Uncertainty support in the spectral information System SPECCHIO

The spectral information system SPECCHIO was updated to support the generic handling of uncertainty information in the form of uncertainty tree diagrams. The updates involve changes to the relations database model as well as dedicated methods provided by the SPECCHIO application programming interface. A case study selected from classic field spectroscopy demonstrates the use of the functionality. In conclusion, a database-centric automated uncertainty propagation in combination with measurement protocol standardization will provide a crucial step toward spectroscopy data accompanied by propagated, traceable, uncertainty information
