Access to relationships is supported at both the COM level and the Automation level. Given a relationship that connects two Repository objects, you can perform the operations listed below. 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 |
