Slides presented at the IASSIST 2022 Conference, in Gothenburg, Sweden, in the "Panel 1: CESSDA in ERA - collaborations, partnerships and perspectives", on 8 June 2022. Summary of the session: Presenting CESSDA ERIC wide range of current collaborations and partnerships, grouped in three areas: Research communities advancing the SSH research, European Research Infrastructures advancing the European Open Science Cloud (EOSC), European RIs advancing the Digital Future of Europe. For research communities advancing the SSH research - CESSDA is either participating in or supporting a number of projects and initiatives advancing the SSH research. Examples of the engagement with thematic communities via projects are EurHisFirm (dealing with historic economic data), COORDINATE (child and youth wellbeing), and HumMingBird (migration data community) projects. Connecting established infrastructures with new ones within the domain is another way of establishing a link with thematic communities via the SSHOC project, OPERAS (open publications), RESILIENCE (religious studies), and GGP (gender and generations programme) are welcomed as new and emerging ESFRI infrastructures. In the case of European Research Infrastructures advancing the European Open Science Cloud - CESSDA is connected to EOSC via several channels, the main being the coordination of the SSHOC (Social Sciences and Humanities Open Cloud) project, one of 5 cluster projects connecting thematic communities to EOSC, but also by participating in a number of other EOSC related projects like TRIPLE, EOSC Future or EOSC Enhance). For European RIs advancing the Digital Future of Europe - CESSDA is actively engaged in ERIC Forum Implementation project and RITrain Plus project, both gathering EU research infrastructures to work on common challenges (and in particular the need for educated and properly trained managers). Finally, the cross-domain collaboration is gaining momentum via alignment with other cluster projects (i.e. in SSHOC project), with other organisations and partners from different scientific domains (i.e. in EOSC Future project) and in the life-sciences domain in particular (i.e. BY-COVID project). In this session, examples were used to address some of the challenges, showcasing the results of collaborations in each of the above-mentioned areas and demonstrate the best practices used.
