Zusammenfassung
The challenges posed by climate change can only be met by changing the economic mindset to one that focuses on the idea of a circular economy
(CE). Digitalization, data collection and data storage play a crucial role here: Product-related data should be collected in a consistent manner
throughout the entire life cycle of the product and stored in a Digital Product Passport (DPP). The DPP should give all stakeholders of the CE
access to the necessary data. Overarching modelling is required to ensure that a DPP can be used as a structure across application domains in
an interoperable way. Ontologies can act as an interlingua between domains, incorporating the required domain knowledge and the full range of
requirements for the DPP. Following a modular approach based on Ontology Design Patterns, this paper develops a DPP ontology with a focus
on the R-strategies within the CE. Furthermore, the paper builds a bridge to the standardized approach of Industry 4.0, the modelling and storage
of structured domain knowledge in Asset Administration Shells (AAS). Data can be seamlessly integrated and used for decision-making in each
product life cycle phase. In addition, the reuse of existing concepts defined by others is demonstrated. The developed ontology is then evaluated
on a CE use case.
