A PackageRelationship defines an association between a source Package or PackagePart to a target PackagePart or external resource. The source object is considered the "owner" of the relationship.

The PackageRelationship class has no public constructor; instead, two Create methods are used:

Package.CreateRelationship

Creates a "package-level" relationship—from a package to a specified part or external resource.

PackagePart.CreateRelationship

Creates a "part-level" relationship—from one part to another part or external resource.

The source package or part is identified by the SourceUri property of the relationship. The target part or external resource is identified by the TargetUri property of the relationship.

Creating or deleting a relationship does not affect the source or target objects in any way.

If a source object is deleted, all relationships owned by the object are also deleted.

Relationships enable navigation both in a document and between documents. Relationships also support document object model services, such as linking a PrintTicket to specific document elements when printing.

For more information about PackageRelationship elements see Section 1.3 "Relationships" in the Open Packaging Conventions specification available for download at http://go.microsoft.com/fwlink/?LinkID=71255.
