Ah, ok, thanks. This seems approx. in the httpRange-14 space, in that
when trying to access a resource, if the URI only corresponds to a
"mention" you'll get a 303 See Other redirect to a different URI which
will typically have a description of the (real-world) thing in
question. If it's a "use" the response will be a 200 Ok together with
the representation of interest.

Whether or not that is the case, I don't see why the use/mention
distinction can't appear in RDF directly, e.g. :

<uri> a :Use .
<uri> a :Mention .

(I think I've seen a vocab around somewhere that includes a class
