The report of the Pissarides committee proposes:
The Interoperability Center (KE.D) of the Ministry of Digital Governance is the information system developed by the General Secretariat of Public Administration Information Systems, with the aim of interconnecting the electronic services of the Public Administration (Government Gazette 3990/B/1-11-2019).
The Interoperability Center (KE.D) ensures a single environment (infrastructure) for the installation and use of online services, through which operational data is exchanged between the Public Bodies.
With the Ministerial Decision 38428 (2021) the presentation of supporting documents is replaced, where possible, through the interconnection of systems and through the use of web services of the Interoperability Center.
Therefore, the proposal is assessed as partially implemented, as the scope of the principle in the Greek public sector has not been defined and has not been extended to the single market in the context of the free movement of data and digital services in the EU.
