The Focus Group OAV Architectures is working on identifying a service architecture that allows the creation of new services and workflows that can be shared within the community in a multi-domain fashion with a corresponding orchestration process.
This should result with potential candidate architecture(s) to be used as a blueprint for a common framework upon which the community can develop solutions (or automated agents) that can be orchestrated in a potentially multi-domain environment.
In order to select suitable architecture candidates that could fit the community needs, the OAV FG investigates available architectures that aim to solve all or some of the aspects of OAV. The group then identifies commonalities in terms of module functionalities, APIs and data models and performs a deep dive analysis. This work is followed by a cross comparison with existing proprietary solutions in the community and may enable harmonisation in the multi-domain environment. The work of the FG also involves continuous monitoring of architectures and new solutions as they become available.
Ultimate goal: to provide benefits to the community for the development and implementation on future single and multi-domain digital services.
