Summary and Outlook

This document has defined the metamodel for the structural viewpoint of the Asset Administration Shell using the technology-neutral modelling language UML.

Several serializations and mappings are offered for the Asset Administration Shell based on this specification:

  • XML, mainly used for file exchange between partners via the exchange format .aasx,

  • JSON, mainly used for API definition, but also for file exchange as alternative to XML, and

  • RDF for reasoning.

Additional parts of the document series cover (see [37]):

  • interfaces and APIs for accessing the information of Asset Administration Shells (access, modify, query, and execute information and active functionality), Part 2; the payload of these APIs is based on the definitions of the information model in this document, Part 1,

  • predefined data specification templates (Part 3 series), for example for concept descriptions of properties conformant to IEC61360 (Part 3a),

  • the infrastructure, which hosts and interconnects multiple Asset Administration Shells, implementing registry, discovery services, endpoint handling, and more,

  • security aspects including access control, Part 4.
