Well the R in URI doesn't stand for "resource" in general, but
"resource" as defined in the RFC which says:


Abstract

   A Uniform Resource Identifier (URI) is a compact string of characters
   for identifying an abstract or physical resource. 

....


      Resource
         A resource can be anything that has identity.  Familiar
         examples include an electronic document, an image, a service
         (e.g., "today's weather report for Los Angeles"), and a
         collection of other resources.  Not all resources are network
         "retrievable"; e.g., human beings, corporations, and bound
         books in a library can also be considered resources.
