283960 (current)	2023-05-23	cif/9/ (saulius@tasmanijos-velnias) Estimating atom types and attached hydrogen counts for all range 9 COD entries. Atom types and hydrogen counts for about 170 entries were adjusted manually after running 'cif_guess_AMCSD_atom_types'. Commiting only those entries where declared and calculated summary formulae are matching exactly. To get the reduced formula, the Z value was estimated with 'cif_estimate_Z' after atom type adjustment. NB.: some files still do not contain the Z value, since the Z that was written into the files was estimated before the atom type correction was made, not after. The Z values will be recomputed once more after the atom types are checked in.	9012665.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.	9012665.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.	9012665.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.	9012665.cif
120115	2014-07-12	Adding DOIs to range 9 structures.	9012665.cif
85285	2013-05-05	cod/ (saulius@koala.ibt.lt) Removing outdated _amcsd_database_code data items from all series 9 CIFs.	9012665.cif
35913	2012-02-28	cif/9/ Reorganising range 9 into a prefix-directory tree. Range 9 is the last range to be reorganised.	9012665.cif
1210	2010-06-10	cif/9/ Updating 13213 AMCSD CIFs, taking new data from the AMCSD database and adding the assigned AMCSD numbers.	9012665.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/.	9012665.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.	9012665.cif
903	2009-11-23	cif/ Setting svn:keywords property on those CIFs that did not have them.	9012665.cif
649	2009-04-18	Depositing new CIFs from AMCSD-resynchronisation-2009.03.27/.	9012665.cif
