Everything You Wanted to Know about the EUPL

Well, not quite, but this post from the splendidly-named TechnoLlama gives some very useful information about an "expert meeting" that discussed the otherwise slightly obscure European Union Public Licence:

On Friday 25 January I attended an expert meeting discussing the European Union Public Licence (EUPL). This is the latest member of the growing open source licence ecology, and if I must say so, it is quite a nicely drafted document (biased opinion warning, as I helped in checking the Spanish translation). The licence is initially intended to be used as the official licence for projects funded under the IDABC framework, but it is also intended to be the first open source licence with an officially sanctioned translation into 23 official languages of the EU, which in my opinion makes it particularly useful for public sector administrations across the continent. This I think is a great example of the importance given to open source by the European Commission.

There are three main features in the licence that I think make it useful. The first is that it is its clear language and largely unambiguous wording, which make it easier to understand than other licences out there (*cough* GPL v3 *cough*). Secondly, the licence contains a small yet functional patent clause. Thirdly, it has a clever compatibility clause which allows wider freedom to developers in order to release modifications under one of the compatible licences, namely GPL (v2), OSL, CPL, EPL and Cecill.
