That second sentence is where this approach loses its appeal for me. IMO, it doesn't really suggest to go and check "collection X to find out if Markus knows more of them". Of course, you can always do, but why should you. A person, and that's all we know about that blank node, might be a member of multiple collections. Why should I go and inspect exactly this one to find Markus' friends? > I'm not saying there will be more in there. just saying that you could > check it. > Handy for a hypermedia client.

I would be interested to hear your opinion on the thought I posted yesterday: { "@id": "/markus", "hasRelationshipIndirection": { "property": "schema:knows", "resource": "/markus/friends" } } It could also be tweaked into something like { "@id": "/markus", "hasRelationshipIndirector": { "schema:knows": "/markus/friends" } } so that it works nicely with property paths. -- Markus Lanthaler @markuslanthaler
