The Colloquium is entitled “Communicating X-rays Spectroscopy Data: Data formats for better, larger, XAS Databases” and will dive deeper into the use and variety of XAS data.
XAS: Samples, Synchrotron Access, and Data Management
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.
Application example presented by Matthew Newville
The Speaker Matthew Newville will provide insights 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.
