wow, pradeep, that's exactly what i'm looking for. I'd be very interested in seeing your path-finding code/tool!
Looking forward to reading your paper today once I get some free time! thanks again! don btw - would you mind if I posted the link to this paper, on the NYC semantic web wiki? http://www.swnyc.org/index.php?title=RDF_Shortest_Paths_Analysis On Thu, Jan 29, 2009 at 5:34 PM, Pradeep <[email protected]> wrote: > > Hi, > I see what you are trying to find.
