The OLS and the OWB/ETL capabilities are totaly independant of each other. That said, OLS generally creates a predicate that uses a simple column lookup and OWB can be used to fill that column.

The magic behind OLS is that the policies do not have to be written - that's discussed in the documentation I mentioned as well as the papers Pete Finnigan mentioned.

So first step will be to enable OLS (see the docco), followed by using OWB to transform and data fill to meet the policies.
