But we didn't > consider it that much; is there a good reason? What's happening when you move a document? Isn't the document still the same? If so isn't it describing the same target? Even without moving the document, the RDDL description for RDDL is located at http://www.openhealth.org/RDDL/ . Is it describing http://www.rddl.org/ or http://www.openhealth.org/RDDL/ ? I think that the whole system would be more robust and easy to use if the target was explicitely mentioned. >>I like RDDL a lot, but I am wondering if it's not misusing simple XLink >>here since after http://www.rddl.org/ has been redirected to >>http://www.openhealth.org/RDDL/ , my understanding is that when I read: >> >><rddl:resource xlink:type="simple" > > ... etc ... > >>this is describing a link between the rddl:resource element of the >>http://www.openhealth.org/RDDL/ XML document and the document >>http://www.rddl.org/natures rather than a link between >>http://www.rddl.org/ and http://www.rddl.org/natures. > > > No, if you go and read the introduction to the RDDL spec, it states > clearly that the links are from the descriptions of the related resouces > to the related resources being described.

It meets the requirement "what's behind a namespace URI?", but doesn't meet the common usage of resources discovery on the web: if I find a web page by any mean I like to be able to tell what this page is about. When I find a RDDL document, I need to be a human being to have a chance to tell what that's about, it's very frustrating for web crawlers like the one I intend to present at XML Europe 2002 :) !
