My example was simply an example in a discussion *here*, which is why the URI didn't dereference to anything. You seem to deliberately ignore the scenario I'd set up that stated that the URI *did* dereference to an XML Conceptual Graph document. Why? I dunno -- perhaps to make a different point. My point was however that there was something at the other end of that URI, something that was useful in describing the concept I was conveying, or pointing to such a description. And if that was an XML Conceptual Graph document, an XTM document, whatever, that would provide precisely the methodology that you are requiring. The transmission of that URI was designed to allow for the transmission of either identity or information about an identity. Heck, all of the URLs on billboards in silicon valley are based on that proposition. No static necessary. Murray ...........................................................................
