Osmo: Ontology for simulation, modelling, and optimization

This work describes the ontology OSMO, i.e., an ontologization and extension of MODA, a work.ow metadata standard that constitutes a mandatory requirement within a number of European calls and projects in the context of materials modelling. OSMO was developed within the Horizon 2020 project VIMMP (Virtual Materials Marketplace) and is part of a larger e.ort in ontology engineering driven by the European Materials Modelling Council, with the Elementary Multiperspective Material Ontology (EMMO) as its core. As such, OSMO provides connections and alignments with other related domain ontologies in computational engineering, including theEMMOitself. Thiswork summarizes the domain, purpose, and design choices underlying OSMO, commenting on the implementation of OSMO and its applications.
