Dear COMCIFS members, On 2013-07-17 13:44, yayahjb wrote: > _IUCR::atom_site.occupancy > as equivalent to > _atom_site.occupancy > when the discipline is know to be IUCR If I correctly understand the current namespace proposal and its suggested enhancements, the datablock like: data_1 _audit.discipline SAXS _refine_ls_goodness_of_fit_all 1.01 #end_data_1 would mean that, for the sake of example, the '_refine_ls_goodness_of_fit' is defined in the discipline (aka namespace) "SAXS", would be described in a dictionary different from the cif_core.dic, and might have different type, constraints and meaning from the data item described in cif_core.dic? I so, I see a bit of a problem if the '_audit.discipline' gets lost at some stage (and the practice shows data items do get lost, for one reason or another ;). In such case, the '_refine_ls_goodness_of_fit_all 1.01' data item will be mis-interpreted as stemming from the IUCr discipline. This might be a minor annoyance for CIFs used as processing intermediates, but and unpleasant headache for archive-stored data. In general, if the new mechanism encourage the use of the same data names for different purposes in different disciplines, an ambiguity will arise if the _audit.discipline tag is lost or not provided. And given the current situation with the _audit_conform_dict_*, this could be quite likely. Do you think this is a serious problem? The current prefix-based mechanism is immune to the _audit_* tag loss -- one can always figure out, with some work, the dictionaries that describe _pdbx_ or _cod_ tags.
