Specification of the Asset Administration Shell Part 1: Metamodel – IDTA Number: 01001-3-0

The aim of this document is to define selected specifications of the structure of the Administration Shell to enable the meaningful exchange of information about assets and I4.0 components between partners in a value creation network.

This part of the document focuses on how such information needs to be processed and structured. In order to define these specifications, the document formally stipulates some structural principles of the Administration Shell. This part does not describe technical interfaces of the Administration Shell or other systems to exchange information, protocols, or interaction patterns.

This document focuses on:

• a metamodel for specifying information of an Asset Administration Shell and its submodels,
• exchange format for the transport of information from one partner in the value chain to the next,
• identifiers,
• access control,
• an introduction to the need of mappings to suitable technologies used in different life cycle phases of a product: XML, JSON, RDF, AutomationML, and OPC UA.
