| 201982 | 2017-10-13 | cif/ Marking COD entries in range 4 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
4021792.cif |
| 178395 | 2016-03-21 | cif/4/02/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/02/17. |
4021792.cif |
| 120074 | 2014-07-11 | Adding DOIs to range 4/02 structures. | 4021792.cif |
| 34330 | 2012-02-24 | cif/4/ Reorganising CIF range 4 into a prefix tree. |
4021792.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. |
4021792.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. |
