Indesign Applescript Placed Object Layer Visibilty Override

Hi, trying to programmatically control layer visibility of placed objects (either AI or other ID files) in a multi-page Indesign document.  Have looked all over the dictionary but can't seem to figure a way to reference the layers.

Would someone have an example of how to do this in Applescript?  (Please, not javascript, will convert one day but for now am staying with AS.)

Thanks!
