factbook.sql World Factbook Country Profiles in SQL (Incl. factbook.db Download)
Hello, I’ve updated the factbook gem, that is, v1.1. What’s news? The script now lets you build an SQL database from the official web pages (country profiles) published by the CIA. To make it easy to get started I’ve added (yet another) new project, that is, /factbook.sql that offers an SQL schema for the World Factbook and includes a pre-built single-file SQLite database, that is, factbook.db for download. Note, using the factbook scripts you can build yourself an up-to-date copy. All code and data public domain. Cheers.
