| Revision | Date | Message | Files |
|---|---|---|---|
| 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(current) | 2023-04-10 | cif/ Removed the '_amcsd_database_code' data item from multiple entries since the values were outdated and no longer relevant. |
2013916.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. |
2013916.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. |
2013916.cif |
| 176432 | 2016-02-14 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries. |
2013916.cif |
| 106285 | 2014-03-15 | cod/ (saulius@kolibris) Adding the '_diffrn_radiation_probe neutron' data item to those COD CIFs that declared neuron radiation in their _diffrn_radiation_type data field, and did not have a _diffrn_radiation_probe item yet: codsql 'select file from data where radiation is null and radType like "%neutron%"' -NB \ | codid2file \ | xargs -i sh -c 'test -f {} && ( set -x; echo _diffrn_radiation_probe neutron >> {} )' Two files that had no newlines at the end were fixed manually. |
2013916.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2013916.cif |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2013916.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2013916.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). |
2013916.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. |
2013916.cif |
| 1212 | 2010-06-10 | cif/ Inserting AMCSD numbers for the automatically recognised series 1, 2, 4, 5 and 8 CIFs. |
2013916.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. |
2013916.cif |
| 853 | 2009-11-16 | cif/ Reconstructing spacegroup designators from the symmetry operators were possible. The comands used can be found in the log file reformat-spacegroups-2009.11.14.log committed with the current revision. Only lines that contained spacegroup designators were changed, and all files pass vcif test after the conversion. |
2013916.cif |
| 19 | 2008-01-26 | Changing all end-of-line codes from DOS style to UNIX style in all COD CIF files, for more convenient processing: In the cod/cif/ directory: ff \*.cif | xargs perl -i -pe 's/\r\n/\n/' |
2013916.cif |
| 14 | 2008-01-14 | Appending a header with SVN keywords, COD URL and copying policy to all COD CIF files. |
2013916.cif |
| 13 | 2008-01-13 | Setting the svn:keywords property to "Author Date Revision URL Id" for all CIF files in the cod/cif directory. |
2013916.cif |
| 1 | 2007-11-30 | Adding all .cif files from the COD, downloaded in a Cod.zip file on 2007.02.07 (and the same Cod.zip is downloadable today, on 2007.11.29) |
