You should not base production software on this dictionary until
it has been properly reviewed and accepted by the community and
approved by COMCIFS.

This is the beginning of a 45 day comment period that will end
on Friday, 18 August 2006.  Please send your comments to this
list (imgcif-l at iucr.org) or to me by email.  We can discuss
as much as we have on hand at the imgCIF workshop (WK.02) at
the 2006 ACA summer meeting in Hawaii on 22 July 2006.  If major
changes are needed, we can always start another comment period.
When we achieve a draft that has community support with only
minor revisions, it will be forwarded to COMCIFS.

   The cumulative changes in this draft are summarized below.

     Regards,
       Herbert J. Bernstein

The changes from the last official release (1.3.2) are as follows:

     1.4     2005-07-04

;  This is a change to reintegrate all changes made in the course of
     publication of ITVG, by the RCSB from April 2005 through
     August 2008 and changes for the 2006 imgCIF workshop in
     Hawaii.

     2006-07-04 Consolidated changes for the 2006 imgCIF workshop 
(edited by HJB)
       + Correct type of '_array_structure_list.direction' from 'int' to 'code'.
       + Added new data items suggested by CN
         '_diffrn_data_frame.details'
         '_array_intensities.pixel_fast_bin_size',
         '_array_intensities.pixel_slow_bin_size and
         '_array_intensities.pixel_binning_method
       + Added deprecated item for completeness
         '_diffrn_frame_data.details'
       + Added entry for missing item in contents list
         '_array_structure_list_axis.displacement'
       + Added new MIME type X-BASE32K based on work by VL, KM, GD, HJB
       + Correct description of MIME boundary delimiter to start in
         column 1.
       + General cleanup of text fields to conform to changes for ITVG
         by removing empty lines at start and finish of text field.
       + Amend example for ARRAY_INTENSITIES to include binning.
       + Add local copy of type specification (as 'code') for all children
         of '_diffrn.id'.
       + For consistency, change all references to 'pi' to '\p' and all
         references to 'Angstroms' to '\%Angstroms'.
       + Clean up all powers to use IUCr convention of '^power^', as in
         '10^3^' for '10**3'.
       + Update 'yyyy-mm-dd' type regex to allow truncation from the right
         and improve comments to explain handling of related mmCIF
         'yyyy-mm-dd:hh:mm' type, and use of 'Z' for GMT time zone.

     2005-03-08 and
     2004-08-08 fixed cases where _item_units.code  used
                instead of _item_type.code (JDW)
     2004-04-15 fixed item ordering in
                 _diffrn_measurement_axis.measurement_id
                 added sub_category 'vector' (JDW)
;
