Hello, One of my favorite wikimedia project is the wiktionary, I probably use it everyday and I like to contribute on the french chapter here and there. As I'm learning esperanto, I wanted to improve the french wiktionary on this topic. My first thought was to begin by gathering a list of vocabulary, make a todo page with links and go on. But I found that there is already a free/libre dictionary out there : Reta Vortaro[1]. Morever this dictionary provide definition in several languages, so I thought instead of making a word by word contribution only for the french chapter, I could add a whole esperanto dictionary to several chapters in once. It sounds great doesn't it ? Unfortunately, this dictionary is under GPL which is a well known free license (but a strange choice for a non-software project). So I would like to know, can I mix up a GPL content with a CC-by-sa page (in cases where such a page already exist), and more generaly can I add GPL content into the wiktionary. If no, could we approach their community and ask them for a relicensing under CC-by-sa, so we could add their great work into our wiktionaries. I also send this message to email I found to contact them[2]. Kind regards, mathieu [1] http://purl.org/NET/voko/revo/ [2] http://reta-vortaro.de/revo/dok/revolist.html
