Agent cannot parse json asset

[robot-ranger]

Unless Im doing it wrong, It looks like the agent is expecting xml for assets. I tried sending the following with a curl command:

{
	"TaskArchetype": {
		"assetId": "LoadCnc",
		"Priority": 2,
		"TaskType": "MATERIAL_LOAD",
		"Coordinator": {
			"collaboratorId": "cnc1",
			"CollaboratorType": "CNC"
		},
		"Collaborators": {
			"Collaborator": {
				"collaboratorId": "r1",
				"CollaboratorType": "ROBOT"
			}
		},
		"SubTaskRefs": [
			{
				"order": "1",
				"value": "OpenDoor"
			},
			{
				"order": "2",
				"value": "MoveIn"
			},
			{
				"order": "3",
				"value": "ReleasePart"
			},
			{
				"order": "4",
				"value": "CloseChuck"
			},
			{
				"order": "5",
				"value": "MoveOut"
			},
			{
				"order": "6",
				"value": "CloseDoor"
			}
		]
	}
}

curl -X POST "http://192.168.1.1:5000/asset/load-cnc-1?device=mxi_m001&type=TaskArchetype" -H "Content-Type: application/json" -d @load-cnc.json

but got:

<?xml version="1.0" encoding="UTF-8"?>
<MTConnectError xmlns:m="urn:mtconnect.org:MTConnectError:2.3"

	<Errors>
		<Error errorCode="INVALID_REQUEST">Could not parse Asset.</Error>
		<Error errorCode="INVALID_REQUEST">: Cannot parse asset</Error>
	</Errors>
</MTConnectError>

We had eliminated xml in favor of json response docs from the agent. Can we add json parser capability to cppagent's assets?

This will need to be added as a feature. We do not have a json entity parser at the moment. I can add one, but it will be a lot of work with a full test suite.

I can start working on it soon.
