In this example, everything is an 'information resource': both the Wiki and the article about it. How would this work for something (like for example Shakespeare, or for that matter my toaster oven) which is not 'on' the Web at all? How would Semantic MediaWiki make a URI denote one of those things? By the way, nobody has written any definitive Web articles about my toaster oven. >The "concept identifiers" or concept URIs are of this like: >http://ontoworld.org/wiki/Special:URIResolver/Semantic_MediaWiki So what this does, apparently, is to do a 303 redirect to a URI obtained by removing "/Special:URIResolver" from the concept URI. How does that make this concept identifier denote a thing? Where in all this is there anything to associate any URI with an actual object? In the earlier example, how can MediaWiki establish a connection between a URI and Shakespeare? It is not enough to say that the article itself identifies the object it is 'about': we have already established that that alone is not sufficient to determine the denotation. So what does determine it? >I don't know if they do the 303 thingy, but I think they do They seem to, as outlined above, at least in this example.
