I know fro the spec you are right since the TAG group and Roy cut it as the
result of an HTTP GET. However from the knowledge modeling and philosophical
point of view, seeing the (s) as a representation of (o) makes a lot of
sense.

If I want to model a resource, there are several approaches I can use to
model it. A phenomenological approach is one of them, a platonic approach is
another one, etc... Let say that the resource/phenomena reveals itself
through a certain representation accessible to my senses or my cognitive
processes then a triple seen as a representation make sense. It implies a
certain philosophical approach.

Now from the operational point of view I can add express everything I now
about a resource with triples and that includes all the representations I
can get with http verbs, the links contained in other representations about
this representation (we cannot say for sure that the links are about the
resource, the context may be that they are about the representation since
others like us can only know the tip of the iceberg about a resource - i.e.
only some representations). But for simplicity of the model let's say that
they provide some statement about a resource.

Concretely speaking I can use Google to provide me the links and encode the
result in RDF, the resource to provide me at least a representation and some
more statements from my own observations. As long as the statements do not
overlap the union of all these sets results into a larger property set
representing my view of the world about this resource. Interesting
experiment to try in my labs, just to see...

Cheers
Didier
