We define interoperability as the ability of two or more systems to exchange information through a common representational system to perform complex tasks that cannot be done by each single system alone.

The common representational system provides the highest level of generalisation leading to a range of benefits including

  • No privileged one-to-one connection between systems is required nor desired
  • Linear scaling of interoperability operations as more systems are added, rather than power scaling for one-to-one compatible systems.

Agreement on a common representational system also facilitates standardisation of computational interfaces as well as standardisation of documentation, based on underpinning metadata, taxonomies and ontologies.

  • Standardisation of interfaces
  • Standardisation of data documentation facilitated by agreement on the common representational system


  • Awareness raising, highlighting the benefits and impact of interoperability and widely agreed terminology, taxonomy and ontology standards.
  • Supporting and governing the development of the European Materials & Modelling Ontology (EMMO) as a foundation for interoperability.
  • Making materials models and related data more accessible and usable to industry by means of a range of actions such as
    • Supporting and coordinating standardised data documentation
    • Supporting and coordinating the development of systems and applications based on interoperability standards, e.g. Open Simulation Platforms
