Query: XrdML, a new way to store (and exchange) X-ray powder diffraction
  measurement data   Recently PANalytical introduced the XrdML file format as a new data platform
for powder diffraction experiments. We will explain why an industrial standard
(XML) was chosen and show the XML schema used to precisely describe the
instrumental and experimental conditions. This schema is used to validate the
contents of the XrdML files. Additionally the integration of the XrdML files
with the MS Windows operating system and the MS Windows Explorer will be
demonstrated.
