#subject ⇒ Object

subject_decorator -> internal method -> subject subject_decorator -> lambda -> subject (base_uri + (id_method -> id)) -> subject There are several ways to create the subject. First, the subject_decorator will use whatever instance values that are set to build a pattern. Second, the base_uri and id are combined to create the subject.

Note, the id can be set directly, or set with the id_method, so UUID, or an external source, or a slug generating method can be used to generate an id.
