The following automatic conversions were performed:

data name '_chemical_melting_point' was changed to
'_chemical_melting_point_gt' since the value was specified as 'more
than' ('>') a certain temperature.

data item '_symmetry_cell_setting' value 'Monoclinic' was changed to
'monoclinic' in accordance with the
/home/saulius/struct/COD-crude-data/automatic-downloads/DataCite-retrospective/ACS/depositions/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 last updated on
