/ Pat Hayes <phayes@ihmc.us> was heard to say: | I wonder if the discussion taking place on public-semweb-lifesci might | be relevant to this? The message which gets you the thread | | http://lists.w3.org/Archives/Public/public-semweb-lifesci/2007Aug/0134.html | | was next to yours in my emailbox. Yes, that looks like the same issue to me. I have two immediate responses to the issue, which I will try to find time to articulate more clearly in the near future. But anyway, they are: 1. http: != dereference That is, there's nothing about using an http: scheme URI that mandates dereference. It's perfectly reasonable to use http: URIs for resources that need not be dereferenced to be useful. XML namespaces come immediately to mind. 2. The dereference problem is scheme independent Suppose that you avoid http: because you're worried about the cost of dereference. Instead you use a (insert your favorite other scheme here) URI. But, in fact, you *do* need to dereference it, so you deploy an architecture that allows you to do so. Now, you've got exactly the same problem, it just took you an extra indirection (and a whole bunch of new infrastructure) to get here. Be seeing you, norm -- Norman Walsh <ndw@nwalsh.com> | What is familiar is what we are used http://nwalsh.com/ | to; and what we are used to is most | difficult to 'Know'--that is, to see as | a problem; that is, to see as strange, | as distant, as 'outside us'.-- Nietzsche
