National LDT App Store - what it is and why it works

The National (Member State) LDT App Store is a trusted catalogue that supports the development and reuse of Local Digital Twins by making key building blocks easily findable and comparable.

What she offers:

• Datasets, data and geo-services
• Simulation models and workflows
• Dashboards and 3D visualisations

Why it works:

• Not a software app store, but a standards-based catalogue
• Rich metadata, interoperability information and quality indicators
• Reduces duplication and accelerates development and scale-up
• Supports federated findability at local, national and European level
• Aligns with EU Local Digital Twin Toolbox (“no wrong door” principle)

The role of twinlink.eu: governance first, technology second

twinlink.eu enables regions and stakeholders to work together around a shared digital reality by putting trust, governance and fairness first.

twinlink.eu supports:

• Fair and transparent data-sharing rules
• Collaboration between policy, industry, academia and civil society
• Alignment with existing standards and European frameworks

Once governance is in place, technology enables the following:

• Shared Point of Truth (SPoT): harmonised data with agreed definitions and quality rules
• Common Workspace: analysis, simulation, decision-making and cooperation

This approach ensures that all stakeholders work with the same reliable information, speeds up implementation and enables reuse within regions and across Europe.
