Semantic communication between components for smart factories based on oneM2M

The digital transformation across the whole value chain in the industry is aiming at increasing the overall efficiency of production services. In this context the Operational Technology (OT) and the Information and Communication Technology (ICT) domains grow together to an Industrial Internet of Things (IIoT). Interconnecting heterogeneous assets and services with each other that have typically not communicated before, arise multiple challenges. In order to enable physical assets to mutually negotiate the production process, they can be encapsulated by software components to form Cyber-Physical Systems (CPSs). However, how related Asset Administration Shells (AASs) will be implemented, is not yet defined in detail. While a number of approaches are under discussion, we assume that in the end exchanged information needs to be interoperable on a semantic level. In this paper, we argue that the oneM2M standard offers the required functionalities by allowing the use of Semantic Web technologies to formally describe interactions and exchanged information. We have started to validate our idea by extending an existing implementation in this regard. The main goal of this paper is to contribute towards a semantically interoperable IIoT vision that spans multiple vertical domains.
