Thanks for this response. Just wanting to enquire how that is going. I notice
some changes to the Unbound Schemas list, but I have had no luck using or
expanding those new ontologies listed to get to the properties/classes under
each ontology/schema. The same or similar permissions error message is
generated.
William.

To cut a long story short, we can import the above as standard.
That should happen in the next day or so.
