Materialize an Object Type to a Dataset if backed by a Restricted View?

I have an object backed by a restricted view. I want to materialize the Object Types into a dataset, that will be locked down.

I get the following error:
Cannot export as dataset; gps policy enforcement is required

Can I do this ? How can I do this ?

This error is likely thrown because your restricted view includes columns that are represented in the ontology as strings or arrays of strings. In order to materialize the object type as a dataset, those columns need to be represented in the ontology as Marking properties, where you can then specify either the maximum CBAC marking or the set of allowed mandatory markings.

We have updated the error string, in an upcoming release it will read:

Cannot export as dataset; gps policy is not compatible. Marking filters within the restricted view policy must be ontologized as marking properties, not string properties, so that a max CBAC classification or mandatory marking set can be configured.
