Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.
Information models are created in a decentralized setup and the specific benefits are demonstrated by means of use cases. The aim is to make the Asset Administration Shell a standard as the technical base for Industrial Digital Twins. The Asset Administration Shell (AAS) is the standardized digital representation of the asset, corner stone of the interoperability between the applications managing the manufacturing systems. AAS identifies the Administration Shell and the assets represented by it, holds digital models of various aspects (submodels) and describes technical functionality exposed by the Administration Shell or respective assets [Source: AAS Spec Part 1]. Core elements of AAS are the metamodels, APIs and security.
Eclipse AAS Web Client develops and implements a viewer for the Asset Administration Shell models and its published interfaces. As the specifications of the AAS are continuously being further developed, the Eclipse AAS Web Client has to be adapted to the new interfaces and model extensions, as well as new parts e.g., authentication of users and secure transfer of information.
The Eclipse Foundation provides a professional environment (governance, licensing, intellectual property management) for the future development of Eclipse AAS Web Client. These advantages facilitate the usage of an open source, extensible ecosystem in which manufacturers and suppliers including the providers of applications, platforms, and infrastructure, can all participate equally.
There is a project repository originally hosted at admin-shell-io (https://github.com/admin-shell-io) implementing the Asset Administration Shell that is considered as initial contribution to this project:
web-aas-client: This project provides a viewer for Asset Administration Shells, which can be used client-side - https://github.com/admin-shell-io/web-aas-client
For this project we use Eclipse AAS Web Client instead of web-aas-client at GITHUB admin-shell-io.
Eclipse AAS Web Client and its involved parties intend to move to Eclipse as soon as possible. We hope to have the initial migration of the existing GITHUB repo done until February 2022.
Eclipse AAS Web Client wants to build an open-source community in Eclipse in order to coordinate the building of an extensible ecosystem in which manufacturers and suppliers, including the providers of applications, platforms and infrastructure, can all participate equally.
There will be close relationships to other open-source projects building upon the Asset Administration Shell standards, e.g., Eclipse AASX Package Explorer, Eclipse BaSyx.
