Every triple has an ID. And every ID belongs to a graph.
Because I want to use non standard reification (because it would be to
heavy),
I would like to know the ID's of triples, to use them in URL's and
reuse the URL of a triple in another triple.
ARC2 either returns different types of information for SELECT vs
CONSTRUCT, but I don't think I can use either to get the ID of a
triple.
What would be the best way to use / extend ARC2 to get the ID or graph
of a triple?
Are there existing methods that I've missed? Or should I try to write
something myself?

So ... I just noticed SPARQL can be used to select the graph... (don't
know why I didn't think of that / check that before )
$res = $this->store->query('SELECT ?g WHERE { GRAPH ?g { <your>
<triple> <here> } }');
that's what I was looking for!
