The DESIR Winter School "Shaping new approaches to data management in arts and humanities" took place in Lisbon on 10-13 December 2019. The event was hosted by NOVA FCSH University facilities and was organised in the framework of the Horizon 2020 funded project DESIR (DARIAH ERIC Sustainability Refined). It aimed at gathering PhD students, arts and humanities scholars from all career stages and research managers interested in the issues raised by sustainable practices to open up data in the arts and humanities. The event was a joint organisation between DARIAH and NOVA FCSH. As such, it brought together the collaboration of national and European experts in the data management field. Sharing knowledge, research outputs and other scholarly resources in ways that are tuned for long-term availability and maximal use and reuse are recognized as essential practices but also key challenges for arts and humanities research. In the last couple of years, this need has also been recognized in a strong political drive in the European Union giving rise to support structures but also policy imperatives for research data management. As a result, Research data management emerged to be a new field of expertise to explore and establish in all range of disciplines. The fact that the concept of data in the arts and humanities domain is far from being a straightforward one adds further complexities to the implementation of such policies in the arts and humanities domain. To meaningfully address the real data needs of the diverse communities of arts and humanities scholars in terms of skills, infrastructure and best practices, we need to keep a reflexive and open exchange about the function of data in specific research questions and fields of enquiry. The DESIR Winter School provided a unique opportunity for arts and humanities scholars as well as for librarians and research managers to learn about how to maximize the potential of their scholarly resources and to take practical steps in opening up their research in ethically and legally responsible ways. To this end, the DESIR Winter School covered a wide selection of topics ranging from the optimal implementation of FAIR data in the arts and humanities, issues around ethics, Intellectual Property Rights and licensing, data and software citation practices, open research notebooks and innovative publishing practices in the arts and humanities. The main goals of the Winter School were to: • Introduce scientific and academic communities in the arts and humanities to the principles and practices of responsible research and Open Science; • Strengthen the skills of the arts and humanities communities in research data management, curation, sharing, preservation and reuse; • Enable R&D and Higher Education institutions to develop research data strategies and policies; • Foster national and international collaboration amongst the diverse research communities in the arts and humanities; • Introduce participants to innovative publishing practices in the arts and humanities, such as data journals, overlay journals etc.
