How does the batch creation of nodes work?

POIs are batch added in the following format (a JSON array of objects):

[ 
{ 
    "name": "name_of_node_1", 
    "coords": [lon, lat] 
}, 
{ 
    "name": "name_of_node_2", 
    "coords": [lon, lat] 
} 
]

Coordinates are of the format longitude/latitude in decimal degrees, multiplied by 1e6. So for example, 58.234234 is entered as 58234234.
