Global trends such as mass customization and lot size one, demand flexibility, autonomy and adaptability in production. Interoperability of devices is a key challenge as production systems evolve into Cyber-Physical Production Systems (CPPS). As part of the German strategic project Industrie 4.0 (I4.0), concepts and solutions for continuous digitization of production are being developed, in order to meet these numerous challenges. The concept of the Asset Administration Shell (AAS) was introduced in order to provide data and information in a standardized and semantically described manner, thus enabling interoperability and easy interaction. In this paper, we show how users can translate a semantic description of plants, machines or individual components that are based on a standardized Open Platform Communication Unified Architecture (OPC UA) information model, into the AAS information model.
