This document presents the last architectural blueprint for the interTwin Digital Twin Engine (DTE), detailing its functional specifications, requirements analysis, and components. The blueprint guides the technical Work Packages (WPs) within the interTwin project, ensuring alignment with associated subsystem requirements. Furthermore, it integrates insights from related initiatives and projects to identify architectural components that can be adopted within the interTwin framework. This blueprint acts as the definitive conceptual model for the DTE.
