Description
To support the principles of FAIR data, the Small Angle Scattering Biological Data Base (SASBDB) serves as a platform to make biological SAXS and SANS data more accessible and findable [1]. Within the SASBDB framework, experimental data can be deposited alongside relevant experimental conditions, sample details, and instrument characteristics, ensuring comprehensive documentation for future reuse [2].
Using SASBDB as a benchmark, we identified essential metadata and information required to properly deposit entries in such a database. While some beamlines are already designed to save important metadata during data collection, many smaller or laboratory X-ray sources lack automated metadata recording, resulting in raw detector images being stored without crucial sample or instrument information. To address this challenge, we introduce a standardized metadata catalogue related to BioSAXS experiments, along with a method for sample identification using the generation of an International Generic Sample Number (IGSN). We present a use case specific workflow scheme that includes the creation of a Nexus file as an additional step that incorporates metadata and IGSN information in a standardized format.
