Schema-register: idlink

Reusable object that contains an id to a resource and links where the object is described or a representation retrieved. Typically it is useful for paths like \resources and \resources\{resourceId}. \resources will respond an array of id-link listing the resourceId and the links to get it. \collections and \collections{collectionId} is an exception to this pattern. The fact that links is an array can be used to advertise the same object representation in different formats.
