Tim, Either the web architecture is URI scheme agnostic or it isn't. If the TAG is coming up with architecture that is scheme dependent then IMNSHO, its broken. And, dammit, URNs are dereferencable regardless of whether or not you keep bringing up conversations that are almost 10 years old. The rest of us moved one but you decided not to pay attention or keep up with the work. If you need to dereference one then you can look in your local catalog, in a proxy, or you can use the DDDS based URI Resolution application that is in the process of being deployed (using the same technology as ENUM which is being deployed in IP telephony networks as we speak). Over in the IETF we continually have to deal with the _destruction_ that middle boxes and transparent cashes are causing to the end-to-end model _specifically_ because the 'http:' schemes resolution processes are broken for a lot of applications that _need_ something like the DDDS resolution model. Can the TAG answer the question please: is the Web architecture really URI scheme agnostic or isn't it? Or is the web limited to the fixation some have with 'http:'? Are we really designing something that is generic and evolvable over time using a real architecture that allows more than one namespace? Tim, sorry to get bent out of shape but this FUD (and it is __FUD__) has been going on for 10 years and I'm frankly quiet tired of it. -MM > On Monday, July 1, 2002, at 04:48 PM, Dare Obasanjo wrote: > > Dare Obasanjo wrote: > >Since URIs comprise the set of URNs as well as URLs I'm not sure exactly > >how one can state that namespace names should be dereferencable if there > >is no uniform mechanism for dereferencing URNs nor is it clear whether > >they were originally designed to be dereferenced. > > > >-- > >PITHY WORDS OF WISDOM > >In the field of observation, chance favors only the prepared minds.. > > > >This posting is provided "AS IS" with no warranties, and confers no > >rights. > > -- -------------------------------------------------------------------------------- Michael Mealling | Vote Libertarian! | urn:pin:1 michael@neonym.net | | http://www.neonym.net
