Optoelectronic device simulations rely on mathematical models whose formulations and assumptions are often only partially documented in publications, making results difficult to compare and reproduce. We present MathModDB, an ontology-based database and knowledge graph for the systematic documentation, discovery, and reuse of mathematical models. Covering more than 200 models, including semiconductor and optoelectronic use cases, MathModDB supports model findability and citation. In this talk, we will illustrate the MathModDB ontology on drift-diffusion-type models and related extensions commonly used in optoelectronic device simulation.
