This is the Game Definition File Schema. It requires the Game Explorer Base Types schema to validate. The parental controls ratings are split into a "Rating ID" which is the actual rating, and a "Rating System ID" for the various rating systems. Each "Rating" has a set of Descriptors which represent specific content present in the game. You can either point the version number to a binary executable, which we will investigate for version information, or you can hard-code the version number into your GDF.
