What was the rationale behind having both void:target and the
combination of void:subjectsTarget and void:objectsTarget?

I would have thought that linksets would always be directed, otherwise
it leaves you uncertain about whether you can actually find anything
in one set or the triples are actually contained in the other dataset.
At least with subjectsTarget you can always be sure that that dataset
will contain the relevant triples. If people use two void:target
statements as part of a linkset can we only assume that they are
trying to include triples from both datasets at once? If so, the
target's might contain anything resembling the statistics that one
might be able to apply to directed linksets where one is really only
trying to describe a subset of triples from void:subjectsTarget that
happen to have object resources in another known dataset?

Cheers,

Peter
