Presentation at the National ICT Conference in Tbilisi, Georgia, November 2013

1. International experiences on Interoperability

November 28-29, Tbilisi, Georgia

2. The Greek Interoperability Centre (GIC)
A European Research Infrastructure, supported by the FP7
Programme, launched in 2008
The centre aims at:
•
•
•
•
•
Promoting Interoperability in eGovernment and eBusiness in SouthEastern Europe and the Mediterranean
Demonstrating state of the art solutions for Interoperability in Digital
Public Services
Contributing to Interoperability Standardisation and Research
Acting as a dissemination and engagement point for research centres,
administrations and enterprises.
The Centre is already in close collaboration with FOKUS (DE), NCC (UK)
and other interoperability excellence centres

3. Motivation for Interoperability in
eGovernment
Too many public organizations that need to cooperate during service
provision (i.e. in Greece 20 ministries, 13 prefectures, 52 districts, 330
municipalities, 1800 public admin. organizations, 10000 Governmental
“Points of Service” in total)
Not manageable knowledge around the services. Sometimes even the
exact number of services cannot be estimated (in Greece: more than
2,000 governmental services)
Many large- and small-scale projects that have not been based on any
interoperability standards (need for retrofit)
Most approaches to finding solutions to the interoperability challenges
are targeting technical specifications of the proposed systems
We need approaches not stopping in paper-based specifications, but
providing a real system supporting interoperability in the public sector

15. Lessons Learnt


Nation-wide initiatives for one-stop service provision have to combine content
syndicating portals, service registries and relevant standardisation in a
coordinated effort.
Service digitization has to be coupled with transformation, in order to ensure
service delivery to citizens but also long-term growth and sustainability.
Interoperability standardisation has to be supported by collaborative platforms,
than just be in paper format, in order to assist diffusion within the public
sector.
Training and dissemination has to get a significant amount of a large
eGovernment project effort and budget, as diffusion within the public sector
and citizens is of key importance.
Interoperability Infrastructures need to be supported by appropriate changes to
the legal framework at national level in order to be applied in e-Government
services.
The follow-the-service approach is a very valuable tool, greatly assisting
focusing on actual and measurable goals.

19. Conclusions and Next Steps
•
Interoperability in digital public services cannot be achieved without process reorganization, legal system re-structuring and data re-work
•
Interoperability Infrastructures can greatly assist in driving innovation in
eGovernment, rather than just providing the “standards”
•
At European level, the coordinated management of pan-european services is
needed (Services Directive, SEMIC, CEN/ISSS). Interoperability Infrastructures
will have to be deployed at cross-country level.
•
In Greece, more emphasis laid now on tools like:
-
XSDGenerator: automated XSDs development and management
-
Tools for Management of eGIF Standards and Specifications
-
Tools for Assessment of public sites and administrations
-
Advanced eParticipation functionalities for governmental committees
•
Interoperability solution sourcing and deployment needs specialised centres of
excellence
•
Go on – you can do it !
