public class Entity extends Identifiable
Entities are uniquely identifiable objects, often also uniquely identifiable outside of this technical system - by additionally having unique identifiers of other systems (like GND-Id, VIAF-ID, etc.). An entity is of a specific entity type, like e.g. cultural object, item, manifestation, work, digital object, person, corporation.

Bibliographic entity types for example are defined in the “Functional Requirements for Bibliographic Records” (FRBR; deutsch ‚Funktionale Anforderungen an bibliographische Datensätze‘): see Wikipedia “Functional Requirements for Bibliographic Records”, URLs:
