Disclaimer: I am not sure this is the right place to ask the question, but since it is directly related to academic work, I though I'll give it a try. If it is not, please feel free to redirect
Together with colleagues from different institutions (all academic), we have been developing a new information language (more precisely a format), based on XML, to store a specific type of information. This format is primarily directed to the academic world and will be open source
My question is: do we need to attach a licence to this new format and, if yes, what type of licence is suitable for that?
