XFN provides a richer set of *relationship* information, but FOAF provides
more than relationship information -- it also includes:
1. hCard-like contact information, but richer in in some ways,
having built-in support for a bunch of different instant
messaging types (as against hCard where these are hacked onto
the "URL" property), different types of URL, etc;
2. topics and interests;
3. group/club membership;
All of which are beyond the determined scope of XFN. Having that kind of
thing makes FOAF very useful for social-networking type sites.
In terms of relationships, FOAF *can* go beyond foaf:knows by taking
advantage of two things:
1. Implicit relationships. If two people have the same
foaf:workHomepage, then they are probably co-workers.
2. FOAF is RDF. You can mix and match RDF vocabularies.
