The Project_Issues_Issue_Project association relates a project to the issues that it contains and relates a collection of issues to its project.

<Association Name="Project_Issues_Issue_Project">
  <End Type="ReportingData.Issue" Role="Issue_Project" Multiplicity="*" />
  <End Type="ReportingData.Project" Role="Project_Issues" Multiplicity="0..1" />






Identifies the entity types and the navigation properties that form the two-way association for projects and issues. In the first half of the name, Project is the entity type and Issues is the navigation property. In the second half of the name, Issue is the entity type and Project is the navigation property.



Schema element: ReportingData

The schema for the reporting data in the ProjectData service.

The Project_Issues_Issue_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.

Attributes of the End elements for the Project_Issues association






EntityType element: Project


There is one project entity that corresponds to a collection of issues.


EntityType element: Issue


There can be many issue entities that correspond with a project.

One end of the association is the Project entity, and the other end is the Issue entity. The Project entity type contains the Issues navigation property, where the FromRole defines Project_Issues as the start of the association to get the collection of issues in a project. Similarly, the Issue entity type contains the Project navigation property, where the FromRole defines Issue_Project as the start of the association to get the project that is associated with a collection of issues.
