Am I in Good Shape? Flexible Way to Validate Asset Administration Shell Data Entry via Shapes Constraint Language

Digital Twins and their adoption in Industry 4.0 are trending topics. Asset Administration Shell (AAS) has been introduced as a standard metamodel and application programming interface (API) to cope with interoperability issues. The specification discusses possibilities of serializing the AAS meta-model to various formats such as XML, JSON, and RDF. It also introduced various schemas to check the compliance of serialized content with the specification. In this paper, we show that Shapes Constraint Language (SHACL) is not only possible to be used for schema compliance checks but also for data entry validation. Within our use case, we show the flexibility of our solution, which is also platform independent.
