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.	2204471.cif 2204471.hkl
180964	2016-04-03	hkl/2/20/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20/44.	2204471.cif 2204471.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.	2204471.cif 2204471.hkl
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"	2204471.cif 2204471.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2204471.cif 2204471.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.	2204471.cif 2204471.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2204471.cif 2204471.hkl
31986	2012-01-04	cif/ Changing more tags to match the dictionary specifications: -_diffrn_standards_interval_count none -_diffrn_standards_interval_time none -_diffrn_standards_number none +_diffrn_standards_interval_count 0 +_diffrn_standards_interval_time . +_diffrn_standards_number 0	2204471.cif 2204471.hkl
31984	2012-01-04	cif/ Changing data item '_diffrn_standards_decay_% negligible' to '_diffrn_standards_decay_% 0'.	2204471.cif 2204471.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2204471.cif 2204471.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).	2204471.cif 2204471.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2204471.cif 2204471.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.	2204471.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.	2204471.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.	2204471.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.	2204471.cif
321	2008-03-30	Changing the COD CIF files header (comments) in all files that were recently deposited from the IUCr autodownloaded sources to the text agreed with IUCr.	2204471.cif
101	2008-02-08	Renaming the '_[local]_cod_original_file' tag into '_[local]_cod_data_source_file'. This reflects better the actual usage of the mentioned files -- they were used for data extraction, but not as originals for verbatim copying.	2204471.cif
87	2008-02-04	Adding CIF files from ActaE2004-Issues-4-12/ (1465 files).	2204471.cif
