However, when I do that, I get the following error:
Failed to invoke procedure `n10s.nsprefixes.add`: Caused by: n10s.utils.NamespacePrefixConflictException: Invalid prefix + namespace combination: http://schema.org/ is a standard namespace that has the associated standard prefix sch
It appears that Neosemantics is forcing the use of the "sch" prefix for schema.org.
Can I override this restriction somehow? Otherwise I would have to change all my ontologies to use "sch" instead of "schema".
