Yes one URI for the file, another URI for the data

Traditionally (at least in HTTP) these two can be quite similar using the
URL / URL#hash pattern

The reason for this is that HTTP is predicated on data having a container
(the document), much like writing has a delivery mechanism (paper)

The web wont fail too badly if you confuse the two together, but the extra
layer of indirection provides for a more freedom and a more decentralized
architecture.
