The whitepaper "Onboarding EOSC hub: best practices and lessons learnt" has been produced by the NEANIAS project.

The NEANIAS EU project develops and integrates services to EOSC in the field of Underwater, Atmospheric and Space research. The objective is to share these thematic services with scientific researchers of EOSC communities on these fields and beyond. The project completed the development and EOSC onboarding of 4 of its thematic services: SPACE-VIS ViaLactea, UW-MAP, ATMO-FLUD and SPACE-ML CAESAR. This white paper reports on the EOSC onboarding experience, i.e., on the registration of these services in the EOSC Portal and summarises the lessons learnt during the process.

At the time of writing this whitepaper, the project completed the development and EOSC onboarding of 4 of its thematic services: SPACE-VIS ViaLactea Service [2], UW-MAP [3], ATMO-FLUD [4], SPACE-ML CAESAR service [5]. This whitepaper reports on the EOSC onboarding experience, i.e., on the registration of these services in the EOSC Portal [6]. Section 2 starts with a short overview of EOSC in order to give an insight to the initiative, the landscape. In Section 3 the EOSC onboarding process is described and the NEANIAS implementation is summarised. Section 4 provides details about the onboarding experiences of the 4 NEANIAS thematic services, while Section 5 pulls together the main lessons learnt from the activity.
