CIF dictionaries

Describes CIF, the data exchange standard of crystallography. Provides: information for scientists who wish to record or use the results of a single-crystal or powder diffraction experiment; the data ontology necessary for designing interoperable computer applications; accompanying software including machine-readable CIF dictionaries, libraries and utility programs.

An essential guide and reference to CIF for programmers, data managers handling crystal-structure information and practising crystallographers.
