## Common Elements

The CommonElements model provides a central container for tags and classifiers. These elements are used in many sub models where references to Tags or Classifiers provide a mechanism to annotate objects.

### Tags

Tags are a generic possibility to annotate objects in the AMALTHEA model.

### Classifiers

Classifiers are used to define specific features or abilities of a core or a memory. They are used in the PropertyConstraintsModel to restrict the allocation to cores or the memory mapping.

### Namespaces

Some elements in the data model can refer to a Namespace. A namespace provides a prefix to the name of the element.
