Details of the Asset Administration Shell - Part 2 Interoperability at Runtime – Exchanging Information via Application Programming Interfaces (Version 1.0RC02)
Introduction
This part extends Part 1 and defines how information provided in the Asset Administration Shell (AAS) (e.g. submodels or properties) can be accessed dynamically via Application Programming Interfaces (APIs).

The publication also describes some infrastructure services: Asset Administration Shells are registered or register themselves and can be easily searched and found without having to know on which server a AAS is hosted.
