```
public class VarModel
extends ModelManagement<Project>
```
The variability model, the central class holding all project instances and being responsible for import resolution. Model loading is done by plugins of type IModelLoader. Public access shall be synchronized (in any way) as multiple source parts and tools may access the information concurrently. Please note that specific information and settings are available via ModelManagement.availableModels(), comments(), ModelManagement.events(), ModelManagement.loaders(), ModelManagement.locale() and ModelManagement.locations(). The variability model needs a loader and a location to operate. After providing this information, available IVML projects can be accessed via ModelManagement.availableModels().
