Thanks Scott. Part of the reason I gravitated to a magic property to do this instead of inference, which would have been my first preference, is because while I use SPIN inference a lot in Composer, I find that configuration and control of inferencing in Ensemble is unclear to me. For example, how do you cause a model to run inferences when it is opened, so that the triples inferred by spin rules on the opened model are available to the grid? Do I need to write an SMS to trigger inferencing as a result of a user action as an analog to "run inferences", or is this something that can be configured to happen automatically.
