Yes that's correct, it would be great if there was a possibility of resuing that as field editor instead of this:

[UIOMaticField(Description = "Select the owner of the dog", View = UIOMatic.Constants.FieldEditors.Dropdown,
   Config = "{'typeAlias': 'person', 'valueColumn': 'Id', 'sortColumn': 'FirstName', 'textTemplate' : '{{FirstName}} {{LastName}}'}")]
public int OwnerId { get; set; }

to be honest for the dropdown list is fine but for ListView is way more useful as it gives options like hiding create or delete button.
