I take this definition of resource as reflecting a fairly sophisticated understanding of the reality of identifying and naming objects. A single URN identifying an abstract work may identify a variety of physical manifestations of the work. The physical manifestations retrieved may vary radically based on the social/technical context of the person resolving a URN. Two different URNs may refer to the same abstract work, and retrieve the same or different physical manifestations depending on the work identified, context of the resolver, etc. When you have two URNs identifying an abstract concept, I don't see how you can reliably determine computationally that they both identify the same thing. Nonetheless, we need the ability to identify abstract works. The definition of URIs, encompassing both URNs and URLs, had to deal with this need. Jerome McDonough -- jmcdonou@l... | (......)
