132410	2015-02-25	cod/ (robertas@burundukas) Replaced zero-length value of the tag '_chemical_name_systematic' with '?'. codsql 'select file, chemname from data \ where length(chemname) = 0' -NB \ \| perl -ne 'print $1."\n" if /\b(\d{7})\s$/' \ \| codid2file \ \| xargs perl -0777 -i -pe 's/\b_chemical_name_systematic \K \s?

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"	2203223.cif 2203223.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2203223.cif 2203223.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.	2203223.cif 2203223.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2203223.cif 2203223.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2203223.cif 2203223.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).	2203223.cif 2203223.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2203223.cif 2203223.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.	2203223.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.	2203223.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.	2203223.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.	2203223.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.	2203223.cif
30	2008-01-27	Adding the reprocessed files from my first COD deposition. Reprocessing with the new cif-tools scripts removed missing tags and added Acta Cryst. Coeditor codes into those files where the corresponding CIF tag was present. Not all reprocessed files were changed. Alsin two entries, cif/8/8000061.cif and cif/8/8000065.cif, were removed manually, both from the CIF file directory and from the cif2cod.txt file, since these two files were detected to be duplicates.	2203223.cif
20	2008-01-26	Removing white space at the end of all lines from all COD CIF files: in the cod/cif/ directory: ff \*.cif \| xargs perl -i -pe 's/\s+\n$/\n/'	2203223.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	2203223.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.	2203223.cif
5	2008-01-03	Adding 507 CIF files deposited into COD today, on 2008.01.03.	2203223.cif
