## 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`:
``` bash
#!/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
import_region world
```
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()
261
```
