Hello, I have a simple case where I have a single property (call it pth) that I want to traverse as a path to discover what the shortest path from 'A' to 'B' is. Finding that there is such a path is fairly simple: "where A (pth*) B"
But I can not figure out how to perform a query that will find the shortest. I did discover that P_Shortest is not implemented in the PathEvaluator (not sure why). Assuming there there are triples: a pth x a pth y x pth b y pth b TripleNode(a pth x) cost 5 TripleNode(x pth b) cost 5 TripleNode(a pth z) cost 5 TripleNode(z pth b) cost 4 Is there any way to query to find that a -> z -> b is the shortest path? Does anyone know if there are any SPARQL plans to support such a query? Thanks in advance, Claude -- LinkedIn: http://www.linkedin.com/in/claudewarren
