 | comments | no | array of strings | One or more comment lines describing this chassis. |
 | number | yes | number | Chassis number within the system.  Chassis numbers start at 1 because chassis 0 represents the entire system. |
+| inventory_path | yes | string | Specify the relative D-Bus inventory path of the chassis.  Full inventory paths begin with the root "/xyz/openbmc_project/inventory".  Specify the relative path below the root, such as "system/chassis". |
 | devices | no | array of [devices](device.md) | One or more devices within the chassis.  The array should contain regulator devices and any related devices required to perform regulator operations. |
