Jeremy, I don't see that as an error of the M&S. To do what are you suggesting is to list all possible equivalent quantities (or as a many as you see fit). Normally, since here is only one or two that's fine. But why bother? Would we do the same for .../metres/centis/millis/...? Sure they have a family resemblance, but you still need an algorithm to convert between them. There isn't really any difference between 2 machines moving between pounds and kilos versus moving between kilos and tonnes. You just replace one algorithm for another. It doesn't seem incorrect to give only one measurement of John Smith's weight. If your machine doesn't know a particular unit of measurement, it can try to bind it to another and convert the amount. Or it can ask the source for any measurement mappings it might have. Or it can fail gracefully. Or some clever spark can try and siumlate the "Strategy" OO pattern in RDF whereby an RDF machine can give an input to another machine, telling it to convert to a given measure and return something it can manipulate.
