The abstract generalisation of any model element that can be referenced unambiguously. To enable this, the metaclass specifies a unique identifier whose value is required to be:
- independent of the semantics, structure or content of the model element;
- independently generated and protected from user or programmatic manipulation;
- immutable throughout the lifetime of the model element.
