What is it you want to do again?  While there isn't a "memberOf" 
property with domain rdf:Resource [actually, rdfs:Resource] and range 
rdf:List, there *is* an official rdf:first property with domain rdf:List 
and range rdfs:Resource (and the range resource is the actual "member"). 
  Admittedly this is the other way around, but for query purposes (on 
well-formed RDF collections) it's not clear why the "change in 
direction" matters.
