Summary and Outlook

This document specifies the interfaces for a single Asset Administration Shell and its Submodels, as well as for a repository of Asset Administration Shells. Additionally, infrastructural interfaces like Registry and Discovery of a set of Asset Administration Shells are specified.

All interfaces are specified in a technology-neutral way before defining technology-specific APIs.

In this version of the specification, HTTP/REST APIs are defined and mapped to the technology-neutral specification as a frontrunner.

In subsequent versions of this specification, APIs using other technologies are planned to be supported, e.g. gRPC or MQTT.

Additionally, further interfaces, service specifications, and profiles may be defined. Querying will also be a topic.
