Towards integrated data control for digital twins in industry 4.0
The Digital Twin is currently a widely discussed topic for presenting and exchanging information on physical assets through vir- tual networks. Especially the digitisation of the manufacturing industry, Industry 4.0, drives the implementation of Digital Twins as part of inte- grated production processes. Hence, the protection of sensitive data be- comes an evident challenge. We contribute by determining the require- ments of current scenarios, the descriptive expressiveness of necessary vocabularies, and by formalising the involved operations. The Asset Ad- ministration Shell is used as a concrete metamodel for Digital Twins and is combined with the data sovereignty and enforcement concepts of the International Data Spaces to illustrate how these concepts can be implemented into a comprehensive Industry 4.0 scenario.
