211332 (current)	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.	4309315.cif
179131	2016-03-23	cif/4/30/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/30/93.	4309315.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 {}'	4309315.cif
120081	2014-07-12	Adding DOIs to range 4/30 structures.	4309315.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4309315.cif
5312	2011-01-03	cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version.	4309315.cif
1526	2010-09-26	cif/4/ Adding new CIFs from Inorg. Chem. 2005 deposited via Web deposition site to the COD test database (and transferede to the main COD database after renaming).	4309315.cif
