I was the author of Appendix J and I tied my mind in knots trying to keep the reciprocals straight and the definitions pointed in the right directions. Clearly I wasn't uniformly successful!
In addition, I need to apologize for all the copy-and-paste errors. Those should have been fixed before the text went to the developers. This appendix is hard enough to keep straight, without having to deal with outright errors. I'm sorry about that.
I don't have the time or energy to sort all this out, so I'm simply including Kevin's comments, with a note to the JSC that further editorial work is needed.
One specific point: Some reciprocal relationships were omitted because the related entity cannot logically exist. For example, there is no relationship for "musical arrangement (work)" because an arrangement is by definition an expression and therefore a related musical arrangement must be a related expression -- covered by "musical arrangement (expression)". I hope that makes sense, although at this hour, I wouldn't know!
