EIF Underlying Principle EIF Recommendation EULF Blueprint Recommendations
1. Subsidiarity and proportionality 1. Ensure that national interoperability frameworks and interoperability strategies are aligned with the EIF and, if needed, tailor and extend them to address the national context and needs.  
2. Openness 2. Publish the data you own as open data unless certain restrictions apply. Policy and Strategy Alignment (2); Return on Investment (16)
  3. Ensure a level playing field for open source software and demonstrate active and fair consideration of using open source software, taking into account the total cost of ownership of the solutions.   
  4. Give preference to open specifications, taking due account of the coverage of functional needs, maturity and market support and innovation Standardisation and Reuse (12)
3. Transparency 5. Ensure internal visibility and provide external interfaces for European public services. Policy and Strategy Alignment (2, 3)
4. Reusability 6. Reuse and share solutions and cooperate in the development of joint solutions when implementing European public service. Digital Government Integration (8); Standardisation and Reuse (11); Governance, Partnerships and Capabilities (19)
  7. Reuse and share information and data when implementing European public services, unless certain privacy or confidentiality restrictions apply. Standardisation and Reuse (11)
5. Technological neutrality and data portability 8. Do not impose any technological solutions on citizens, businesses and other administrations that are technology-specific or disproportionate to their real needs.  Policy and Strategy Alignment (5); Standardisation and Reuse (10, 12)
  9. Ensure data portability, namely that data is easily transferable between systems and applications supporting the implementation and evolution of European public services without unjustified restrictions, if legally possible.  Digital Government Integration (7)
6User centricity 10. Use multiple channels to provide the European public service, to ensure that users can select the channel that best suits their needs.

10. Administrative simplification 17. Simplify processes and use digital channels whenever appropriate for the delivery of European public services, to respond promptly and with high quality to users' requests and reduce the administrative burden on public administrations, businesses and citizens.  Digital Government Integration (6)
11. Preservation of information 18. Formulate a long-term preservation policy for information related to European public services and especially for information that is exchanged across borders.   
12. Assessment of effectiveness and efficiency 19. Evaluate the effectiveness and efficiency of different interoperability solutions and technological options considering user needs, proportionality and balance between costs and benefits. Return on Investment (14, 15)


Interoperability Layers

EIF Interoperability Layers EIF Recommendation EULF Blueprint Recommendations
1. Interoperability governance 20. Ensure holistic governance of interoperability activities across administrative levels and sectors.  Policy and Strategy Alignment (12); Digital Government Integration (7); Governance, Partnerships and Capabilities (17)
  21. Put in place processes to select relevant standards and specifications, evaluate them, monitor their implementation, check compliance and test their interoperability. Standardisation and Reuse (12)
  22. Use a structured, transparent, objective and common approach to assessing and selecting standards and specifications. Take into account relevant EU recommendations and seek to make the approach consistent across borders. Standardisation and Reuse (12)
  23. Consult relevant catalogues of standards, specifications and guidelines at national and EU level, in accordance with your NIF and relevant DIFs, when procuring and developing ICT solutions. Policy and Strategy Alignment (5); Standardisation and Reuse (12)
  24. Actively participate in standardisation work relevant to your needs to ensure your requirements are met. Standardisation and Reuse (12)
2. Integrated public service governance 25. Ensure interoperability and coordination over time when operating and delivering integrated public services by putting in place the necessary governance structure. Governance, Partnerships and Capabilities (17)
  26. Establish interoperability agreements in all layers, complemented by operational agreements and change management procedures. Governance, Partnerships and Capabilities (18)
3. Legal interoperability 27. Ensure that legislation is screened by means of ‘interoperability checks’, to identify any barriers to interoperability. When drafting legislation to establish a European public service, seek to make it consistent with relevant legislation, perform a ‘digital check’ and consider data protection requirements. Policy and Strategy Alignment (1)

The use of common vocabularies for expressing metadata is recommended. Standardisation and Reuse (13)
  43. Communicate clearly the right to access and reuse open data. The legal regimes for facilitating access and reuse, such as licences, should be standardised as much as possible.  Policy and Strategy Alignment (2)
