## 1 Scope

The companion specification presented in this document is an extension of the overall OPC Unified Architecture standards and defines an information model that conforms to the Industrie 4.0 Asset Administration Shell (AAS) metamodel defined in the Plattform Industrie 4.0 document “Details of the Asset Administration Shell” (see Section 2).

The aim of the AAS metamodel is to enable partners in a value creation network to exchange meaningful information by conforming to a specified set of standardized information elements.

This companion specification describes the mapping of the AAS metamodel specified in “Details of the Asset Administration Shell - Part 1” (see Section 2) to the OPC UA information model in order to represent AAS and their submodels in the address space of OPC UA servers.
