[Virtuoso-users] Virtuoso inference capabilities

Hello, I have my RDF triples in a Virtuoso Open Source version 07.20.3217. When querying my data, I would like to have some inferences already done (so that I am querying inferred stuff). I have read some documentation regarding this matter, and I reach this one (http://docs.openlinksw.com/vir
