Towards Data Format Standardization for X-ray Absorption Spectroscopy



Bruce D. Ravel, J. R. Hester, V. A. Sole, M. Newville


A working group on data format standardization for X-ray Absorption Spectroscopy has recently formed under the auspices of International X-ray Absorption Society and the XAFS Commission of the IUCr. This group of beamline scientists and XAS ractitioners has been tasked to propose data format standards to meet the needs of the world-wide XAS community. In this report, we present concepts for addressing three XAS data storage needs, a single spectrum interchange format, a hierarchical format for multispectral X-ray experiment, and a relational database format for XAS data libraries.
