201973 (current)	2017-10-13	cif/2/ Marking COD entries in range 2/20 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	2200467.cif 2200467.hkl
180924	2016-04-02	hkl/2/20/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20/04.	2200467.cif 2200467.hkl
176774	2016-02-20	cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20.	2200467.cif 2200467.hkl
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 {}'	2200467.cif 2200467.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2200467.cif 2200467.hkl
88064	2013-08-29	Adding _cod_database_fobs_code data item to all COD CIFs that have Fobs deposited and did not have this data item yet.	2200467.cif 2200467.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2200467.cif 2200467.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2200467.cif 2200467.hkl
26029	2011-09-17	cif/2/ Reverting changes of revision 25271: ( cd cif/2/; svn merge -r25271:25270 . ) The problem was that the reprocessed files from IUCr, although were more complete, "resurrected" data errors that were corrected in the previous recisions. The additional data that have been extracted during the reprocessing will have to be merged without overwriting the existing values in COD files, except some explicit and controlled cases (such as publication titles and chemical names).	2200467.cif 2200467.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2200467.cif 2200467.hkl
25271	2011-09-10	cif/2/ Adding reporocessed IUCr CIFs for the years 1980-2010. The CIFs now contain more complete bibliography, substance names, correctly unfolded text fields (using the CIF line unfolding protocol), explicitely set cell angles, and _cod_data_source_block fields.	2200467.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.	2200467.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.	2200467.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/'	2200467.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	2200467.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.	2200467.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)	2200467.cif
