Crystallographic Information Framework

From Online Dictionary of Crystallography

Jump to: navigation, search



A system of standards and specifications for the standardised exchange and archiving of crystallographic data built upon, but not restricted to, the Crystallographic Information File.

In addition to file formats, the framework includes formal relations between specific data items expressed in a machine-readable Dictionary definition language, controlled vocabularies, constraints on allowable values of certain numeric data, and procedures for validating the self-consistency of a crystal structure model.

Responsibility for the maintenance of the standard is vested in COMCIFS, a Committee of the International Union of Crystallography.
