Powder CIF dictionaryThe powder CIF dictionary (pdCIF) is a supplement to the Core dictionary addressing the needs of powder diffractionists. While the goal of the initial CIF effort was to define a file format to contain information typically found in a single-crystal structure manuscript (and supplementary materials), the powder CIF effort had the additional goals of documenting and archiving experimental data. It is intended that powder CIF be used for communication of completed studies, but also for data exchange between laboratories. This is frequently done at shared diffraction facilities such as neutron and synchrotron sources. The powder dictionary was written anticipating needs from conventional X-ray diffractometers, as well as from synchrotron, CW neutron, TOF neutron, and energy dispersive X-ray instruments
