Setting up a generic workflow to support Material Science and Engineering (MSE) experts in ontology design methodologies is challenging. We are addressing this issue by modeling a “process” using an introductory example. The presented process is intentionally a very simple and generally understandable example to abstract the complex aspect of MSE and focuses on the different properties and potential mappings between MSE-related ontologies. Accordingly, five ontologies were selected based on different levels of granularity, generality, structure, and design paradigm. The approach aims to (1) shorten the gap between ontology and domain experts, (2) provide modeling guidelines for domain experts, and (3) provide ontology alignments to adopt and connect experts’ models to existing ontologies. Furthermore, this straightforward example serves very well to demonstrate the strengths and weaknesses of the different underlying design paradigms of these ontologies. The approach was introduced in the “Ontology Playground”, a common working group between Platform MaterialDigital (PMD) and academic projects providing guidance for ontology design and joint development of shared concepts.
