301837 (current)	2025-08-21	Add cross-references to PubChem compounds in COD range 4/31/ Each referenced PubChem compound corresponds to the full crystal structure.	4317661.cif
288252	2023-12-12	cif/ Corrected misspelt data names in multiple entries using the 'cif_correct_tags' program and a data name replacement file from cod-tools revision 9842. This change affected only the misspelt variants of the '_diffrn_measurement_device_type' data name.	4317661.cif
211332	2018-10-05	cif/ Fixing enumeration values for CIF data items _atom_sites_solution_* using cif_fix_values. Data item relocations and exclusion of CIF comment lines might have occurred due to the usage of cif_filter.	4317661.cif
176467	2016-02-16	cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 4.	4317661.cif
130086	2015-01-23	cod/ (robertas@burundukas) The 'cif_fix_values' program was applied to CIFs that have generated the validation messages containing tag '_exptl_crystal_density_meas'. 16946 CIFs had a values that were perceived as 'not measured' and they were changed to '?'. The total of 17089 CIFs was changed. Those that were not corrected by 'cif_fix_values' were reformatted by the parser (e.g. a doi tag was moved to another place). The processing command was: mysql -u cod_reader -h www.crystallography.net cod -e \ 'select distinct codid from validation \ where message like \ "%tag%_exptl_crystal_density_meas'\''%"' -NB \ \| xargs -i sh -c 'cif_fix_values {} \ \| cif_filter --add-cif-header {} \ \| sponge {}'	4317661.cif
120093	2014-07-12	Adding DOIs to range 4/31 structures.	4317661.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4317661.cif
17004	2011-03-31	cif/ Commiting CIFs, that were updated with the 'cif_fix_values' script, using options '--fix-misspelled replacement_values.lst', '--fix-temperature' and '--fix-enums' with built-in table of enum values. The following cmd was used: > (set -x; find ? -name \*.cif \| sort \| xargs -i sh -c 'if !( > cif_fix_values --fix-misspelled ~/../inputs/replacament_values.lst {} \| > cif_filter --add-cif-header {} \| > sponge {} ) 2>&1 \| grep NOTE; then svn revert {}; > fi' ) &	4317661.cif
