And I'd add a graph, [1] at [2]: this is the kind of thing that is more difficult to do without RDF.
As a matter of fact the only two linked-data SKOS examples I know of, [3] and [4], are already connected (ok, partially, but that shows the direction to go!).

And further RDF is not about reasoning. That's more RDFS and OWL. And even then, reasoning based on incomplete semantic specification can still prove useful...
