or with some inference/rule language, such as OWL, RIF or SPIN ?

e.g.

   [
     a owl:Restriction ;
     owl:onProperty :hasBadge ;
     owl:hasValue   :badgeX
   ]
   rdfs:subClassOf
   [
     a owl:Restriction ;
     owl:onProperty foaf:knows ;
     owl:minCardinality 5
   ]

or

   CONSTRUCT { ?p :hasBadge :hasBadge }
   WHERE {
     ?p foaf:knows ?p1, ?p2, ?p3, ?p4, ?p5 .
     FILTER (?p1 != ?p2 && ?p2 != ?p3 && ...)
   }
