130149 (current)	2015-01-27	cod/ (saulius@kolibris) Deriving Hall space group symbols for 12003 CIFs using the 'cif_filter --estimate-spacegroup' command.	4000135.cif
130086	2015-01-23	cod/ (robertas@burundukas) The 'cif_fix_values' program was applied to CIFs that have generated the validation messages containing tag '_exptl_crystal_density_meas'. 16946 CIFs had a values that were perceived as 'not measured' and they were changed to '?'. The total of 17089 CIFs was changed. Those that were not corrected by 'cif_fix_values' were reformatted by the parser (e.g. a doi tag was moved to another place). The processing command was: mysql -u cod_reader -h www.crystallography.net cod -e \ 'select distinct codid from validation \ where message like \ "%tag%_exptl_crystal_density_meas'\''%"' -NB \ \| xargs -i sh -c 'cif_fix_values {} \ \| cif_filter --add-cif-header {} \ \| sponge {}'	4000135.cif
34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4000135.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.	4000135.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.	4000135.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/'	4000135.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	4000135.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.	4000135.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)	4000135.cif
