Which license should you add to your software to make it FAIR?

This is the first blog in the series Simple steps towards FAIR code and software . One of the most asked questions by researchers to RDM Support regarding the publication of code or software is: Which license should I add to my software to make it FAIR? In this blog post, we ask Jonathan de Bruin Disclaimer:  This blog is an expert interview. No rights can be derived from it. So, tell me, what software license do we add to our research code and software?. '(ha-ha) This is exactly what most researchers ask! Although it doesn't have to be a complicated answer, it's not possible to answer this question with a single license. The best license for your code or software depends on multiple things like the wishes of you and your colleagues, details of your project, and recommendations of your funders or university. Our university, Utrecht University, promotes an open attitude where open and FAIR publishing of research code and software is a key aspect.
