202018 (current)	2017-10-14	cif/ Marking COD entries in range 8 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	8101427.cif
176728	2016-02-18	cif/ (antanas@echidna.ibt.lt) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 8.	8101427.cif
102498	2014-02-20	cif/8/10/ (antanas@lokys.ibt.lt) Adding bibliographic information: issue, first page, last page.	8101427.cif
100393	2014-02-05	cif/8/10/ (antanas@lokys.ibt.lt) Adding issue and volume numbers. Fixing author name.	8101427.cif
35911	2012-02-28	cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree.	8101427.cif
5310	2011-01-02	cif/ Running cif_fix_enum with the core CIF dictionary on COD ranges 2, 8 and 9. Range 9 remained unchanged, and in ranges 2 and 8 there were 17309 modified files, most changes were fixes enumerator case.	8101427.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.	8101427.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.	8101427.cif
23	2008-01-27	Removed characters with the high-bit set from all COD CIF files, using the following commands: ff \*.cif \ \| xargs -n1 perl -ne 'print $ARGV,"\n" and last if /[\177-\377]/' \ \| tee have-high-bit-chars.lst cat have-high-bit-chars.lst \ \| xargs -t -n1 -iI sh -c 'iconv -f latin1 I \ \| utf8-to-cif \ \| perl -pe "s//\\\\/g" \ \| fold -w 79 -s > I.tmp; mv I.tmp I' Afterwards, some file were corrected manually, to remove one remaining \177 character, and to fix single-quoted lines that became too long and were folded.	8101427.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/'	8101427.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	8101427.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.	8101427.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)	8101427.cif
