Import

Use the mongoimport command/tool to import the factbook.json documents. For example, to import the country profile of Austria (that is, europe/au.json) use:

$ mongoimport --db world --collection factbook --file europe/au.json

To import all documents use a shell script. Example import.sh:

#!/bin/bash

MONGOIMPORT = mongoimport
SOURCE      = .           # assume working folder (as root)

function import_file {
  echo "  importing >${1}<..."
  ${MONGOIMPORT} --db world --collection factbook --file ${1}
}

function import_region {
  for file in ${SOURCE}/$1/*.json
  do
    import_file ${file}
  done
}

import_region africa
import_region antarctica
import_region australia-oceania
import_region central-america-n-caribbean
import_region central-asia
import_region east-n-southeast-asia
import_region europe
import_region middle-east
import_region north-america
import_region oceans
import_region south-america
import_region south-asia

To check up if all country profiles got imported use a query in the mongo shell e.g.:

> use world
  switched to db world
> db.factbook.count()
