From the description of this item on ArcGIS Online:
"This is a diagram generated automatically by a Python script ..."
The link in your 11/19/2013 post regarding an object model diagram no longer works and the attachment to the 6/10/14 post says 10.2.1 on the bottom. (AND IS EXTREMELY SMALL PRINT!!!) I really need the 10.1 version if you still have it. Thanks
The 10.1 version still exists. You can download it from here:

See attached for 10.0 version.
