The cornerstone of these initiatives should be a process-centric data model, as suggested previously by the General Process Ontology (GPO) . Complementing this is the peripheral, an inventory description that includes machine and material metadata using Battery Interface Ontology (BattINFO) and various data sources and digital assets. This strategic approach can significantly impact integration time, AI application, and closed-loop process/value chain optimization, including recycling. Furthermore, it offers interoperable data for other domains, particularly sustainability research (SSbD).
