202017 (current)	2017-10-14	cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	7150349.cif
180289	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 7/15/03.	7150349.cif
120443	2014-07-15	Adding 17924 DOIs guessed from source file names.	7150349.cif
35909	2012-02-26	cif/7/: reorganising range 7 into a prefix-directory tree.	7150349.cif
11752	2011-02-18	cif/7/ Redepositing RSC CIFs that were formally processed with an old version of cif_fix_values script.	7150349.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.	7150349.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.	7150349.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.	7150349.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/'	7150349.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	7150349.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.	7150349.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)	7150349.cif
