The Eclipse Arrowhead provides a Service Oriented Architecture-based interoperability and integrability framework for the design and operation of complex systems of systems in the industrial automation domain. Through a service oriented architecture enabling the loose coupling of relevant services, Eclipse Arrowhead provide the concepts and tooling for such a framework. The actual implementation of services relevant for a specific production ready use cases is beyond the scope this project.
The project covers architecture, software systems, and services originated from multiple European and national projects e.g., Arrowhead and Arrowhead Tools , EMC2 , Productive4.0 , FAR-EDGE . The architecture is summarised in multiple papers [5, 6] and a book . The architecture is built on a concept called local clouds [8, 9]. Local clouds are self contained and are populated with at least 3 mandatory core system and a selection of support core systems. Currently available core systems and are:
- Mandatory core systems: Service Registry, Orchestrator, Authorization.
- Supporting core systems: Event Handler, Gateway, Gatekeeper, Translator, QoS Manager, QoS Monitor, DataManager, etc. The currently released support systems and release candidate systems are currently located at https://github.com/arrowhead-f
All these systems and their services are open-source and keep the Eclipse licensing scheme or should be transfered to the Eclipse licensing schema.
On the other hand, legacy application systems or services that have Eclipse Arrowhead compatible APIs, but do not belong the above category - simply do not belong to the scope.
