|---|---|---|---|
| 301829 (current) | 2025-08-20 | Add cross-references to PubChem compounds in COD range 4/06/ Each referenced PubChem compound corresponds to the full crystal structure. |
4062611.cif |
| 178522 | 2016-03-21 | cif/4/06/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 4/06/26. |
4062611.cif |
| 120677 | 2014-07-23 | cod/ (saulius@koala.ibt.lt) Adding 4906 DOIs identified by CodBot. |
4062611.cif |
| 34330 | 2012-02-24 | cif/4/ Reorganising CIF range 4 into a prefix tree. |
4062611.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. |
4062611.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. |
4062611.cif |
| 19 | 2008-01-26 | Changing all end-of-line codes from DOS style to UNIX style in all COD CIF files, for more convenient processing: In the cod/cif/ directory: ff \*.cif | xargs perl -i -pe 's/\r\n/\n/' |
4062611.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
4062611.cif |
| 13 | 2008-01-13 | Setting the svn:keywords property to "Author Date Revision URL Id" for all CIF files in the cod/cif directory. |
4062611.cif |
| 1 | 2007-11-30 | Adding all .cif files from the COD, downloaded in a Cod.zip file on 2007.02.07 (and the same Cod.zip is downloadable today, on 2007.11.29) |
