Abstract
Free and open source software (FOSS) has undoubtedly become an important element of intellectual property law. It is therefore not surprising that the European Commission developed its own non-proprietary licence, i.e. the European Union Public Licence (EUPL). The article examines the reference to ‘a work of software’ to determine the scope of the licence. For this purpose, the paper discusses the reasons for the creation of the EUPL, the relationship between a work and software as well as the structure of a computer program. The following considerations also include the compatible licences listed in the EUPL Appendix. The article concludes that the reference to a work or software is not accidental because it removes serious doubts arising from the concept of a computer program. Thus, this legal solution may facilitate the wider adoption of the licence.
