Re: [Virtuoso-users] Get all paths between two URIs with transitivity.

give this one a go :) SELECT ?x ?predicate ?y ?via ?dist ?path WHERE { { SELECT * WHERE { ?x rdf:type . ?x ?predicate ?y . filter( isURI(?y) ) . ?y rdf:type } } OPTION ( TRANSITIVE, T_DISTINCT, T_NO_CYCLES, t_in(?x), t_out(?y), t_mi

Re: [Virtuoso-users] Get all paths between two URIs with transitivity.

sorry; seem to have lost some of that email somehow :s correction: then changed the transitivity options to T_DISTINCT, and removed T_DIRECTION , removing it lets the optimizer pick what's best. also here are some docs: inference rules and reasoning in virtuoso: http://docs.openlinksw.com/virtuo

Re: [Virtuoso-users] Get all paths between two URIs with transitivity.

Thanks for that example. It looks to be very useful. I did a similar test on one of the Bio2RDF databases ( http://obo.bio2rdf.org/sparql ) and I am just wondering what it means to have the predicate is unbound in one of the result sets, as I don't necessarily just want to find paths using a pa

Re: [Virtuoso-users] Get all paths between two URIs with transitivity.

How do I find arbitrary paths out from one URI to all other URI's it is linked to without specifying the predicate? I can make the following query work, but if I don't specify the predicate the query fails The following works, which is very nice, but I would like to have both the predicate and
