The ESCAPE project is working toward the implementation of FAIR principles for Astrophysics ESFRI by using IVOA standards in the context of connecting the Virtual Observatory framework to the European Open Science Cloud. The scientists, software engineers, and data experts from the different facilities are addressing the ‘data stewardship’ challenges for a wide range of different data products and services. The recent ESCAPE Technology Forum event identified a number of important topics in the different domains from Radio Astronomy to Solar Physics: Connecting to the European Open Science Cloud Data stewardship of next-generation data products and services related to ESFRI and other astrophysics infrastructures M.
