Ontopanel: A Tool for Domain Experts Facilitating Visual Ontology Development and Mapping for FAIR Data Sharing in Materials Testing

Abstract In recent years, the design and development of materials are strongly interconnected with digital technologies. this respect, efficient data management is building block material digitization and, in field science engineering (MSE), effective solutions for standardization sharing different resources needed. Therefore, ontologies applied that represent a map MSE concepts relationships between them. Among ontology approaches, graphical editing based on standard conceptual modeling languages increasingly used due to its intuitiveness simplicity. This approach also adopted by Materials-open-Laboratory project (Mat-o-Lab), which aims develop domain method graphs accordance testing standards MSE. To suit actual demands experts project, Ontopanel was created as plugin popular open-source editor diagrams.net enable editing. It includes set pipeline tools foster diagrams.net, comprising imports reusage ontologies, converting diagrams Web Ontology Language (OWL), verifying using OWL rules, mapping data. reduces learning costs eliminating need switch various tools.
