  Semantic interoperability based on the European Materials and Modelling
  Ontology   The European Materials and Modelling Ontology (EMMO) is a top-level ontology
designed by the European Materials Modelling Council to facilitate semantic
interoperability between platforms, models, and tools in computational
molecular engineering, integrated computational materials engineering, and
related applications of materials modelling and characterization. Additionally,
domain ontologies exist based on data technology developments from specific
platforms. The present work discusses the ongoing work on establishing a
European Virtual Marketplace Framework, into which diverse platforms can be
integrated. It addresses common challenges that arise when marketplace-level
domain ontologies are combined with a top-level ontology like the EMMO by
ontology alignment.
