| 201974 (current) | 2017-10-13 | cif/2/ Marking COD entries in range 2/21 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
2218854.cif 2218854.hkl |
| 181108 | 2016-04-03 | hkl/2/21/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/21/88. |

| 176787 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/21. |
2218854.cif 2218854.hkl |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2218854.cif 2218854.hkl |
| 88064 | 2013-08-29 | Adding _cod_database_fobs_code data item to all COD CIFs that have Fobs deposited and did not have this data item yet. | 2218854.cif 2218854.hkl |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2218854.cif 2218854.hkl |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2218854.cif 2218854.hkl |
| 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). |
2218854.cif 2218854.hkl |
| 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. |
2218854.cif 2218854.hkl |
| 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. |
2218854.cif 2218854.hkl |
| 903 | 2009-11-23 | cif/ Setting svn:keywords property on those CIFs that did not have them. |
2218854.cif 2218854.hkl |
| 691 | 2009-05-03 | Depositing the first portion of the Fobs data CIFs. These are CIFs from the Acta Cryst. journals, where the correspondence of the coordinate CIF and the Fobs CIF could be unambiguously determined automatically. In these files, cell constatnts match exctely, being equal with the floating point '==' operator in Perl. For the future depositions, such requirement is too strict, since sometimes cell constants in the coordinate and the Fobs files differ by a rounding error. Thus, a small tollerance will have to be introduced into the COD Fobs deposition scripts. |
2218854.cif 2218854.hkl |
| 450 | 2008-10-01 | Adding changes after the recent Acta-Cryst-E-2008-03-08/ (mostly, inserted the _journal_coeditor_code tags). |
2218854.cif |
| 446 | 2008-09-30 | Adding new CIF files from the Acta-Cryst-E-2008-03-08/ deposition. |
