Awesome!
@prefix dc: <http://purl.org/dc/terms/>.
<> dc:author [].
<> <> <> .
[] <> [] .
This is where I like RDF :)
I know now where to start a lesson on SemWeb :)

And since <> is general, we can take it as referring not just to identity but to space-time location, yielding <> = sum-here-now. Then if we discard the notion that RDF triples must be translatable directly or naturally to Subject-Verb-Object constructions in some natural language, we can write
