Digital Product Passport and Interoperability

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.

Semantic Web

The Semantic Web represents a stage in the evolution of the World Wide Web. It extends the Web to make published information and data machine-readable, exchangeable, and usable. The information is assigned unique meanings and supplemented with additional details so that both humans and machines can recognize the meaning, context, and other relationships within the information (the semantics).

The Semantic Web is based on knowledge modeling or knowledge representation (for a specific knowledge domain).

Tim Berners-Lee (founder of the World Wide Web) described his proposal in 2001 as follows:“The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work together.”
