HWoDT Framework: A toolchain to build interoperable Digital Twin Ecosystems

Year: 2025

Type: software-paper

Abstract: Digital Twins are increasingly being applied as a design paradigm to model complex Cyber-Physical Systems. These systems extend beyond the original Digital Twin concept, which focused on the virtualization of individual standalone physical assets in vertical application stacks. The interconnected nature of physical environments foresees in Digital Twin Ecosystems a novel abstraction to represent multiple connected Digital Twins of heterogeneous assets. In this paper, we present a toolchain to support the development of Digital Twin Ecosystems based on Web standards and principles, to provide a uniform interface and tackle the heterogeneous nature of Digital Twins. • The HWoDT Framework is an open-source toolchain to support the development of Digital Twin Ecosystems. • Digital Twins developed with heterogeneous technologies can be integrated within the same Ecosystem. • Digital Twins expose a RESTful interface and semantic descriptions. • The WoDT Platform enables to leverage services across the Ecosystem.
