Yes.  The way I see it, the "permanent object"/"moral entity" would be
whatever you describe in the text.  So if you put in the text "the Texas
School Book Depository", the uuid should move when the book depository
moves.  If you put in the text "the building where Oswald shot Kennedy", the
uuid shouldn't move when the book depository moves.  I'd think in most cases
you'd choose the former rather than the latter, but in some cases you might
really want to link to the latter (such as the example given).
