| 282067 | 2023-03-26 | cod/ (saulius@tasmanijos-velnias) Adding AMCSD ID to the '_cod_related_entry_' data loop. |
9012104.cif |
| 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. |

| 202019 | 2017-10-14 | cif/ Marking COD entries in range 9 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
9012104.cif |
| 85285 | 2013-05-05 | cod/ (saulius@koala.ibt.lt) Removing outdated _amcsd_database_code data items from all series 9 CIFs. |
9012104.cif |
| 35913 | 2012-02-28 | cif/9/ Reorganising range 9 into a prefix-directory tree. Range 9 is the last range to be reorganised. |
9012104.cif |
| 20519 | 2011-06-11 | smi/* and cif/* Adding SMILES for all structures with nel=1 in the mysql entries, supossed to be pure elements. For most of them, just the element symbol remains since SMILES strings and substructure search makes no sense for compact packed structures. Only for molecularly defined substances (for example cyclosulphur moieties) a proper SMILES string has been defined. This does not add too much funcionality to substructure search but flags a large number of structures as "SMILES done". Some of them were found to be not pure elements (carbides, boranes, hydrocarbons) but were added anyway. CIF files and SQL entries have been fixed for these as well as for other with obviously wrong formulas. |
9012104.cif |
| 1210 | 2010-06-10 | cif/9/ Updating 13213 AMCSD CIFs, taking new data from the AMCSD database and adding the assigned AMCSD numbers. |

| 1071 | 2010-04-10 | cif/9/ Updating COD entries from AMCSD, processed in the AMCSD-resynchronisation-2009.06.24/ directory. Entries are updated if they could be unambiguously mapped to a unique COD number by automatic search scripts in AMCSD-resynchronisation-2009.06.24/. |
9012104.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. |
