Bill--
If I'm not mistaken, you'll find an RDF statement:
<fedora-model:hasModel
rdf:resource="info:fedora/fedora-system:ContentModel-3.0"/>
in every cModel object. Might that be a query that can do the job? Something
like:
select $cmodel
from <#ri>
where $cmodel <fedora-model:hasModel>
"info:fedora/fedora-system:ContentModel-3.0"
