The World, also known as World Index, will be an online compendium of the nations of the world. It will host comprehensive data on the world's recognised countries, including prose-style entries on various aspects of the country. Over time, regions, settlements, and geographical features of each country will have their own entries.
Think of it as a more concise Wikipedia with the writing style of TVTropes.
An idea of the sections of prose-style entries: overview, geography, population, history, politics, culture, economy.
