MathModDB: The Knowledge Graph for FAIR Storage of Mathematical Models used in Applied Sciences
Abstract
Talk about MathModDB knowledge graph on the MMS Days 2025 in Warnemünde. The MathModDB knowledge graph originates from the research work of the NFDI consortium MaRDI.

2 •R&D teams often rely on mathematical models and concepts •Models are often scattered across manifold publications and internal documents •Finding the right model for a new research project (including assumptions, scope, required quantities, and references) is timeconsuming •Leads to fragmented knowledge and missed opportunities •Improve discoverability of models (including versions, variants, and application domains) •Provide transparency and thorough documentation of necessary formulations and assumptions •Connect and link research questions and domains to specific models •Enable easy search, maximum synergies and unique identification →Making mathematical models FAIR! Motivation: Create central repository for mathematical models Challenges Goals

The structure of MathModDB
16 The MathModDB/MaRDMO ecosystem brings the ontology to life! MaRDMO Plugin
17 MaRDMO: Future gateway to FAIR mathematical data MaRDMO Plugin •Connector tool for mathematical research data →See talk by Marco Reidelbach on Friday morning
18 OWL was and is used for ontology development Screenshot from Protege •Good for development •Not useful for practical purposes
19 Ontology is documented and published https://mardi4nfdi.github.io/MathModDB/https://github.com/MaRDI4NFDI/MathModDB
20 Implementation on graphserver in Münster •Operated by TA2 for MathAlgoDB •Intuitive graphical surface •Connection between algorithms and mathematical models
