Description

In computer science, programming patterns are an invaluable source of creating state-of-the-art software. They propel the invention cycle of software projects, providing the vast availability of software solutions. Further, there exists a lot of tools and standards to manage and store data in the big data and AI economies. However, in scientific research structured data modelling patterns are not widely adopted across fields. This often leads to lab-contained data and programming solutions making the reproducibility and interoperability of such data a barely managable task. We aim to provide standardisation for lab-sized data management according to the FAIR principles (findable, accessible, interoperable, reproducible) and show how to take advantage of the NeXus standard. NeXus is a common exchange format for neutron, X-ray, and muon experiments, which us used mainly at large beamline facilities. We adapted generic data modelling patterns to a set of example measurements (for various optical and electrical characterisation methods) and also applied it to NeXus, where we encountered several limitations in representing data collections in a standardised and machine actionable way. Here, we present our solutions to these limitations and offer data patterns to tackle common design patterns in organising data collections and their metadata. Although some of the examples are using the NeXus standard as a specific representation, our approach is not tied to a specific format, and we aim to present generic data modelling strategies. Accordingly, these patterns are for general use, and support making FAIR data management a systematically solvable task.
