Revision	Date	Message	Files
301802 (current)	2025-08-19	Add cross-references to PubChem compounds in COD range 2/10 Each referenced PubChem compound corresponds to the full crystal structure.	2104189.cif
201972	2017-10-13	cif/ Marking COD entries in range 2/10 that are known to be related to ChemSpider entries using the _cod_related_entry data loop.	2104189.cif
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.	2104189.cif
91933	2013-12-28	cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs.	2104189.cif
32112	2012-02-03	cif/: committing an update of 45+ thous files, with information appended from the originals.	2104189.cif
26848	2011-09-28	cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree.	2104189.cif
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).	2104189.cif
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.	2104189.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.	2104189.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.	2104189.cif
903	2009-11-23	cif/ Setting svn:keywords property on those CIFs that did not have them.	2104189.cif
607	2009-03-28	Adding CIFs from the Acta-Cryst-B-2008_05-06/ deposition.	2104189.cif
