I am trying to write a SPARQL query to return a path from a source to a destination.
Below is the Turtle file representing the data set.
@prefix node: <http://prism.uvsq.fr/>.
@prefix edge: <http://prism.uvsq.fr#>.
node:a edge:p node:b.
node:a edge:q node:f.
node:a edge:p node:g.
node:b edge:p node:c.
node:c edge:q node:h.
node:c edge:p node:i.
node:c edge:p node:d.
node:d edge:p node:e.
node:f edge:p node:g.
node:f edge:q node:l.
node:f edge:p node:k.
node:g edge:p node:c.
node:g edge:p node:f.
node:h edge:p node:n.
node:i edge:q node:j.
node:j edge:p node:o.
node:j edge:q node:n.
node:k edge:p node:l.
node:l edge:p node:g.
node:m edge:q node:g.
node:n edge:p node:m.
The image next presents the same information, for easier visualization.
The query I wrote so far is the following:
prefix graph: <http://prism.uvsq.fr/>
prefix node: <http://prism.uvsq.fr/>
prefix edge: <http://prism.uvsq.fr#>
SELECT * FROM graph: WHERE {
node:a (edge:p|edge:q) ?des.
?des (edge:p|edge:q)* node:h.
}
The returned information only shows one level of the solution (it shows the possible neighbor nodes for reaching the destination).
Thanks in advance for your help.
Best Regards
