The AAS, based on the definition according to IEC 6327816, was developed as an interoperable standard for managing and exchanging the digital twin of any asset over its life cycle. The AAS data is stored in information models, known as submodels. These can be defined for your own application; however, standardization makes sense in terms of interoperable use. This necessary standardization of information models is currently taking place within the Industria Digital Twin Association (IDTA)17. Submodels that have already been standardized include the type plate, technical data and documentation as well as the management of live data. The AAS is therefore also suitable for holding DPP data, which is why DPP4.0, which is being driven forward by ZVEI in Germany, is also based on the AAS.18
As the AAS for industrial components is already being rolled out19, it will provide an ideal basis in future for enriching information in the BIM model and keeping it up to date throughout the life cycle. This applies to product data and changes to specifications as well as to the software used (subject of updates) and access to IOT data. Another interesting aspect is the possibility of collaborative cooperation in the planning phase of buildings, in which data from machines to be installed must be compared with the construction. Examples of coordination include floor loads, movement and safety spaces, media supply, noise and waste heat. An initiative between buildingSMART International and IDTA is currently active to create an interoperable standard for the interaction between IFC and AAS.20
