Indeed.

Ok, so would I be right with this:

<docAboutSomeDogs> foaf:topic <#Basil>
<docAboutSomeDogs> dct:subject <dogs/B/Basil>
<docAboutSomeDogs> foaf:topic <#Sasha>
<docAboutSomeDogs> dct:subject <dogs/S/Sasha>
...

where

#Basil is his WebID
and
<dogs/B/Basil> a skos:Concept

(and will 303 to a doc about Basil)

but what would x here be?

<dogs/B/Basil> x <#Basil>

(couldn't see anything obvious with a quick re-skim of SKOS, which
surprised me a bit)

Cheers,
Danny.
