| 282068 (current) | 2023-03-26 | cod/ (saulius@tasmanijos-velnias) Adding the '_cod_related_entry_...' loop to those COD AMCSD entries that lacked it, and adding the related AMCSD database ID to this loop. |
2207681.cif |
| 282053 | 2023-03-24 | cod/ (saulius@tasmanijos-velnias) Updating the existing COD records from the recent AMCSD downloads: - Adding AMCSD IDs to those COD records that exacly matched the AMCSD structures (comparing unit cells, space groups, coordinates and measurement conditions) but did not yet have the AMCSD ID; - Adding new mineral names, compound sources, measurement conditions (when those were missing) and other informations from the AMCSD CIFs. |
2207681.cif |
| 277834 | 2022-09-14 | cif/ Added space group information derived from the space group operation list using the 'cif_filter' program. |
2207681.cif |
| 176774 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/20. |
2207681.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2207681.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2207681.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. |
2207681.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. |
