The relationship between a "resource/thing" and a URI is not symmetric. One thing can have many URIs but a URI can only identify one "resource/thing". In the web, we only work with URI -> representations, but not the other way around, right? So, in your question, what is the exactly the "document" you have in mind? A file on a remote server? Or a cgi script? Or something else? My point is: the question that you posted, i.e, if a "document" can have multiple URIs, is an implementation issue. It is irrelevant to the Web architecture so you can freely infer anything. What is important is what is identified by a URI, i.e., given a URI, what you can get back. Xiaoshu
