On Thursday 25 May 2023 FAIR-IMPACT organised a workshop on the topic of PIDs in complex data citation, semantic artefacts and related services. The project invited relevant projects and initiatives to provide an update on their related work and the ambition is to work together on defining community best practices on PIDs and complex data citation. The workshop also touched upon topics of common interests around citation, versioning and research object types. The aim was to achieve a more coherent implementation of PIDs, leading to more exact data citation and a broader and more targeted use of PIDs. The presentation given during the workshop are collected here.
