180767 (current)	2016-04-02	cif/2/00/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/00/88.	2008843.cif 2008843.hkl
176759	2016-02-19	cif/2/ (antanas@echidna.ibt.lt) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/00.	2008843.cif 2008843.hkl
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.	2008843.cif 2008843.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2008843.cif 2008843.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.	2008843.cif 2008843.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2008843.cif 2008843.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2008843.cif 2008843.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).	2008843.cif 2008843.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2008843.cif 2008843.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.	2008843.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.	2008843.cif
481	2008-11-20	Changing volume number in numerous Acta Cryst. C published CIFs from 'C[0-9]?[0-9]' into '[0-9]?[0-9]'. This makes the COD CIF collection more uniform, and also helps the deposition scripts to spot potential duplicates more accurately. The command for this transformation was: for i in 2/.cif; \ do ( \ if grep -q '_journal_volume C' $i && \ grep -q '_journal_name_full .Acta Cryst' $i; \ then \ echo === $i ===; \ perl -i -pe 's/_journal_volume C/_journal_volume /' $i; \ perl -i -pe \ "s/_journal_name_full ./_journal_name_full 'Acta Crystallographica Section C'/" $i ; \ fi \ ) done	2008843.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/'	2008843.cif
14	2008-01-14	Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files.	2008843.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.	2008843.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)	2008843.cif
