Version of the mmCIF dictionary has been approved by the IUCr body which
oversees
dictionary development and maintenance.   The latest version of the
dictionary 
and other information related can be found at
http://ndbserver.rutgers.edu/mmcif
or one of the mirrors of this site.

Although the content of the versoin 1.0 dictionary is considered stable,
the mmCIF 
dictionary is being actively developed.   The planned evolution and
maintenance 
of the dictionary is described at 
http://ndbserver.rutgers.edu/mmcif/dict-templates/extending.html.

Most of our work has employed  GNU flex and bison or hand written 
parsers.  We have also used the PCCTS tools developed by 
Terence Parr.
