National LDT Appstore

A trusted catalogue layer for Local Digital Twins

The National Member State LDT Appstore makes building blocks for Local Digital Twins discoverable, comparable and reusable. Think of datasets, data and geoservices, simulation models, workflows, dashboards and 3D visualisations.

What it is

Not a standalone software store, but a reliable catalogue

The Appstore is a standards-based overview with rich metadata, interoperability claims, quality information and trust signals. This enables governments, businesses and civil society organisations to compose, test, procure and scale solutions more quickly.

  • Datasets, data and geoservices
  • Simulation models and workflows
  • Dashboards and 3D visualisations
  • Metadata, quality and trust signals

Why it works

Reuse without starting from scratch every time

By making digital building blocks discoverable and comparable, the Appstore reduces duplication and accelerates development, collaboration and scaling.

  • Prevents duplicate work
  • Accelerates pilots and scaling
  • Supports public procurement and assessment
  • Makes solutions easier to compare

European connection

From local assets to European discoverability

The Appstore forms a national link towards Europe and connects with the EU Local Digital Twin Toolbox and federated discovery according to the “no wrong door” principle.

  • Discoverable locally, nationally and across Europe
  • Connection to the EU LDT Toolbox
  • Federated discovery
  • Consistent standards and metadata

The role of twinlink.eu

Governance first, then technology

twinlink.eu helps regional parties jointly manage one shared reality: with clear rules for fair data sharing, practical tools and cross-sector collaboration.

The goal is to safeguard trust, transparency and stakeholder interests at local, regional, national and European levels.

01

Fair rules for data use

Clear agreements on access, ownership, quality, responsibility and reuse of data.

02

Cross-sector collaboration

Support for joint decision-making between government, industry, knowledge institutions and civil society organisations.

03

Alignment with existing standards

Connection to frameworks such as DigiGO/DSGO, ILS-WoCo, DICO/ETIM, IFC, INSPIRE, Local Digital Twins, BAG/BGT/IMGeo and PRE-MADONA.

Once the rules are clear, the technology can be activated

This creates a shared digital foundation on which all links in the chain can collaborate using the same up-to-date and reliable information.

Regional SPoT

Shared Point of Truth

One harmonised source with agreed input, definitions, quality rules and reliable information for the region.

Common Workspace

Analyse and decide together

A shared environment for analysis, simulation, scenarios, dashboards, working agreements and chain collaboration.

From that moment on, all links in the chain can collaborate based on the same reliable information, with connected processes that accelerate implementation and enable reuse.
