This question is a little confusing to think about (at least for me), because "friend of" is, in real life, always a bi-directional relationship. So let me substitute something that's more clearly one-directional for this example: how about "has been to the house of".
Looking at it that way, I don't believe your first example will work. I don't think there's any way to determine whom a person "has been to the house of" - you can only find out who "has been to the house of" a certain person. I think what you're looking for is an inverse query, which isn't supported, though the issue has come up before on this mailing list. -Yaron On 5/17/07, Jim Wilson <[EMAIL PROTECTED]> wrote: > Hi SMW Devs, > > Quick question: is there a way to get a list of all articles that meet a > reflexive criteria? > > For example, I've got a relation called "friend of", and I know how to do > these types of queries: > > <ask>[[User:Whoever]][[friend of::*]]</ask> - This will return all articles > that User:Whoever is a "friend of" > > <ask>[[friend of::User:Whoever]]</ask> - This will return all articles that > are "friends of" User:Whoever > > Is there a way to get the intersection of these two sets?
