[ . . . ] I think it is true for a 303, because by redirecing you somewhere else, the 303 is acknowledging that there is a resource associated with the URI. In the t-d-b.org case above, the URI owner is t-d-b.org, but because http://edavies.me.uk/1907/wibble does not return any content, the URI owner has not told you what resource it is that http://t-d-b.org?http://edavies.me.uk/1907/wibble denotes. However, I guess there isn't much difference in practice between a URI that has not been associated with a resource (i.e., minted) and a URI that denotes a completely unknown resource, so one could look at it either way. And BTW, the 303 response by itself does not constitute the complete "URI declaration"[3] that I mentioned. Rather it is one component (the speech act) in the URI declaration. In the example you gave above, there would not have been a complete declaration of http://t-d-b.org?http://edavies.me.uk/1907/wibble , because http://edavies.me.uk/1907/wibble does not return any content. > [1] http://thing-described-by.org/ > [3] URI declarations: http://dbooth.org/2007/uri-decl/ David Booth, Ph.D. HP Software +1 617 629 8881 office | dbooth@hp.com http://www.hp.com/go/software Opinions expressed herein are those of the author and do not represent the official views of HP unless explicitly stated otherwise.
