277875 (current)	2022-09-15	cif/ Added space group information derived from the space group operation list using the 'cif_filter' program.	8000006.cif
211175	2018-09-26	cif/ Removing _chemical_name_systematic and _chemical_name_common data items with placeholder values from 513 entries in range 8.	8000006.cif
120070	2014-07-11	cif/ (saulius@koala.ibt.lt) Adding DOIs for structures in ranges 5, 6 and 8.	8000006.cif
35911	2012-02-28	cif/ Reorganising ranges 1, 3, 5, 6 and 8 into a prefix-directory tree.	8000006.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.	8000006.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.	8000006.cif
907	2009-11-23	cif/ Correcting unquoted string values starting with '['. The list of such COD entries was obtained from the PyCifRW parser error log: grep === ~/tests/pycifrw/all-cod-parse-errors.log \ \| awk '{print $2}' \ \| xargs perl -i -lpe "s/^(\s)_(.)(\s+)\[(.*)\$/\$1_\$2\$3'[\$4'/" The resulting entries were checked with 'vcif', 'cif_filter' (uses our CIFParser) and PyCifRW: svn st \| grep ^M \| awk '{print $NF}' \| sort \| xargs -n1 vcif -l 2048 svn st \| grep ^M \| awk '{print $NF}' \| sort \| xargs -n1 cif_filter > /dev/null svn st $(pwd) \ \| grep ^M \ \| awk '{print $NF}' \ \| sort \ \| xargs -n1 -iX sh -c 'cd ~/tests/pycifrw/; set -x; ./cif_reader.py X' No errors were found.	8000006.cif
21	2008-01-26	Replacing all my collected files in COD with a newly regenerated CIF files that now have correct syntax.	8000006.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/'	8000006.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	8000006.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.	8000006.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)	8000006.cif
