As an early stage career researcher, coming from the field of biomedicine, researching on data sharing, I was curious to find about overall data-sharing practices, all over the world, across all disciplines. In the beginning, I was afraid that I would not be able to understand that IT language. It turns out that the things are not complicated at all, similar principles were woven through all the sessions I was present in: yes, there is a need to share data, yes it could be complicated, yes there is a need to work on interoperability, infrastructure, etc... And everybody agreed that persistent identifiers are a must.
