The aim of the Working Group (WG) is to collect, prepare, edit and make available through HOSI website educational material on Open Science. The educational material should be aimed at scientists, researchers, but also the general public, presenting the basic principles of Open Science (publications, data, software, services) and then delving into specific areas where appropriate (e.g. data management plans, data stewards). The educational material will be used in the context of HOSI training activities, other trainers, but also by anyone interested.
