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:

- Method Detail
  - getEntityType
```
EntityType getEntityType()
```
    Returns:
    
    the type of the entity (one of the types this system can manage, defined in enum EntityType).
  - setEntityType
```
void setEntityType(EntityType entityType)
```
    Parameters:
    
    entityType - the type of the entity
  - getRefId
```
long getRefId()
```
    Get the system wide unique reference id. Makes it possible to create very short permanent URIs by using a number.
    
    Returns:
    
    system wide unique entity reference id
  - setRefId
```
void setRefId(long refId)
```
    Parameters:
    
    refId - system wide unique entity reference id.
