In MIME and HTTP terminology, a URI (uniform resource identifier)
identifies a resource, and a URL gives a Location.

What is returned from dereferencing a URL using HTTP is a
representation of a resource.

This does beg the question, what is a resource. And what is
information. And then, what is an information resource?

But the series of octets is a representation in much the same way that
a physical copy of a book sitting in your hands is a “manifestation of
a work”—you are not holding Shakespeare’s sonnet, “Ode to a validator”
but a printed representation of that sonnet, possibly one of many. The
large print edition, the audiobook, the stone carving in the garden of
the Scottish sculptor, are each a different representation, and in book
terms another copy of the same edition and impression of the book you
hold is another manifestation.

For my own part i think that information isn’t intrinsic to a resource,
nor to a representation, but is something gleaned by inspection and
analysis. Communication happens when sender and recipient glean
recognizeably similar information.

<me> Bot, what is the name of the umpire?
<bot> Fact recorded: the name of the umpire is “what”.

(who’s on first base anyway?)
