[Mulgara-general] "Could not commit creation of model ..."

[David Smith]

Use:  http://mulgara.org/mulgara#TypeGraph

I found it by looking at the built in models with this query:

select $subject $predicate $object from <rmi://localhost/server1#> where
$subject $predicate $object;

As you can see, there is also a "built in" type model named: "sys:type"

This was probably introduced in 2.0.6 with the change from the work
"Model" to "Graph" --- SPARQLism
