Hello Hugh, I was reading the referenced page by Benjamin (http://docs.openlinksw.com/virtuoso/rdfsparqlrule.html). If subclass inference is supported, it means I could query SELECT ?subWHERE {?sub a :Animal . ?sub :hasWings ?obj} And then I would get any sub which is an Animal or any subclass (Bird, Dog, Cat, etc.) and which is related to obj through the predicate hasWings? Would it work if I try it with your demo EndPoint? I tried sometime a similar query and it only retrieved sub belonging to Animal class but to Bird, for instance. What am I missing? Best, LG

Hi Benjamin By "web interface" I presume you mean the SPARQL endpoint (ie http://<your-hostname>/sparql), as I would expect this to work pretty much the same as with isql, with the exception that the query is not prepended with the "sparql" keyword ? Please provide more details on what exactly is failing for you ...
