ERElement (Information System Model 7.1.0-SNAPSHOT API)

All Superinterfaces:

Element, IdentifiableElement, ModelElement, Serializable

All Known Subinterfaces:

ConsistsOf<S,T>, Entity, Facet, IsRelatedTo<S,T>, Relation<S,T>, Resource

All Known Implementing Classes:

ConsistsOfImpl, DummyFacet, DummyIsRelatedTo, DummyResource, EntityImpl, FacetImpl, IsRelatedToImpl, RelationImpl, ResourceImpl
```
public interface ERElement
extends IdentifiableElement, ModelElement
```
An interface for identifiable entity-relationship (ER) elements of the model.
This serves as a common type for core model elements like Resource, Facet, IsRelatedTo, and ConsistsOf. It extends IdentifiableElement and ModelElement, and adds a property to retrieve the contexts in which the element exists.
