This deliverable is the first output within Task 4 - Training tools and actions - of the FIT4RRI project. The Task is focused on the adoption of Responsible Research and Innovation/Open Science (RRI/OS) good practices in research funding and performing organizations (RFPOs). The purpose of this FIT4RRI output - a Content mapping and meta-analysis of RRI/OS training - is to support the training activities carried out by the consortium partners, as well as the testing, in different RFPOs, of procedures triggering the kind of institutional change that favors new governance settings and new training approaches. This deliverable specifies the rationale applied in the content mapping, together with a classificatory scheme and a training-related taxonomy that seeks to encompass key dimensions of both RRI and OS that are themselves driven by expected learning outcomes. The proposed taxonomy and classificatory scheme rest heavily on the combined experience of FOSTER and RRI Tools networks, accumulated during a four-year long period of reflexive practice within a wide European alliance of RRI/OS actors and stakeholders. In addition, the deliverable puts forward an initial core of resources/content for RRI/OS training, compiled and mapped in compliance with the proposed taxonomy and classificatory scheme. Given the fast growing body of RRI/OS knowledge, practices and tools, this is a dynamic content mapping that is designed to be fed and nurtured by the unfolding of the FIT4RRI tasks and actions. This preliminary content is presented alongside a meta-analysis of the resources, which are themselves largely based of the most effective and far reaching resources compiled by both the FOSTER and RRI Tools projects.
