Objects can be selected by querying the datasave property using the selection criteria “ds”. All EntitySet and data relationship objects that are datasave (i.e., have had the datasave property set by the user) are selected. (Objects that have the datasave property have their data records automatically preserved when the object definition is changed using a ZOM service.) For example, in the following command, all datasave objects are selected for use by the ZOMLIST service:

ZOMList +p ds

In the next example, all objects that are not datasave objects are selected:

ZOMList +p ds!
