Overview
The Asset Administration Shell (AAS; German Verwaltungsschale) is the standardized digital representation — the "digital twin" interface — of an industrial asset, whether that asset is a product, a component or a machine. It is being standardized as IEC 63278 and specified in detail by the IDTA (Industrial Digital Twin Association).
The AAS is a standard container for an asset's data. It splits that data into submodels (German Teilmodelle) — self-contained, machine-readable blocks that any tool can read because they follow published IDTA templates.
How it is structured
The AAS organizes an asset's data into standardized submodels — self-contained blocks such as the digital nameplate, technical data, documentation, carbon footprint, or a compliance / material submodel. Because each submodel follows a published IDTA template, any tool can read it without bespoke integration.
Why it matters for compliance
The AAS is a leading candidate carrier for the Digital Product Passport and for exchanging material and compliance data inside data spaces — for example, Catena-X uses AAS-based submodels. It is a core building block of Industrie 4.0 / Industry 4.0.
Where standards like IPC-1752A or IEC 62474 standardize a declaration file, the AAS standardizes the whole digital twin that such a material declaration can sit inside as one submodel.
