Subject: Clarrification of implications of <hasInstance>
Within a subject scheme map, hasInstance says that there is an instance-of relationship between container and contained subjects, e.g.: <hasInstance> <subject keys="person"> <subject keys="three-initial-corp"/> </subject> </hasInstance> However, what is the implication if the contained subject has itself subjects, e.g.: <hasInstance> <subject keys="person"> <subject keys="three-initial-corp"> <subject keys="some-subject"/> </subject> </subject> </hasInstance> Ignoring that this is probably nonsensical ontologically, what is the implication in this case: 1. This is nonsense and the meaning for "some-subject" is undefined. 2. "some-subject" is also an instance of "person" 3. "some-subject" is an instance of the subject "three-initial-corp" Based on analogy to <hasKind>, which is transitive, I might expect interpretation (3) but logic suggests either (1) or (2). The current subject scheme docs don't seem to say. Should we clarify?
