The vda5050_msgs package contains the datatypes (json objects) specified by the VDA "Arbeitskreis Schlüsseltechnologien" in their recommondation "VDA 5050 - Schnittstelle zur Kommunikation zwischen Fahrerlosen Transportfahrzeugen (FTF) und einer Leitsteuerung. This package provides the message files which can be used to be (de-)serialized with an implementation of mqtt (e.g mqtt_bridge) or to plain json (rospy_message_converter) or similar.
In NodeState.msg, the NodePosition member should have name of node_position; it was just position. This matches both with the v2 NodePosition spec and the Node.msg definition.
