Understanding the EUPL and Open Licensing
The European Union Public Licence (EUPL) is the first open-source licence with a working value in all EU official languages. It is reasonably "share-alike/reciprocal," like the LGPL, but also covers remote distribution.
Everyone in the world (and not Europeans only): IT developers, practitioners, and users who need guidance in defining the conditions under which a solution may be freely shared and reused, considering the legal framework.
Clear licensing rules form the regulatory basis for sharing and reusing software solutions while supporting legal interoperability. While the EUPL ensures these principles, other licences may also facilitate compatibility and interoperability.
By Decision C (2021) 8759, the EUPL is provided for European Commission distributed software.
According to the Interoperable Europe Act (8.4) all public sector portals providing open source solutions shall allow for the use of the EUPL.
