- The project pillars, represented by individual software tools, are interconnected and integrated into the BDSS platform. The interoperability layer will also seek compatibility with platforms from other BDSS projects, by contributing and adhering to the European Materials Modelling Ontology (EMMO) metadata and interoperability standard emerging via the collaboration within the context of the European Materials Modelling Council. The integration of different existing software solutions by means of an interoperability and metadata layer allows for carrying out multidisciplinary/multi-objective optimisation and analytics for material and process evaluation, uncertainty management and selection, spanning through “cradle-to-grave” lifetime of a product.
Interoperability involves the development of an effective approach for materials information management across modelling and experiment, materials modelling integration and communication including reference standards and standardised methods for the representation, storage and communication of models. It also supports knowledge management of models and workflows, a key feature for business systems and value chain interactions. Proper definition of interfaces, data structures, schemas and associated metadata is a prerequisite to guarantee interoperability among different materials modelling components as well as to support knowledge management across materials modelling data, business data, or LCE models. The BDSS platform overcomes the incompatibility in existing components by i) developing and implementing a “unified data and model representation architecture” using abstract classes defining common generic interfaces, and ii) using metadata schemas to facilitate semantic interoperability. This effort includes i) designing and implementing metadata schemas and Application Programming Interfaces (API) for materials and processes models and ii) designing and developing case study specific templates for materials modelling workflow chains, allowing to replace individual commercial/open-source codes in materials modelling. The metadata schemas for materials and processes models are being developed in order to describe also materials and related business and LCE data. This will lead to a rigorous quantification of all levels of materials structure in a large number of distinct material configurations, a repository for materials data and source of input data for materials modelling.
The BDSS integrates materials modelling, business tools and databases by following a well-defined ISO standard business process format. The business layer will be based on two well-defined standards: BPMN 2.0, the last version of the Business Process Model Notation standard defined by the Object Management Group (OMG), ISO standard ISO/IEC 19510:2013, and the DMN, the Decision Making Notation standard, also defined by the OMG. The use of a standard representation (ISO standard ISO/IEC 19510:2013) and the Decision Model and Notations (DMN) for business processes will make available the decision-making strategy across the different sectors and users. The BDSS could be connected with any third party platform. The developed workflows in MuPIF are software components defining documented interface enabling to set input parameters, execute workflows and query outputs, thus allowing integration into other integration platforms.
