The drive to more complex SAS experiments, larger data volumes, and
requirements for open data and data repositories calls for standardised,
community-based approaches to data interchange. Enabling automated,
traceable, data processing analysis workflows requires rich metadata to
enhance the usability of the scattering data itself.
Advancing these aims, and building on shared community experience,
canSAS (www.cansas.org) are pleased to announce the next generation
small-angle scattering reduced data storage format: NXcanSAS.
The format, employing NeXus structured HDF5 files, allows for the
storage of reduced small-angle scattering data of multiple dimension.
Supporting a wide range of metadata, and a flexible description of both
uncertainties and resolution information, the format is user-extensible
and capable of storing data from any small-angle scattering beamline.
NXcanSAS is implemented fully in Mantid, DAWN, and SasView. Software
using HDF5 libraries can read and write NXcanSAS.
