This bsse class is to represent the entity base.

```csharp
public abstract class EntityBase : ContainerObject<EntityEventCore>, IObservableObject, IDisposableObject, ILinkable, ILinkContainerEvent, IVerifiable, IHistoryObjectSerializable, IAttributeContainer, IContainer, IEntity, IEntityBase, IObjectBase, IObject, ILinkContainer, IOwned, IHasID, IEventProvider, IHasKeyObject, IHasName, IEnabled, IHasComment, IVisible, IDocumentOwner, INamed, INavigatorItem, IVisible, IMultiChangable, IHasProperty

```
