180364 (current)	2016-03-26	cif/7/20/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/20/33.	7203368.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"	7203368.cif
120435	2014-07-15	cif/ (saulius@koala.ibt.lt) Restoring full bibliographies for the 310 COD entries with recently added DOIs (DOIs were generated automatically from the source file names). Mnay (most? all?) of these entries will probably be duplicates of later added ones, so this needs to be checked extra.	7203368.cif
120433	2014-07-15	cif/ (saulius@koala.ibt.lt) Correcting bibliographies and inserting DOIs for 310 COD entries that had bibliographies wrong, apparently because of the bug in the COD depositions system of the time when they were deposited (the bug is fixed since then; the buggy deposition system would take bibliographies from the previous deposited entry if the bibliography for a new entry wa missing). The DOIs for these entries were restored by synthesising them from the source file names.	7203368.cif
35909	2012-02-26	cif/7/: reorganising range 7 into a prefix-directory tree.	7203368.cif
11752	2011-02-18	cif/7/ Redepositing RSC CIFs that were formally processed with an old version of cif_fix_values script.	7203368.cif
5312	2011-01-03	cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version.	7203368.cif
1504	2010-09-08	cif/7/ Adding data extracted from RSC 2005 and 2006 year publications.	7203368.cif
