180880 (current)	2016-04-02	hkl/2/10/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/10/20.	2102030.cif 2102030.hkl
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.	2102030.cif 2102030.hkl
106285	2014-03-15	cod/ (saulius@kolibris) Adding the '_diffrn_radiation_probe neutron' data item to those COD CIFs that declared neuron radiation in their _diffrn_radiation_type data field, and did not have a _diffrn_radiation_probe item yet: codsql 'select file from data where radiation is null and radType like "%neutron%"' -NB \ \| codid2file \ \| xargs -i sh -c 'test -f {} && ( set -x; echo _diffrn_radiation_probe neutron >> {} )' Two files that had no newlines at the end were fixed manually.	2102030.cif 2102030.hkl
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2102030.cif 2102030.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.	2102030.cif 2102030.hkl
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2102030.cif 2102030.hkl
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2102030.cif 2102030.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).	2102030.cif 2102030.hkl
26025	2011-09-16	hkl/2/ Adding assigned Fobs files for the 1980-2010 IUCr data.	2102030.cif 2102030.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.	2102030.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.	2102030.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.	2102030.cif
340	2008-04-05	Fixing CIF files headers in the CIF files from the Acta-Cryst-B/ retrospecive deposition.	2102030.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.	2102030.cif
