Description
DAPHNE4NFDI, part of Germany’s National Research Data Infrastructure (NFDI), focuses on implementing FAIR principles for research data from Photon and Neutron (PaN) sources at large-scale facilities, universities, and research institutions. This includes the adoption of SampleDB as a flexible metadata solution, with comparisons to alternatives like ICAT and SciCat. Metadata catalogues are categorized into raw data repositories, institutional databases, and public-access systems, each with distinct roles. Key considerations include the integration of standards like NeXus, user-friendly searchability, and metadata enrichment. Case studies, including RefXAS, illustrate practical implementations and quality assessments. The paper also discusses Authentication and Authorization Infrastructure (AAI) strategies for secure, role-based data access, offering recommendations to enhance collaboration, data quality, and a unified, FAIR-compliant metadata ecosystem for the PaN research community.
The objective of this white paper Catalogue is to pinpoint a catalogue solution suitable for DAPHNE4NFDI partners. It aims to identify catalogue use-cases and the expected nature of searches along with outlining the metadata schema. The contents of this document provide a preliminary yet concise specification of (non-)requirements, a review of the current state and local solution landscape, incorporating lessons learned and a discussion leading to preliminary conclusions and decisions.
