Call for proposals: help scale interoperability across Europe with the next “Interoperable Europe solutions”

Interoperable Europe is inviting public administrations and the wider interoperability community to propose mature, reusable solutions that can be recommended EU‑wide and promoted for adoption.  

The invitation follows the third meeting of the Interoperable Europe Board (held in Brussels on 4 December 2025), where Member States and the European Commission advanced two major milestones of the Interoperable Europe Act: adoption of the first Interoperable Europe Agenda and endorsement of the first labelled “Interoperable Europe solutions.”  

What are “Interoperable Europe solutions”? 

Interoperable Europe solutions are solutions recommended by the Interoperable Europe Board because they are highly reusable and align with the board’s needs and priorities for building better interoperable digital public services.  

“Solutions” can include shared building blocks that public administrations can reuse across systems and borders such as common data models and technical specifications that make it easier for administrations to exchange data and design compatible services.  

The label is designed to spotlight mature, reusable interoperability solutions that should be considered in the context of interoperability assessments, making it easier for administrations to identify trusted components rather than reinventing them separately.  

The first labelled solutions 

The board’s first endorsed set illustrates the type of impact the label is meant to amplify: 

• Core Vocabularies — reusable data models for public administrations (covering key concepts such as persons, organisations/businesses, locations, etc.) that facilitate system integration, data publishing, and the design of new systems across borders and sectors.  

• Data Catalogue vocabulary (DCAT‑AP) — a common specification for metadata records and data catalogues that helps make public‑sector data easier to discover, exchange and reuse across European data portals, supporting semantic interoperability through standardised dataset descriptions.  

A direct invitation to propose the next solutions 

If your organisation maintains a solution that is already mature and in use, or has strong potential to be reused broadly, this is a chance to help shape the EU’s shared interoperability toolkit and increase your solution’s visibility for adoption across Member States.  

To be considered for the Interoperable Europe solution label, proposals must meet the general criteria adopted by the board: needs and user centricity, reusability, security and data privacy, openness, sustainability.  

How to submit? 

To submit a proposal for a solution you need to complete a questionnaire and provide details about the solution. The Interoperable Europe Board will later review the submissions against the criteria. If approved, the solution receives the official “Interoperable Europe solution” label, supporting recognition and adoption by public administrations across the EU.
