Beschreibung
A variety of near-surface geophysical methods are used to characterise soil properties at agricultural sites. Such data also provide information on archaeological features and soil dynamics. Metadata standards help making data findable, accessible, interoperable, and reusable according to the FAIR principles.
The aim is therefore to develop a metadata standard for near-surface geophysical prospection. This model, developed with the software Protégé, contains method-independent as well as sensor-specific metadata. The terms were classified hierarchically and restrictions were introduced to ensure all the fundamentals being retrieved, and leaving the possibility to add additional information later. Furthermore, data and object properties were defined in order to specify data formats and also to use defined terms from predefined lists. Existing standards were queried in order to achieve uniform use of selected parameters and thus improve the comparability of the data sets described. Based on the newly developed ontology, and the metadata description derived from it, its outcome will later be made available as a tool for data acquisition to enable interchangeability.
The here presented metadata model represents an initial development stage from FAIR-agro use case 14, which is based on a joint initiative within the NFDI (FAIRagro, NFDI4Objects, NFDI4Earth). It comprises method-independent metadata as well as specific models for electromagnetic induction (EMI) and magnetic prospection. In the future, the model will be expanded and adapted according to the needs of the expert community. In addition, the model will be tested on real measurements.
