Comprehensive language code information, consisting of ISO 639-1, ISO 639-2 and IETF language types.

Data

Data is taken from the Library of Congress as the ISO 639-2 Registration Authority, and from the Unicode Common Locale Data Repository.

data/language-codes.csv

This file contains the 184 languages with ISO 639-1 (alpha 2 / two letter) codes and their English names.

data/language-codes-3b2.csv

This file contains the 184 languages with both ISO 639-2 (alpha 3 / three letter) bibliographic codes and ISO 639-1 codes, and their English names.

data/language-codes-full.csv

This file is more exhaustive.

It contains all languages with ISO 639-2 (alpha 3 / three letter) codes, the respective ISO 639-1 codes (if present), as well as the English and French name of each language.

There are two versions of the three letter codes: bibliographic and terminologic. Each language has a bibliographic code but only a few languages have terminologic codes. Terminologic codes are chosen to be similar to the corresponding ISO 639-1 two letter codes.

Example from Wikipedia:

[…] the German language (Part 1: de) has two codes in Part 2: ger (T code) and deu (B code), whereas there is only one code in Part 2, eng, for the English language.

There are four special codes: mul, und, mis, zxx; and a reserved range qaa-qtz.

data/ietf-language-tags.csv

This file lists all IETF language tags of the official resource indicated by http://www.iana.org/assignments/language-tag-extensions-registry that into the /main folder of http://www.unicode.org/Public/cldr/latest/core.zip (project cldr.unicode.org).

Preparation

This package includes a bash script to fetch current language code information and adjust the formatting. The file ietf-language-tags.csv is obtained with ietf-lanGen.php.

Import into your tool

If you are using R here's how to get the data you want quickly loaded:

install.packages("jsonlite")
library("jsonlite")

json_file <- "http://datahub.io/core/language-codes/datapackage.json"
json_data <- fromJSON(paste(readLines(json_file), collapse=""))

# access csv file by the index starting from 1
path_to_file = json_data$resources[[1]]$path
data <- read.csv(url(path_to_file))
print(data)

In order to work with Data Packages in Pandas you need to install the Frictionless Data data package library and the pandas extension:

pip install datapackage
pip install jsontableschema-pandas

To get the data run following code:

import datapackage

data_url = "http://datahub.io/core/language-codes/datapackage.json"

# to load Data Package into storage
storage = datapackage.push_datapackage(data_url, 'pandas')

# data frames available (corresponding to data files in original dataset)
storage.buckets

# you can access datasets inside storage, e.g. the first one:
storage[storage.buckets[0]]

For Python, first install the `datapackage` library (all the datasets on DataHub are Data Packages):

pip install datapackage

To get Data Package into your Python environment, run following code:

from datapackage import Package

package = Package('http://datahub.io/core/language-codes/datapackage.json')

# get list of resources:
resources = package.descriptor['resources']
resourceList = [resources[x]['name'] for x in range(0, len(resources))]
print(resourceList)

data = package.resources[0].read()
print(data)

If you are using JavaScript, please, follow instructions below:

Install data.js module using npm:

  $ npm install data.js

Once the package is installed, use the following code snippet:

const {Dataset} = require('data.js')

const path = 'http://datahub.io/core/language-codes/datapackage.json'

// We're using self-invoking function here as we want to use async-await syntax:
(async () => {
  const dataset = await Dataset.load(path)

  // Get the first data file in this dataset
  const file = dataset.resources[0]
  // Get a raw stream
  const stream = await file.stream()
  // entire file as a buffer (be careful with large files!)
  const buffer = await file.buffer
})()

Install the datapackage library created specially for Ruby language using gem:

gem install datapackage

Now get the dataset and read the data:

require 'datapackage'

path = 'http://datahub.io/core/language-codes/datapackage.json'

package = DataPackage::Package.new(path)
# So package variable contains metadata. You can see it:
puts package

# Read data itself:
resource = package.resources[0]
data = resource.read
puts data
Datapackage.json
