is there any way to get an array of strings, where each string is a key name, of all the attributes and relationships of an entity in a model? this would be extremely useful when updating a data file to a new version, especially for updating entities that haven't changed in the new model. one could them simply itereate over all keys, getting the old value and setting the new value.
