Abstract: Under the DAPHNE4NFDI consortium, RefXAS has evolved as a comprehensive open-access database for X-ray absorption spectroscopy (XAS). We have implemented a platform that allows users to submit raw datasets and associated metadata via a web interface. The database supports automated metadata handling and quality control, ensuring that uploaded data adheres to predefined standards. Recent developments include the integration of a standardised download package, improved filtering systems, and the transition to institutional data storage at DESY, alongside future plans to incorporate the NeXus format, enhancing machine learning applications. This paper provides an overview of these advancements and their implications for the XAS community.
