DEMOS: DEMocratizing MOdelS ¶

A cross-discipline platform for sharing research models

DEMOS is a BMBF-funded research consortium (2025-2028) developing a federated and interoperable standard for sharing probabilistic models across ErUM (Exploration of the Universe and Matter) research fields.

What is DEMOS? ¶

DEMOS creates a common standard and infrastructure for serializing, sharing, and using research models across multiple physics domains. Our goal is to make models FAIR: Findable, Accessible, Interoperable, and Reusable.

Research Domains ¶

DEMOS serves researchers across six ErUM fields:

  • Particle Physics (PP)
  • Hadron Physics (HP)
  • Nuclear Physics (NP)
  • Neutrino Physics (NuP)
  • Astroparticle Physics (AP)
  • Laser Physics (LP)

Our Approach ¶

DEMOS is built on three foundational pillars:

1. Model Format Standardization ¶

Developing a common standard with flexible building blocks that enable models of varying complexity to be serialized, shared, and adapted across domains.

2. Portal & Infrastructure ¶

Creating a platform to facilitate model discovery and sharing, with computational engines in C++, Python, and Julia.

3. Community Engagement ¶

Working with the ErUM research community to establish and promote the DEMOS standard through documentation, showcases, and collaboration.

Consortium ¶

The consortium is led by Prof. Dr. Mikhail Mikhasenko (Ruhr University Bochum) and includes 9 research institutions across Germany and the US.
