CDIF-4-XAS: OSCARS Project on InteroperabilityAuthors: Abraham Nieva de la Hidalga, Arofan Gregory, Heike Goerzig, Leandro Liborio,Markus Kubin, Patrick Austin, Rolf Krahl, Simon Hodson, Vyacheslav TykhonovX-ray Absorption Spectroscopy (XAS) research has expanded to become a set of widely used scientificmethods with applications across Physics, Chemistry, Surface Science, Nanoscale Science, Biology, andEnvironmental and Earth Sciences. Over time, various scientific communities, research facilities, deviceproviders, and software developers have created different formats and applications to store XAS dataand describe it with metadata. These custom data formats are very often developed ad-hoc they servetheir immediate needs and they are integrated with local workflows but they are not easily integratedor interoperable outside their immediate usage. While some standards such as XAFS Data Interchange(XDI) format and NeXus HDF5 format have been developed, add-hoc formats are a widely implementedand practical interoperability across the full range of systems has yet to be realized. This project looksat using the WorldFAIR Cross-Domain Interoperability Framework (CDIF), in combination with existingdomain standards and ontologies, to show that real interoperability can be achieved. CDIF utilizescommon cross-domain standards such as Schema.org, SKOS, and DDI-CDI to support FAIR exchange ofdata. The project includes drafting the CDIF profile and mappings from existing standards, andimplementation of CDIF tools and workflows inside the EOSC Galaxy infrastructure, including the use ofgenerative AI to enhance metadata capture. This presentation will present the profile and mappings anddiscuss how this approach may be applied to other use cases. We will also discuss and demo theimplementation in Galaxy and the wider applicability of these solutions.
