The complete OntoSim-Dis ontology, an ontology of disease simulation models. This file contains no term: it imports the nine modules and carries the metadata of the whole.

The modeller describes a model and the disease it represents; the reasoner infers whether the disease is coupled to the population, and whether the model realises that coupling.
