Protein Data Bank in Europe : mmCIF Information

mmCIF is a flexible and extensible tag-value format for representing macromolecular structural data. The set of mmCIF tags, which determine the classes of information present in a given mmCIF format file, are defined in an mmCIF dictionary. The structure of the dictionary is in turn defined by a ddl. The standard mmCIF dictionary - now stable since being ratified by the IUCr in 1997 - was pioneered by Paula M. Fitzgerald, Helen Berman, Phil Bourne, Brian McMahon, Keith Watenpaugh, and John Westbrook. However, work is still ongoing fine-tuning dictionary extensions. More information on mmCIF can be found at the mmCIF Resource pages at the RCSB.
