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.	7150488.cif
180290	2016-03-26	cif/7/15/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/15/04.	7150488.cif
120443	2014-07-15	Adding 17924 DOIs guessed from source file names.	7150488.cif
35909	2012-02-26	cif/7/: reorganising range 7 into a prefix-directory tree.	7150488.cif
11752	2011-02-18	cif/7/ Redepositing RSC CIFs that were formally processed with an old version of cif_fix_values script.	7150488.cif
3898	2010-12-09	cif/ Adding the files from the 2004-2000-RSC/ processing directory identified for redeposition. Last page numbers were restored manually from the command line.	7150488.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.	7150488.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.	7150488.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/'	7150488.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	7150488.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.	7150488.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)	7150488.cif
