Check for change in structure

Mar 21, 2013 at 1:58 PM
Recently twitter added a new field called "favorite_count". I missed it.

I want to know if there is any way I can store the structure of a json file, so if there is some change in the future I know it immediately via the program logs.

Like check if the structure is same or something is add/deleted. I have an object created which captures each value specifically and pushes it to the database.
