D4.1: Architecture and Specifications for the Digital System

The architecture is developed from system use cases and functional and non-functional requirements, which are mapped to the components responsible for implementing them. It distinguishes data acquisition, virtualisation and integration, decision-support services, knowledge exchange and user interaction. DAMS supplies harmonised data, while the digital-twin environment represents value chains and mediates service interactions. Product passports support traceability, and modelling, assessment and configuration services provide decision support. The layered specification defines interaction patterns so that these components can be integrated progressively around the needs and data of the pilots.

Project planning and methodological framework.

The specification connects data acquisition, energy management, virtualisation, orchestration and product passports with simulation, assessment, configuration, AI, knowledge exchange and citizen-engagement services. It provides the architectural basis for later implementation and integration evidence.

Architecture and interface specifications describe the intended system. Deployment and integration progress are covered by later implementation reports.
