Digital Twin in Industrial Application – Requirements to a Comprehensive Data Model form the practical foundation for our pro- posals. Sections 4 and 5 present our conclu- sions in terms of the contents and behavior of digital twin models. These give rise to sug- gestions about how to realize such digital twin models, which we present in section 6, and we conclude with an examination of the outlook for the future (section 7). the core concept of an “asset” and describes the following aspects: D ATA M ODELS FOR D IGITAL T WINS At least one crucial use case for the digital twin data model mentioned above takes the form of information exchange between part- ners in the supply chain, e.g. between “sup- pliers” and “integrators.”     Probably one of the best-known data models for digital twins is the “Asset Administration Shell” as formulated by Plattform Industrie 4.0. In short, this model is structured around Identification and description of an asset Submodels related to this asset Property definitions to specify data from operations Access Control Figure 1: Meta-model of Asset Administration Shell (Plattform Industrie 4.0) IIC Journal of Innovation - 95 -
