Abstract
The CEN workshop aims to establish a common language (definitions and vocabulary) for materials characterisation and modelling. It aims to update a previous CEN Workshop Agreement on the same topic. Our work on the Characterisation Methodology Ontology (CHAMEO) will underpin the updates to provide a machine-readable reference for the characterisation terminology and metadata, and a clearer structure to the items that are required for documentation of characterisation experiments and the related data processing. The documentation of materials modelling, which was the topic of another CWA, were also discussed.
