Schema development workflow. We first conduct requirement analyses as interviews with experts to have a valid foundation for our work. Then, we revise the results and structure the data using user stories (knowledge acquisition). The obtained information is transformed into metadata items and attributes (conceptualisation). In this phase, we additionally integrate reusable ontologies in order to enable interoperability. During the last development step, we serialise the components using RDF(S) and we define SHACL expressions for validation purposes (implementation). The resulting schema is then evaluated in the final step.
