| 176768 | 2016-02-20 | cif/2/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 2/10. |
2103267.cif 2103267.hkl |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2103267.cif 2103267.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. | 2103267.cif 2103267.hkl |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2103267.cif 2103267.hkl |
| 31984 | 2012-01-04 | cif/ Changing data item '_diffrn_standards_decay_% negligible' to '_diffrn_standards_decay_% 0'. |
2103267.cif 2103267.hkl |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2103267.cif 2103267.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). |
2103267.cif 2103267.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. |
2103267.cif 2103267.hkl |
| 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. |
2103267.cif 2103267.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. |
2103267.cif 2103267.hkl |
| 691 | 2009-05-03 | Depositing the first portion of the Fobs data CIFs. These are CIFs from the Acta Cryst. journals, where the correspondence of the coordinate CIF and the Fobs CIF could be unambiguously determined automatically. In these files, cell constatnts match exctely, being equal with the floating point '==' operator in Perl. For the future depositions, such requirement is too strict, since sometimes cell constants in the coordinate and the Fobs files differ by a rounding error. Thus, a small tollerance will have to be introduced into the COD Fobs deposition scripts. |
2103267.cif 2103267.hkl |
| 380 | 2008-06-11 | Adding new deposition of the Acta-Cryst-B-2002/ CIF files. |
