Core CIF Dictionary
The core dictionary is a set of data names designed to cover the
requirements of archiving and exchanging raw and processed data and derived
structural results for single-crystal small-molecule and inorganic crystal
studies.
The working discussions
of the Core Dictionary Maintenance Group, a COMCIFS
subcommittee responsible for the maintenance of the Core dictionary, may be
reviewed for indications of current areas of evolution within the
dictionary.
