Of course it's not unique. Two different long-paths may lead to the same shortcut. E.g. consider two people making independent measurements, and coming up with the same result; or making independent statements that happen to agree about the value. This is in fact present in ULAN: there's a table BIOGRAPHY that has birth/death place/date, and Contributor (i.e. who said it). That corresponds to several E13 Attribute Assignments, which may well be over the same triple. > > - *all* properties are shortcuts of E13 Attribute Assignment. > > ** Does that mean we should infer an unknown E13 for *every* statement? > > ** How about E13's own properties P140 and P141: should we reify those > > with E13, ad infinitum? You have classified shortcuts into "soft" and "strict". Can you please explain the underpinnings of that classification? I really hope the E13 Attribute Assignment long-path is considered "soft" and doesn't lead to expansion ad-infinitum.
