It's consistent with Joshua Allen's comments last year that a 'resource is a hypertext dispenser'. I don't know if it is more revealing than that but it is certainly the common assumption right up there with a 'resource is a server'. Does it help the architecture document to know that or is it a qualification of a use of a URI in a context? >No, look. Interoperability does NOT require that we pick a single >fixed semantics. All it requires is that your semantics for the URI >and my semantics for it are *compatible*. Umm... the syntax for The URI is it's semantic. Past that, a different system and therefore different semantics are the basis of interoperation. How far 'compatibility' gets one is different system by system. Reliability differs by proof so in that sense, you are right. I don't know if that helps to get a web architecture document completed because so far, there isn't a definition for the Web that meets everyone's different notions of proof. The Web architecture document is supposed to be that definition, I hazard, but the process of creating that won't close without a definition for 'done' and without some assertion/proof boundaries, that won't happen. I suspect URIs are bigger than the web because they are used off the web too. A URI on a billboard is not a resource on a web. It is a syntactically correct URI on a billboard. One can say it is part of the web but that is silly on the face of it; it is far simpler and just as correct to say it is a non-web system using a URI for whatever it does, but the web architecture being a system architecture, doesn't care. len -----Original Message----- From: pat hayes [mailto:phayes@ihmc.us] Sent: Monday, July 21, 2003 1:32 PM To: Sandro Hawke Cc: Dan Connolly; www-tag@w3.org Subject: Re: [httpRange-14] empiricism was Re: resources and URIs > > http://www.w3.org/1999/XSL/Transform >> http://www.w3.org/2000/svg >> http://www.w3.org/2001/XMLSchema >> >> Now we have 3 URIs created by the W3C over the course of 3 years.
