Dr. Birgit Boss works with Robert Bosch GmbH in different business areas and sectors in an international setting since 1996. She is a Software Engineer and Lead Software Architect with more than 20 years experience in the development and roll out of architectures, methods and standards for complex (embedded) systems. Areas of expertise include Software Architecture, Software Product Line Development, Software Ecosystems, Continuous Refactoring, Process Development and AUTOSAR. Her current interest is on Industrial IoT, semantic technologies and digital twin concepts (including the asset administration shell).

Dr. Birgit Boss is active in various standardization committees and activities in the context of industry 4.0, the AG1 “Reference Architectures, Standards and Norms” of the German Plattform Industrie 4.0, Industrial Internet Consortium (IIC), ZVEI Work Group “Models and Standards”, eCl@ss Digitalization Expert Group and others. She is convinced that standardization is a key factor for interoperability.

Dr. Birgit Boss studied computer science at the TH Darmstadt, Germany. She worked as a research engineer at the Forschungszentrum Informatik (FZI) and received the PH.D. degree from the Karlsruhe University, Germany, in 1995.

The asset administration shell provides an asset abstraction and allows access to the data of the asset via a standardized interface. In this presentation the focus will be on the information model of the asset administration shell. The asset can be described by so-called submodels being composed out of properties, operations and other elements. For interoperability not only the technical type of the data needs to be defined but there is also a need for semantic descriptions of the data.

The information model is specified in a technology neutral way. For different life cycle phases different formats are needed for exchange and (technical) interoperability. The current status of the information model including its derived formats, an xml schema, a JSON serialization as well as an OPC UA mapping will be presented. The main stakeholders for the information model and the derived formats are developers and architects.
