To be useful in the way that Larry wants it to be (e.g. for citation), DURI has to nail down *both* of these. The DURI names not the original resource, but a checkpoint of the original resource - a second resource whose representations are, and always will be, the representations that the original resource had at the given time. (using AWWW terminology here.) I was just saying that the representations at a given time is a potentially infinite set with arbitrarily varying content. Jonathan
