– CITADEL, ENGAGE

• Technological– Ways to upload, download, maintain datasets exist– Ways to search, link, visualise, use in applications also exist– Infrastructures– Semantic Web “stack” of standard technologies– Joinup platform, ISA programme, LOD2, CITADEL

• Legal/policy– Licensing– Contractual and intellectual property rights associated with the data– LAPSI project, ISA programme, ePractice.eu, +Spaces, WeGov, CITADEL

Challenges & Solutions• Privacy

– Personal, health, financial data, national security etc– epSOS

• Language– eGovernment services provided internationally poses challenges– CITADEL, ENGAGE

• Data Quality, Evolution, Provenance– Is the data we find of appropriate quality? Has it changed and how?

Who owns it?– DIACHRON

• Financial– Cost of publishing data in a way which facilitates interoperability– What happens to data which has already been published?

Within the context of Citadel... On the Move

• CITADEL will provide:– application templates to facilitate apps/services

development by citizens (non-professional developers)– a repository of data and tools to facilitate finding and

retrieving the right data (Open Data Commons, Citadel Hub)

• Will create communities of citizen developers• Will use (at first) existing datasets published by PAs in

Athens, Manchester, Issy, Ghent• An application created in Issy must be re-usable in

Ghent
