Hi James, - James said: But under my scheme, what following "hname" is in http URL scheme syntax with the assumption that you would use exactly the same thing after the colon as you would if the scheme was http. Eg hname://www.megginson.com/exp/id/airports/KLGA I agree that it isn't 100% guaranteed to be unique as someone else could come along and define the semantics of what follows "hname" as meaning that someone could legitimately use the above and not be owner of megginson.com but I think that is almost impossible. Didier says: And the advantage is that hname is not identified to a resource access protocol like http. when we use http, and because most of us using the web to access resource do use http protocol when we read a resource, http is associated already to a certain meaning. It implicitly carries the meaning of doing a "GET" this resource. "hname" has the advantage of not being tagged with such meaning, even if the rest of the url is the same. At least we do not say that we'll use the http protocol to "GET" a resource. Simple question of meaning and in this case, http carries some meaning. So, what James is doing is that he just tell the reader that this url is not a resource transport protocol but something else. This way, James do not do semantic overload on a single term. Otherwise I would call everything in my sight "car". Economical way to call everything (a single word) but I am not so sure I could be understood. So even if a urn is not necessarily used for name space reference, at least if it do not refer to a url with a different meaning. In fact, I think we should send this comments to W3C which by the way seems also to use http protocol like someone using a single word to call everything. I am surprised that nobody within WG made comments on this. the only rational thing I would see about this is that sooner or later the intention is that a document will be stored at the location referred by the http url. In this case, it makes a lot of sense, otherwise, its like the guy using a single word "car" to name everything. regards Didier PH Martin mailto:martind@n... http://www.netfolder.com xml-dev: A list for W3C XML Developers.
