Shared Digital Twin – using data as a strategic resource
(only in German)
The Shared Digital Twin was developed based on the RIOTANA IoT architecture created by Fraunhofer ISST. With RIOTANA, informative performance figures can be generated from the raw data of ongoing processes (such as vibrations, temperature, or friction) in real time. The administration shell standardized by the industry 4.0 platform is used as the digital twin, so the framework and interfaces of the twin are clearly defined and uniform.
Shared however means that the data do not remain only in the company but are exchanged in network structures. Here the solution uses IDS connectors promoted by Fraunhofer and numerous industry partners within the framework of the International Data Spaces (IDS) initiative, with the goal of enabling the standardized, sovereign exchange of data between various companies. By using International Data Spaces, control of the data is always retained by the company that provides the data by attaching usage policies to the data that are shared with cooperation partners. Both companies that share the digital twin can also enrich the data with information.
Thus the Shared Digital Twin with the administration shell and IDS connectors is based on two standards that are already being used by industry. What database is used in the twin can be decided according to the respective use case.
