|---|---|---|---|
| 282548 (current) | 2023-04-10 | cif/ Removed the '_amcsd_database_code' data item from multiple entries since the values were outdated and no longer relevant. |
2016825.cif 2016825.hkl |
| 282068 | 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. |
2016825.cif 2016825.hkl |
| 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. |
2016825.cif 2016825.hkl |
| 180837 | 2016-04-02 | cif/2/01/ (antanas@echidna) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/01/68. |
2016825.cif 2016825.hkl |
| 176760 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/01. |
2016825.cif 2016825.hkl |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2016825.cif 2016825.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. | 2016825.cif 2016825.hkl |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2016825.cif 2016825.hkl |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2016825.cif 2016825.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). |
2016825.cif 2016825.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. |
2016825.cif 2016825.hkl |
| 1212 | 2010-06-10 | cif/ Inserting AMCSD numbers for the automatically recognised series 1, 2, 4, 5 and 8 CIFs. |
2016825.cif 2016825.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. |
2016825.cif 2016825.hkl |
| 903 | 2009-11-23 | cif/ Setting svn:keywords property on those CIFs that did not have them. |
2016825.cif 2016825.hkl |
| 697 | 2009-05-05 | Adding 1667 more Fobs files, ones that have cell constans differenig not more than 0.1% from the cell constants in the coordinate file. The symmetry operators must also match in both files. |
2016825.cif 2016825.hkl |
| 601 | 2009-03-27 | Adding CIFs deposited from Acta-Cryst-C-2008_09-12/. |
