The CEN (European Committee for Standardization) Workshop Agreement CWA 17284 “Materials modelling – terminology, classification and metadata” described in an earlier post has been published. Here is the Abstract:
This CWA includes definitions of fundamental terms for the field of materials modelling and simulation. Computational materials models in this CWA are understood to be physics-based models. This CWA does not include data-based models. The definitions enable a classification of materials models. Using the entity and physics equation concepts, leads to a relatively small number of distinct materials models replacing the current situation of opacity of materials models and simulations that make the field hard to access for outsiders. This CWA also provides a systematic description and documentation of simulations including the user case, model, solver and post-processor: the “materials MOdelling DAta” (MODA). This document seeks to organize the information so that even complex simulation workflows can be conveyed more easily and key data about the models, solvers and post-processors and their implementation can be captured. A template MODA for physics-based models is described in order to guide users towards a complete documentation of material and process simulations. The CWA is based on the Review of Materials Modelling (RoMM). A MODA for data-based models can be found in the RoMM.
This document provides the basis for moving the materials modelling field up the semantic spectrum, laying the foundation for knowledge organisation achieved in many other fields (see e.g. the Osthus presentation “From Big Data to Big Analysis” given at the EMMC Workshop on Interoperability in Materials Modelling). It lays the foundation for developing and ontology of materials modelling, enabling interoperability, reasoning and knowledge extraction in the materials science domain.
Following the proposal by a group of European scientists involved in materials modelling CEN (the European Committee for Standardization) has announced a new workshop on the subject “Materials modelling terminology, classification and metadata”. It is based on many years of effort led by the European Commission and the European Materials Modelling Council (EMMC), as expressed in the Review of Materials Modelling (RoMM), which will be released in its sixth edition in January 2017. The aim is to agree on a terminology and classification of materials models and organise the description of materials modelling applications based on a system referred to as MODA (Materials Modelling Data). A common terminology in materials modelling should lead to simplified and much more efficient communication and lower the barrier to utilising materials modelling. The end result is the adoption of a CEN Workshop Agreement (CWA), a best practices document for further standardisation efforts and input for the development of a future certification scheme.
