metadata

[missinglink]

optionally print record metadata such as version and timestamp by specifying the --metadata=true flag.

Eg.

{
  "id": 26882421,
  "type": "node",
  "lat": 52.484265400000005,
  "lon": 13.320669100000002,
  "tags": {
    "amenity": "fuel",
    "name": "Aral",
    "wheelchair": "yes"
  },
  "meta": {
    "version": 10,
    "timestamp": 1450987152
  }
}

I was hoping that the version information would be useful for determining the popularity of a record, although I'm not sure about that...

On the fence as to whether to merge this or not, it wouldn't break anything because its disabled by default.

It's a useful feature for sure. While the version number might not be a super strong signal, the timestmap of last edit certainly is, and was brought up back in pelias/pelias#351.
