Title: Communicating X-rays Spectroscopy Data: Data formats for better, larger, XAS Databases
Abstract
X-ray Absorption Spectroscopy (XAS) gives unique information about the chemical state of materials. High-quality XAS data requires well-prepared samples and access to valuable synchrotron beamlines or state-of-the-art laboratory sources, XAS data is a rare and valuable commodity. Well-maintained databases of XAS spectra on both standard reference materials and samples then become important for the synchrotron and scientific communities, both for individual researchers and for automated machine-learning methods. Enabling the automated use of spectral libraries requires curated and documented formats and metadata fields for the spectral data. I will present existing XAS spectral libraries and formats, and report on progress from a Working Group from the XAFS community towards standardizing metadata and defining specifications for both plain text and NeXuS/HDF5 formats for XAS data.
