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.
