Paul is entirely correct.

A URI is simply a name for a thing, whatever that thing may be. A name is
not the thing that it names, just as the string "Alaric Snell" is not you.
The concept of names was not invented yesterday, nor in 1991. The
relationship between names and the things they name has been formally worked
out in various logics etc. for centuries.

Since names are used to refer to the thing named, in common language the two
are often used interchangably. For example I might say, indeed above,
"Alaric Snell wrote:" or similarly "alaric@a... wrote:" and so
the URI is used as a rather mundane name to _refer_ to you, regardless of
whether you are connected to the Internet or not.

URIs are names. The point being made is that what they name is NOT the
literal series of characters returned by a GET, rather the URI names a
_resource_ which might be anything thing that has a name. What is returned
by a GET is simply a description of the actual resource (other wording is a
'representation of the resource').

URIs are names.
