RDFa serializer?

Anyone started on a graph-to-RDFa serializer? I acknowledge that it 
might - depending on input - create an ugly splodge instead of a nice 
HTML page. But that could be a better basis for beautifying than 
starting from scratch, particularly for those new to RDFa. Or those who 
are sketchy on the current detail of the spec (eg. me :)

OK, well what I'm thinking of is: http://xmlns.com/foaf/spec/index.rdf

Can we take a quick(?) example...

  <rdf:Property rdf:about="http://xmlns.com/foaf/0.1/openid" 
vs:term_status="unstable" rdfs:label="openid" rdfs:comment="An OpenID
for an Agent.">
     <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#ObjectProperty"/>
     <rdfs:subPropertyOf 
rdf:resource="http://xmlns.com/foaf/0.1/isPrimaryTopicOf"/>
     <rdf:type 
rdf:resource="http://www.w3.org/2002/07/owl#InverseFunctionalProperty"/>
     <rdfs:domain rdf:resource="http://xmlns.com/foaf/0.1/Agent"/>
     <rdfs:range rdf:resource="http://xmlns.com/foaf/0.1/Document"/>
     <rdfs:isDefinedBy rdf:resource="http://xmlns.com/foaf/0.1/"/>
</rdf:Property>


How should this look "ideally" in RDFa, to make nice HTML? How close 
could an automatic serializer get to that?


thanks for any help,

Dan
