# Chapter 9: Example PMML-s

QsarDB file format is using Predictive Model Mark-up Language (PMML) for the mathematical definition of in silico predictive model.
Literally every model type that has PMML support is also supported by the QsarDB repository.
Good example models that have sufficient data published are hard to find.
The following list includes examples for realized PMMLs for various definitions of in silico predictive models.
