Access to relationships is supported at both the COM level and the Automation level. Given a versioned relationship that connects two repository object versions, you can perform the operations listed in the following table. These operations are performed relative to a specific version of the source object.
| To | Use |
|---|---|
| Pin the destination object version | The Pin method of the IVersionedRelationship interface. |
| Unpin the destination object version | The Unpin method of the IVersionedRelationship interface. |
| Retrieve (a version of) the target object | The Target property of the IRelationship interface. |
| Retrieve the source object version | The Source property of the IRelationship interface. |
| Create a new relationship to relate a new target object to a source object | The Add method of the IRelationshipCol or ITargetObjectCol interface. |
| Relate a subsequent target object version to a source object | The Add method for the TargetVersions collection. This collection is accessible through the IVersionedRelationship interface. |
