A free open public domain world database & schema for use in any (programming) language (e.g. uses plain text fixtures/data sets).

Use the worlddb command line tool to build yourself a copy of the world.db from the plain text fixtures in two steps.

Step 1: Get a copy of the world.db fixtures

$ git clone git://github.com/openmundi/world.db.git

Step 2: Let's build the world.db

$ worldb setup --include ./world.db

That's it. See the worlddb command line tool project for more.

Try the world.db Web Admin demo running on Heroku worlddb.herokuapp.com.

The world.db includes the following tables:

• countries
• regions
• cities
• tags
• taggings (many-to-many join table for tags+countries/regions/cities)
• langs
• usages (many-to-many join table for langs+countries)
• props
