Child elements
The Project_Deliverables_Deliverable_Project 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 Project entity, and the other end is the Deliverable entity. The Project entity type contains the Deliverables navigation property, where the FromRole defines Project_Deliverables as the start of the association to get the collection of deliverables that are associated with a project. Similarly, the Deliverable entity type contains the Project navigation property, where the FromRole defines Deliverable_Project as the start of the association to get the project that is associated with a collection of deliverables.
