Presentations during the Kick off session of the OpenAIRE Week, General Assembly. Practical implementation is the next step in making Open Science work. How can this work at an international and European level, and what does this mean in terms of implementing EOSC? In this webinar, the audience got a first-hand look at the draft UNESCO recommendation on Open Science and partnership for Open Science. The session also outlined the role of OpenAIRE in EOSC and focused on national efforts to implement elements of EOSC at national level.
