A Hydra-based Rails Engine that extends an application, adding the ability to Create, Read, Update and Destroy (CRUD) objects (based on Hydra::Works) and providing a generator for defining object types with custom workflows, views, access controls, etc.
In digging through the code I see a usage of curation_concern.in_collection_ids; Which I believe is coming from the relationship :in_collection (and is clearly not a private method call).
This is a private method that is not referenced.
