201972 (current)	2017-10-13	cif/ Marking COD entries in range 2/10 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	2102151.cif
191977	2017-02-10	cif/2/ (antanas@echidna.ibt.lt) Changing the _atom_site_occupancy data item value from '.' to '1' for all fully occupied atom sites in entries 2001195, 2001620, 2001711, 2001834, 2001901, 2003209, 2003210, 2003355, 2003856, 2004107, 2004584, 2004635, 2004830, 2005050, 2005777, 2006097, 2006230, 2007115, 2007405, 2007420, 2007566, 2007907, 2007988, 2008006, 2008387, 2008586, 2009295, 2009401, 2009405, 2009474, 2009792, 2009955, 2010239, 2010323, 2010479, 2010480, 2010647, 2010753, 2010754, 2010831, 2010832, 2011145, 2011503, 2012300, 2012403, 2014174, 2102151.	2102151.cif
176768	2016-02-20	cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/10.	2102151.cif
134621	2015-04-02	The 'cif_fix_values' script with an option '--fix-only-weighting-scheme' and 'cif_filter' script were run over CIF files which included an incorrect value of the data item '_refine_ls_weighting_scheme'. Read the log for more details. There were more than 18k CIF files with values to modify. Usually these incorrect values include comment with formulas, but values of this data item must be an enumerator. The script creates new data item '_refine_ls_weighting_details' to store these comments with formulas, and writes the enumerator 'calc' as a value of data item '_refine_ls_weighting_scheme'. There exists some exceptions in the script.	2102151.cif
129439	2015-01-07	cod/ (robertas@burundukas) Correcting values of _exptl_crystal_density_meas and _exptl_crystal_density_method data items: codsql "select codid from validation where message like '%\\'_exptl_crystal_density_meas\\' value \"not measured\" is %'" -NB \ \| codid2file \ \| xargs perl -i -pe "s/_exptl_crystal_density_meas\\s+'not +measured'/_exptl_crystal_density_meas ?/i; \ s/_exptl_crystal_density_method\\s+('not +measured'\|\\?\|none)/_exptl_crystal_density_method ./i"	2102151.cif
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2102151.cif
86227	2013-05-10	smi/1 Adding SMILES for boranes, metalocenes, metal carbonyls and others in subdir 1	2102151.cif
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2102151.cif
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2102151.cif
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).	2102151.cif
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.	2102151.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.	2102151.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.	2102151.cif
785	2009-07-05	cif/: Fixing 6 CIFs where _atom_site_thermal_displace_type and _atom_site_occupancy were juxtaposed, or where _atom_site_occupancy was missing but listed in the _atom_site_[] loop instead of _atom_site_adp_type.	2102151.cif
340	2008-04-05	Fixing CIF files headers in the CIF files from the Acta-Cryst-B/ retrospecive deposition.	2102151.cif
326	2008-04-03	Adding all Acta Cryst. B, C, and E missing retrospective CIF files up to 2008 February, generated from the files that were automatically downloaded from the IUCr site.	2102151.cif
