Thanks very much for confirming the use of <fedora-model:hasModel
rdf:resource="info:fedora/fedora-system:ContentModel-3.0"/> as convention.
Some of our cmodels do not assert it, so I will update them to do so.

Yes, they do work, at least as regards CMA binding for dissemination execution.

That's what I'm doing now, though since your confirmation that cmodel objects
should assert <fedora-model:hasModel
rdf:resource="info:fedora/fedora-system:ContentModel-3.0"/>, I'll update all
our cmodels to do so. I'm then inclined to use Adam's original query suggestion
as it seems more efficient:
select $cmodel
from <#ri>
where $cmodel <fedora-model:hasModel>
"info:fedora/fedora-system:ContentModel-3.0"
Thanks very much,
