Who is twinlink.eu for?

twinlink.eu supports organizations that develop, connect, reuse and scale local digital twins within a European ecosystem.

Cities & regions

For local governments that use digital twins to make better decisions about space, climate, mobility, energy and liveability.

National coordinators

For ministries and programmes that want to align, scale and connect initiatives with national and European ecosystems.

Knowledge institutions

For research institutions and consortia that want to share methods, models, standards and expertise.

Solution providers

For organizations that want to contribute interoperable tools, data, models and services to open digital twin solutions.

Connecting local digital twins

twinlink.eu helps local initiatives connect with reusable building blocks, trusted knowledge and European standards.

From data to insight

From data to better decisions

Digital twins make it possible to bring data, maps and models together. This helps public organizations plan smarter, collaborate faster and respond better to complex societal challenges.

Stronger together

Connect people, knowledge and data across local, national and European initiatives.

Better outcomes

Support policy around climate, mobility, energy, housing and liveability.

Reusable building blocks

Avoid duplicate work by making tools, models and standards easier to find.

Scalable impact

Make local solutions easier to transfer to other cities, regions and programmes.

Why MIM8 matters:

It helps Local Digital Twins become reusable, comparable and scalable.

Featured

Open Local Digital Twin framework

MIM8 is the Minimal Interoperability Mechanism for Local Digital Twins. It provides a common way to structure digital twins so that data, models, services and interfaces can work together across cities and projects.

twinlink.eu is exploring an open LDT framework aligned with MIM8, so future projects can start from a reusable template instead of beginning from zero.
