|---|---|---|---|
| 291792 (current) | 2024-05-09 | Inserting Z values into entries of 9 range, mostly missing. |
9010520.cif |
| 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. |
9010520.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. |
9010520.cif |
| 176465 | 2016-02-16 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 9. |
9010520.cif |
| 85285 | 2013-05-05 | cod/ (saulius@koala.ibt.lt) Removing outdated _amcsd_database_code data items from all series 9 CIFs. |
9010520.cif |
| 35913 | 2012-02-28 | cif/9/ Reorganising range 9 into a prefix-directory tree. Range 9 is the last range to be reorganised. |
9010520.cif |
| 1210 | 2010-06-10 | cif/9/ Updating 13213 AMCSD CIFs, taking new data from the AMCSD database and adding the assigned AMCSD numbers. |
9010520.cif |
| 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/. |
9010520.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. |
9010520.cif |
| 903 | 2009-11-23 | cif/ Setting svn:keywords property on those CIFs that did not have them. |
9010520.cif |
