Child elements
The Assignment_Task_Task_Assignment association element contains two End elements that represent opposite ends of the association. The Role attribute is a lookup key that enables a navigational property to specify the direction in the association. The Multiplicity attribute refers to the entity type. Multiplicity indicates the number of entities that can be related at each end of the association: zero or one (0..1), or many (*). The Microsoft .NET implementation of OData uses 0..1 when the navigational property points to a single entity, rather than to an entity set.

Remarks
One end of the association is the Assignment entity, and the other end is the Task entity. The Assignment entity type contains the Task navigation property, where the FromRole defines Assignment_Task as the start of the association to get the collection of tasks that are associated with an assignment. Similarly, the Task entity type contains the Assignment navigation property, where the FromRole defines Task_Assignment as the start of the association to get the collection of assignments that is associated with a task.
