[foaf-dev] SPARQL Querying CCO

Hi,

I'm looking at the "Cognitive Patterns Example" on the page:
http://schemapedia.com/schemas/cco

Scenario: I want to SPARQL query this small dataset to obtain all
CCO:habits that have a wo:weight_value of 0.7 or more.

The result set would return:
cco:topic <http://dbpedia.org/resource/Category:Knowledge_representation>
cco:topic <http://dbpedia.org/resource/Category:Ontology_(information_science)>
cco:topic <http://dbpedia.org/resource/Named_graph>

And would omit:
cco:topic <http://dbpedia.org/resource/Category:Ontology>

Is there a SPARQL query that'd make this happen? I'm unsure how to
SPARQL query reified RDF statements.
