I worry about including the mime_type in the CIF. I feel that the DOI is a permanent reference to some associated data, but that the format could change. As an example DOI might reference a pdf this year, but might move to some other document format in future. > loop_ > _journal_sup_material_id > _journal_sup_material_role > _journal_sup_material_mime_type > _journal_sup_material_doi > > 1 cif chemical/x-cif 10.1107/S0108768110051050/wh5011sup1.cif > 2 hkl text/plain > 10.1107/S0108768110051050/wh5011Pbar1sup2.hkl > 3 hkl text/plain 10.1107/S0108768110051050/wh5011P21csup3.hkl > 4 rtv text/plain > 10.1107/S0108768110051050/wh5011Pbar1sup4.rtv > 5 rtv text/plain 10.1107/S0108768110051050/wh5011P21csup5.rtv > 6 extra application/pdf 10.1107/S0108768110051050/wh5011sup6.pdf I agree that expecting authors to fill out all of this data correctly is probably wishful thinking. The existing CIF 1.1 author name and address loop already appears to present quite a challenge! Some of the later presented data appear to me to belong more to a publication system than a general format for crystal structure experimental output, and that this might be extending things too far. I can see the benefit within a particular journal system. Matt LEGAL NOTICE Unless expressly stated otherwise, information contained in this message is confidential.
