198633 (current)	2017-07-11	cod/ (melanie@ameba.ibt.lt) Correcting the '_refine_ls_hydrogen_treatment' data item 'constr' enumeration values with the help of the cif_fix_values script from the cod-tools package revision 5455. The following command was used : cif_fix_values --fix-misspelled src/cod-tools/trunk/data/replacement-values/replacement_values.lst $i \| cif_filter --no-exclude-publication-details -h $i \| sponge $i A total of 700 files were changed.	4101579.cif

120076	2014-07-11	Adding DOIs to range 4/10 structures.	4101579.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4101579.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.	4101579.cif
966	2010-01-30	cif/ Adding _cod_database_code tags to all COD entries. Adding tag description to the cif_cod.dic dictionary so that COD entries can be validated.	4101579.cif
396	2008-06-20	Adding new CIF files from J-Am-Chem-Soc-2006/.	4101579.cif
