Maeo: An ontology for modeling agents, experts and expertise within an open online materials modeling marketplace

Thiswork describes theMAEOontology, which models agents, experts, expertise and knowledge providers in general within the context of an online, open marketplace for materials modeling and related collaboration activities. Such a marketplace is meant as a one-stop shop for enabling and accelerating materials modeling in industry, and is currently under development within the Horizon 2020 "Market- Place" project. The MAEO ontology has been developed as the underlying basis for the online platform provided by the project, where users may look for experts with a certain expertise, and the latter may subscribe and be made visible and searchable by the users. As it stands, the MAEO ontology is part of a larger effort of ontological modeling for the Materials Modeling area having the EMMO (European Materials Modeling Ontology) as its root, and as such can be seen as an EMMO-based, application-level ontology. This work thus details the ontology's domain, purpose and structure, and underlines the connection with external ontologies, while also providing a brief description of its usage and technical implementation.
