210179 (current)	2018-08-27	cif/4/30/ Updating bibliography in entries 4300318-4300321, 4300961-4300964, 4308800. Marking entries 4300318-4300321 as duplicates of entries 4300961-4300964. Marking entry 4308800 as a duplicate of entry 4300964.	4300961.cif
179047	2016-03-22	cif/4/30/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/30/09.	4300961.cif
120081	2014-07-12	Adding DOIs to range 4/30 structures.	4300961.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4300961.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.	4300961.cif
1523	2010-09-25	cif/{1,4} Updating unambiguously identified Inorg. Chem. 2005 structures from the recent Web deposition. Corrdinates of the sructures are not changed, only the bibliograpy and crystallographic information has been updated.	4300961.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.	4300961.cif
853	2009-11-16	cif/ Reconstructing spacegroup designators from the symmetry operators were possible. The comands used can be found in the log file reformat-spacegroups-2009.11.14.log committed with the current revision. Only lines that contained spacegroup designators were changed, and all files pass vcif test after the conversion.	4300961.cif
19	2008-01-26	Changing all end-of-line codes from DOS style to UNIX style in all COD CIF files, for more convenient processing: In the cod/cif/ directory: ff \*.cif \| xargs perl -i -pe 's/\r\n/\n/'	4300961.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	4300961.cif
13	2008-01-13	Setting the svn:keywords property to "Author Date Revision URL Id" for all CIF files in the cod/cif directory.	4300961.cif
1	2007-11-30	Adding all .cif files from the COD, downloaded in a Cod.zip file on 2007.02.07 (and the same Cod.zip is downloadable today, on 2007.11.29)	4300961.cif
