|---|---|---|---|
| 180113 (current) | 2016-03-26 | cif/7/10/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/10/11. |
7101106.cif |
| 120443 | 2014-07-15 | Adding 17924 DOIs guessed from source file names. | 7101106.cif |
| 91955 | 2013-12-31 | cod/ (saulius@koala.ibt.lt) Removing '_journal_page_first ?' data items from a bunch of COD CIFs so that the quastion mark does not appear in the COD SQL tables as a page number. |
7101106.cif |
| 35909 | 2012-02-26 | cif/7/: reorganising range 7 into a prefix-directory tree. | 7101106.cif |
| 5312 | 2011-01-03 | cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version. |
7101106.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. |
7101106.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. |
7101106.cif |
| 231 | 2008-03-04 | Adding CIF files generated from the Chem-Comm-2005-1_5/ input files. |
