Part 1: 9-10:15 am Open science skills for both research librarians and researchers are at the centre of all evolutions towards “openness”. Created in July 2018, LIBER's Digital Skills for Library staff and Researchers Working Group started working in two complementary directions: building a core skills set list, and spotting Open Science training programmes relying on skills identification. The first results of this combined approach were presented during this workshop, and follow on the 2018 LIBER/FOSTER+ workshop “Let’s build the skills!” and the EOSCpilot & LIBER Webinar “Skills and Training in Open Science and the EOSC ecosystem”. Part 2: 10:30 am-12:00 pm The second half of this workshop was a session shared with the SSH Open Cloud (SSHOC) project and the Digital Humanities and Digital Cultural Heritage Working group/Digital Skills for library staff and researchers. See presentations from the second half of the workshop.
