PUT / POST Methods Require RequestBody

[brian-comply0]

All PUT and POST methods require a requestBody element defining the data to be sent from the client to the server.

• For all PUT and POST involving OSCAL content, include the content below. This includes the following endpoints:
• POST /{model-name}
• PUT /{model-name}/{identifier}

        "requestBody": {
          "required" : true,
          "content" : 
            {
              "application/json" : {
                "schema" : {
                  "$ref" : "#/components/schemas/OSCAL{ModelName}"
                }
              },
              "application/xml" : {
                "schema" : {
                  "$ref" : "#/components/schemas/OSCAL{ModelName}XML"
                }
              },
              "application/yaml" : {
                "schema" : {
                  "$ref" : "#/components/schemas/OSCAL{ModelName}"
                }
              }
            }
        },

• For all PUT /{model-name}/attachment/{resourceUUID}/resource insert:

      requestBody:
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/OSCALResource"   

• Define OSCALsnapshot schema
• For all PUT /{model-name}/snapshot/{identifier} and PUT /profile/{identifier}/resolved-snapshot/{identifier} insert:

      requestBody:
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/OSCALsnapshot"   

• The payload for POST /{model-name}/{id}/snapshot and PUT /{model-name}/{id}/snapshot/{id} is specified as follows:

{
    "snapshot" : {
    	"description" : "markup-multiline",
    	"labels": ["token"],
    	"types" : ["token"]
	}
}

• labels have a cardinality of 0 or more

• types have a cardinality of 0 or more

• description has a cardinality of 0 or 1

• The payload for POST /{model-name}/{id}/resolved-snapshot and PUT /{model-name}/{id}/resolved-snapshot/{id}` is specified as follows:

{
    "snapshot" : {
    	"description" : "markup-multiline",
    	"labels": ["token"],
    	"types" : ["token"]
	}
}
