> Sometimes we want to allow relationship to items from different collections. This would be tricky to implement in a situation where the collections could be defined, but may be feasible if we're talking about a relationship to the "repository level". This way we can map the features necessary from the collection to 'default', allowing, for example, the "displayed metadata" to be the core and repository-level ones.

> Allow the Relationship metadata to define it's collection\_id field as 'default' in order to create relationships to any item from the repository.
