Research, and how it is conducted, is ever-changing and requires those that are tasked in its support to also keep up-to-date in Research Data Management, Open Access and Open Science in general. OpenAIRE's train-the-trainer bootcamps aim at empowering trainers with the knowledge and the know-hows of Open Science so they can pass it onto the researchers and students themselves, and ultimately help create a more open, transparent and accessible research ecosystem.
