After all, it's all links in linked data. The property should carry the semantic value that expresses meaning of the relationship is between the subject and the object.

MADSRDF has "hasCloseExternalAuthority," which seems to be a good way of linking authority data, although in a very library-specific way. That may be more accurate than the over-used OWL:sameAs, which is "different names that refer to the same individual," but it won't be as widely understood.
The problem with hasCloseExternalAuthority (or hasExactExternalAuthority) is that as far as I can see these are intended to link an authority to an authority. Given agreement that BIBFRAME Authorities are not the same as LCSH or LCNAF authorities, then I'm not sure these are appropriate.
I think it comes back to your question in the "BIBFRAME Authority - Terminology" thread - what is the nature of a BIBFRAME Authority. This question bothers me as well, and is one of the reasons I proposed splitting out the concept of transcription in the "BIBFRAME Authority - Transcription" thread I started (no takers on that so far 'tho'!) - to try to distil the BIBFRAME Authority until we have the essence of what it is. I think until I have a better grasp of this I'm going to struggle with the semantics of how a BIBFRAME Authority links to 'Authority Files'
