Let me apply this logic: 1. "If the effort is takent to define IP address URL equivalences (using a domain-name system), then it's *less* work to just *use* IP addresses and simply not have to muck about with mappings." Moral: The HTTP URL system is distinct from a resource's physical location on a hard drive. 2. "If the effort is taken to define HTML CSS or XSL equivalences, then it's *less* work to just *use* <xhtml:i> for italics and <xhtml:b> for bold and simply not have to muck about with mappings." Moral: The style of a document is distinct from its semantics. 3. "If the effort is taken to define a nation-wide ID system in the United States that matches SSN with date of birth, hair color, and physical address, that it's *less* work to just *use* date of birth, hair color, and physical address when filling out tax returns and simply not have to muck about with mappings." Moral: The identity of a person is distinct from his or characteristics. As #3 indicates, this is not just about having a unique URI, as date of birth, hair color, and physical address surely uniquely identifies 99.99% percent of the population. To my mind, saying "the blond person born in 1 January 1900 living at 1 Main Street" is different than saying, "the person with SSN 123-45-6789. What happens when that person moves? What happens when Main Street is torn down? I make the same distinction between "the language identified by the URI uri:lang:en_US" and "the language described by the resource at http://example.org/languages/en_us". Garret
