16/// Relation instances are edges from an outbound entity instance to an
17/// inbound entity instance.
18///
19/// The relation instance is of a relation type. The relation type defines
20/// the entity types of the outbound entity instance and the inbound entity
21/// instance. Furthermore, the relation type defines which properties
22/// (name, data type, socket type) a relation instance have to have.
23///
24/// In contrast to the relation type, the relation instance stores values/
25/// documents in its properties.
