 ====== InputData Objects
+The InputData object is the member responsible for indicating all mutable content available to the JobPack image at
+runtime.
+
+* The InputData object MUST have a member `name`. The member's value MUST be a string indicating the environment
+variable name that will be injected by the processing platform for job consumption.
+* The InputData object MUST have a member `type`. The member's value MUST be a string containing either `file` or `json`
+as the value. This value SHALL determine whether the value is directly injected or a reference to a file is given.
+* The InputData object MAY have a member `required`. The member's value MUST be a boolean indicating whether this input
+value MAY always be expected. If omitted, the default value MUST be treated as true.
+* The InputData object MUST have a member `content`. The member's value MUST be an object containing at minimum a member
+`mediaType` with a value of string elements for `type` of `file` or a member of `type` when `type` is `json`. These
+elements MUST be used by the processing system to validate file input.
