Store information on how a result (e.g. Young's modulus) has been obtained

[joergfunger]

The Youngs modulus in our workflow is the result of a processing step that depends on further information, e.g. in our test there might be an Youngs modulus according to the standard (even in this case we would have to document the script that is used in order to make it reproducible), or according to a Bayesian inference procedure (where information related to prior, likelihood, sampler, burn in, ..) has to be stored. This results in the requirement of actually having not a single deterministic Youngs modulus stored in the ontology, but rather a set of Youngs moduli (with metadata allowing to distinguish these results).
