Re: Find out in data if resources are connected

[Mikael Pesonen]

Sorry meant of course to find connections between known nodes, here x and y:

ASK {
      <x> ((<>|!<>)|^(<>|!<>))* <y>
  }

Hi,

is there a more efficient way to find out if two entities are connected? This

ASK {
      ?s ((<>|!<>)|^(<>|!<>))* ?o
  }

works for short, couple of relations long, paths but becomes too slow quickly. Maybe something like the list:member method for RDF lists?
