Licenses specify precisely the conditions of reuse of resources, i.e., what actions are permitted, obliged, and prohibited when using resources. Knowing the compatibility of a license allows knowing to what extent the protected resource is reusable. CaLi is a lattice-based model that partially orders licenses in terms of compatibility and compliance. It uses restrictiveness relations that are refined with constraints to take into account the semantics of actions existing in licenses. In this demonstration, we propose an online Web tool that interactively shows how to define the compatibility of licenses as partial orders with the CaLi model.
