Enabling Interoperable Europe

The SEMIC Support Centre is the first step on a journey to become an interoperable European administration. In line with the Interoperable Europe Act, the SEMIC community stands for co-creation and sharing best practices. The Support Center is also home to a community of adopters that share tooling, standards and good practices to promote semantic interoperability.  

Who is it for?

Are you a policy officer or a technical expert working on data sharing and reuse? SEMIC and its support centre offers several services that aim to help public administrations share their experience with each other and help each other out in making the single market of data a reality.

In the spotlight: SEMIC Roadshow in Romania

On 9 and 10 March 2023, our colleagues from Romania hosted the SEMIC Team in Bucharest to exchange good practices and learn from each other on various interoperability topics. Find out more about it here.
