| Temporality is a feature providing | |
| automatic versioning of model instances. The basic idea is to provide a Temporal | |
| mix-in base class that can be pulled into existing models. By simply | |
| extending the Temporal mix-in base class existing modeled types are | |
| supplied with temporal features. i.e.: they will keep track of changes | |
| made to the value of their attributes and references. | |
