The Digital Product Passport requires access to all relevant data as well as the“semantic interconnection”of this data within a company. In addition, interconnection with external data from suppliers and partners is also necessary. This interoperability— which also supports the exchange of digital twins—can be achieved through the use of the open Asset Administration Shell standard (IEC 63278-1). Furthermore, full interoperability requires seamless integration with existing business processes and models within the company—for example, in product engineering and model-based system engineering—as well as the orchestration of relationships at the data, model, and process levels. Model-based methods and descriptions (BPMN 2.0, SysML v2, AutoML, LLM, Predictive Maintenance) are already in use in many areas of the enterprise. The complete interconnection of these complex relationships and aspects can be achieved using a semantic enterprise model based on web standards (W3C), thereby contributing to further value creation within the company.
