The EU project OSCARS (Open Science Clusters’ Action for Research and Society) brings research data to new audiences and targets new use-cases in a broad range of scientific clusters including Photon and Neutron Sciences (PaN). As recommended by a new White Paper from the user organisations, ESUO and ENSA, adherence to the FAIR principles (Findable, Accessible, Interoperable, Reusable) facilitates the use of research data in novel ways, with increased citations acknowledging original researchers and facilities that provided that data. Further, increased (meta)data and software findability and accessibility promotes a better use of resources by reducing the duplication of experiments.

We recently completed the task of consolidating the achievements of the PaN Open Science Cluster (PaNOSC), integrating knowledge and skills from various contexts to create a more comprehensive understanding. This was achieved by cataloguing existing resources to gain an overview of available services and data sources. For PaNOSC, we created the portfolio from scratch, starting with collections from key Research Infrastructures (RIs). Representatives from various RIs within PaNOSC, established under OSCARS, significantly contributed by adding new resources and updating information on existing ones, resulting in a portfolio of over 500 resources. The services and data sources identified are candidates for being on-boarded to the thematic PaNOSC EOSC node, which has been selected for implementation in the EOSC Federation.

The portfolio serves as a foundation for identifying services needed for specific tasks within typical research scenarios. We have gathered a selection of PaNOSC-typical scenarios that can be streamlined and enhanced by composing the relevant services. We will highlight several key aspects of these scenarios that show high potential for composability. One or two of these aspects will be developed as demonstrators within the project, while others will be addressed through the OSCARS Open Call funded projects.
