# XDI Data Format¶

The data here use the plain-text file format defined by the XAS-community known as the XAFS Data Interchange Format or XDI. This format has been designed to describe a single XAS spectrum in a way that conveys all the important information needed to work with and understand that spectrum. A detailed description of this format can be found at https://github.com/XraySpectroscopy/XAS-Data-Interchange/blob/master/specification/spec.md and example data files can be found in this collection or at https://github.com/XraySpectroscopy/XAS-Data-Interchange/tree/master/data.

To import data into this library, the data must be in the XAS-Data-Interchange (XDI) format, and must have a file extension of .xdi.
