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
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
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.
