A well-established standard file structure for the archiving and distribution of crystallographic information, CIF is in regular use for reporting crystal structure determinations to Acta Crystallographica and other journals.
Sponsored by the International Union of Crystallography, the current standard dates from 1997. As of July 2011, a new version of the CIF standard is under consideration.
A study-data oriented model, primarily in support of the ICAT data managment infrastructure software. The CSMD is designed to support data collected within a large-scale facility’s scientific workflow; however the model is also designed to be generic across scientific disciplines.
Sponsored by the Science and Technologies Facilities Council, the latest full specification available is v 4.0, from 2013.
NeXus is an international standard for the storage and exchange of neutron, x-ray, and muon experiment data. The structure of NeXus files is extremely flexible, allowing the storage of both simple data sets, such as a single data array and its axes, and highly complex data and their associated metadata, such as measurements on a multi-component instrument or numerical simulations. NeXus is built on top of the container format HDF5, and adds domain-specific rules for organizing data within HDF5 files in addition to a dictionary of well-defined domain-specific field names.
