RE: Re: URIs, concrete (was Re: Un-ask the questio
Hi Jonathan, Jonathan said: So if your namespace name resolved to a porn site, as in your example, I'd say that this is a _contradiction_. The user of the namespace, i.e. the user and/or creator of the XML document is asserting that the namespace URI identifies a namespace. The owner of the URI is asserting that the URI represents a porn site. I assert that namespace names and porn sites are disjoint, hence the contradiction.Contradictions don't give us a logical problem, they are just wrong. '3 = 2' is wrong that's all. Didier replies: If we set as an axiom that both the URI and the porn site are disjoint sets, they are. However, if some curious fellow enters the URI (in that special case a URL) in a browser and get to a porn site, from the human and cognitive point of view I just create confusion since the poor fellow will try to resolve the cognitive dissonance between these two disjoint sets. I wont say like Gregory Bateson that this would lead to some pathological state caused by a double bind but I would, at least, say that our fellow will be confused. I think that people will relate the URI and the vocabulary identified by the namespace reference. The URI, standalone, convey some information. If that latter is used for other purpose like, for instance, URLs used to retrieve information with a browser, well constituted human being will tend to resolve the relationship between the URI and what it represents. In my own opinion and common sense, the URI and what is represented by it are closely linked (from the psychological point of view and our natural tendency to find closure and meaning) I thought that one advantage of XML is that human can read it and make deduction about its purpose. I am not convinced that the actual usage of URI in the context of RDF and namespaces makes these documents more readable. We have to be very cautious with our choice of axioms.
