Load item from truncated reference

This use case intends to load an entity by its reference received by peer. It is internally using the specific use cases of each entity:

• If the reference references a Token, fetches the Token just like the Load Token created by others use case. For example, if the content of the Token is a TokenContentDeviceSharedSecret, a DeviceOnboardingInfo is returned after successful execution of the use case. A TokenContentDeviceSharedSecret is created by the Create Device Onboarding Token use case.
• If the reference references a RelationshipTemplate, fetches the RelationshipTemplate just like the Load RelationshipTemplate created by others use case.
• If the reference references a File, fetches the File just like the Get or load File use case.
