Tools for 20 million triples?

Hi folks,

on another list someone asked what tools would be good for handling an
OWL ontology of about 25,000 terms, with around 20 million triples. There
were a
handful of ideas about how to build specialised SQL systems or similar, but
Danny Ayers pointed out that there are systems capable of handling RDF and a
lot of triples (which by lucky chance happens to be a way of storing OWL).

So I wondered if anyone on this list had experience of tools working with
this size dataset. (I will read Dave Beckett's report done for SWAD-Europe on
the topic, but I suspect that there is already new information available, and
would like to be up to date).

Cheers

Chaals
