Weak copyleft

European Union Public Licence 1.2

An EU-origin copyleft license designed for public-sector and interoperable software, with multilingual authentic texts.

Compared to common options: EU-focused copyleft with compatibility provisions; not a drop-in MIT/Apache substitute — read EUPL compatibility notes.

Generally allows

  • Commercial use
  • Modification
  • Distribution
  • Communication to the public
  • Private use

Typically requires

  • Provide source when distributing or communicating the work
  • Retain notices
  • License derivatives under EUPL or a compatible license listed by the EUPL

Watch-outs

  • Removing copyright notices
  • Holding authors liable beyond the licence terms

How teams usually use it

  1. Relevant for European public administrations and projects targeting EU interoperability.
  2. Read the compatibility provisions before combining EUPL code with other copyleft licenses.
  3. Use official EUPL texts and supporting material from Interoperable Europe / Joinup rather than unofficial summaries.
