2103216.cif |
| 199516 | 2017-08-04 | cif/2/10/ (antanas@echidna.ibt.lt) Adding the _cell_formula_units_Z data item in entries 2103164, 2103178, 2103179, 2103181, 2103182, 2103184, 2103185, 2103186, 2103189, 2103190, 2103193, 2103195, 2103199, 2103201, 2103202, 2103208, 2103216, 2103217, 2103220, 2103222, 2103223 after consulting the original publication. |
2103216.cif |
| 176435 | 2016-02-14 | cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries from ranges 1, 2. |
2103216.cif |
| 91933 | 2013-12-28 | cif/ (saulius@koala.ibt.lt) Adding DOIs that could be assigned unambiguously to the range 2x CIFs. |
2103216.cif |
| 32112 | 2012-02-03 | cif/: committing an update of 45+ thous files, with information appended from the originals. | 2103216.cif |
| 26848 | 2011-09-28 | cif/2/, hkl/2/, html/ Reorganising CIFs of the range 2* into the "prefix-directory" tree. |
2103216.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). |
2103216.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. |
2103216.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. |
2103216.cif |
| 380 | 2008-06-11 | Adding new deposition of the Acta-Cryst-B-2002/ CIF files. |
