European Materials & Modelling Ontology (EMMO) EMMO is a multidisciplinary effort to develop a standard representational framework (the ontology) based on current materials modelling knowledge, including physical sciences, analytical philosophy and information and communication technologies. It provides the connection between the physical world, materials characterisation world and materials modelling world.
