> According to http://www.hydra-cg.com/spec/latest/triple-pattern-fragments/ the object of the property void:triples is
> an integer literal expressing the estimated total number of matching triples"
> But http://www.w3.org/TR/void/ states:
> The total number of triples contained in the dataset
> And that document states for void:documents:
> This property is intended for datasets where the total number of triples or entities is hard to determine. void:triples or void:entities should be preferred where practical.
> That seems to substantiate that void:triples was intended for precise numbers, not estimates.
> In October 2014 there was a mail thread where a different opinion was presented:
> totalItems vs void:triples
> [mail thread]

> I think it would be better to define and use a new property hydra:estimatedTiples or hydra:triplesEstimate. Maybe that property can be defined as a super-property of void:triples.
