From Local Digital Twins to the CitiVerse
Promoting the EU Local Digital Twins (LDT) Toolbox, EDIC, SIMPL and the CitiVerse
This special track focuses on the design, deployment and evaluation of interoperable Digital Twins and Data Spaces that enable measurable social good. It emphasizes Local Digital Twins for cities and communities and their interconnection through trusted data sharing, semantic interoperability and open building blocks.
Architectures and reference implementations for city-scale digital twins enabling smarter, more resilient urban systems.
Trusted data sharing, federation, and cross-domain interoperability for smart and sustainable cities and communities.
AI-driven decision-support systems, simulation pipelines, and urban resilience tools grounded in real deployments.
Sovereignty mechanisms, compliance with AI Act, Data Act and GDPR, and ethics in digital twin deployments.
European cities and communities are scaling digital transformation under increasing sustainability, resilience and inclusion pressures. Digital twins are becoming operational decision-support systems, while data spaces are emerging as the backbone for trusted data sharing across public and private actors.
Interoperable digital twins and data spaces support social good by enabling evidence-based policy, climate action, improved public services, transparent governance and citizen participation. This track foregrounds measurable impacts and responsible-by-design practices.
We welcome contributions combining scientific novelty with practical reproducibility, including open-source components, reference architectures, reusable semantic models, governance patterns and impact evaluations.
Architectures and reference implementations for Local Digital Twins and city-scale Digital Twins
Data Spaces for Smart and Sustainable Cities: federation, catalogues, and cross-domain data sharing
Interoperability standards and APIs (NGSI-LD, semantic data models, open specifications)
Trust, identity and sovereignty mechanisms for data exchange (consent, access control, usage policies)
SIMPL-enabled middleware, integration patterns and operational tooling
EDIC-oriented governance and operational models for shared digital infrastructures
CitiVerse and immersive/3D assets as interoperable extensions of city digital twins
Compute-to-data, confidential analytics, and privacy-preserving digital twin pipelines
AI governance and compliance (AI Act, Data Act, GDPR) for digital twins and data spaces
Cybersecurity, resilience and safety-by-design for critical city services
Ethics, inclusion, accessibility and participatory approaches in digital twin deployments
Evaluation frameworks, KPIs and impact assessment for social good outcomes (energy, mobility, health, climate, equity)
Topics are indicative and non-exhaustive. Related work is also welcome.
