|---|---|---|---|
| 249446 (current) | 2020-03-17 | cif/2/ Switching from COD_ERROR to COD_ENTRY_ISSUE CIF data items to describe the issues in a bunch of entries in range 2*. |
2103187.cif |
| 176342 | 2016-02-11 | cif/ (antanas@kurmis) Merging the values of _[local]_cod_depositor_comments and _cod_depositor_comments tags in files where both tags were present. Also, deprecated _[local]_cod_* tags were replaced with their replacement tags. |
2103187.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2103187.cif |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2103187.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2103187.cif |
| 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). |
2103187.cif |
| 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. |
2103187.cif |
| 5310 | 2011-01-02 | cif/ Running cif_fix_enum with the core CIF dictionary on COD ranges 2, 8 and 9. Range 9 remained unchanged, and in ranges 2 and 8 there were 17309 modified files, most changes were fixes enumerator case. |
2103187.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. |
2103187.cif |
| 654 | 2009-04-19 | Fixing incorrect number of loop elements in the entries 2102492.cif and 2103187.cif. |
2103187.cif |
| 380 | 2008-06-11 | Adding new deposition of the Acta-Cryst-B-2002/ CIF files. |
