Facebook Graph API: Getting latitude/longitude of a Checkin via Fields API (optimized calling) - facebook

Question

I'd like to know whether there is a way to directly get the latitude/longitude fields via the Facebook Graph API.
The background is that I want to reduce the amount of data which is returned by the Graph API by getting rid of fields which are not of interest for my application.
I know there's something like this working in the Graph API Explorer:
me/?fields=id,checkins.fields(id,place.fields(id,location),created_time)
It returns the following:
{
"id": "12345",
"checkins": {
"data": [
{
"id": "101511234546244",
"place": {
"id": "170048419682121",
"location": {
"street": "",
"city": "Frankfurt",
"state": "",
"country": "Germany",
"zip": "",
"latitude": 50.108641831527,
"longitude": 8.6654729704433
}
},
"created_time": "2012-11-08T08:30:48+0000"
}
]
}
As I don't need the address parts of the location, I'd really like to get rid of them as well. If I try this the follwoing way, it doesn't work:
me?fields=id,checkins.fields(id,place.fields(id,location.fields(latitude,longitude)),created_time)
The result is
{
"id": "12345",
"checkins": {
"data": [
{
"id": "101511234546244",
"place": null,
"created_time": "2012-11-08T08:30:48+0000"
}
]
}
Did somebody have success in doing something similar? If so, I'd be great if you could let me know. Thanks!

According to the API documentation and the Graph API explorer, Subfields are not supported by location so you are unable to extract just latitude and longitude from the location object.
