We're preparing to use edition-based redefinition in our databases so we need to convert our views to have the keyword EDITIONING in the CREATE VIEW statement. This means we need to go into the definition and update these manually (or write a transformation) in the physical model.
It would be better if there was a boolean attribute for Oracle views that set whether it is editioning or not and the DDL was updated as appropriate.
The editioning property should also be set when importing from a data dictionary - currently this informaiton is lost.
