It is natural to want to make statements about resources and about representations of resources. It is necessary to distinguish between the two when targeting an assertion, since most assertions about resources are going to be statements about the range of representations over time. In other words, the reason that REST distinguishes the two is precisely because we wanted to solve that problem back in 1995. It is solved for HTTP/1.1. Now we just need to find the corresponding syntax for it in RDF. You mention: "We could remove the indirection if we could know for certain that HTTP URIs identify "documents", since we could be fairly sure that the URI above represents some online documentation about the tool, and not the tool itself." This reasoning assumes that people would not want to make statements about documents that describe other documents (not just other objects outside of Web-space), and therefore is less reliable than simply making the distinction explicit. In any case, the precondition is false, so let's move on to a solution that will actually work in practice. ....Roy
