On April 20, 2010, the World Bank announced that it would offer free access to its global development and financial indicators. This puts the widely used and well-liked World Development Indicators (WDI), the Global Development Finance (GDF), the African Development Indicators, and the Global Economic Monitor (GEM) at the fingertips of anybody who wants to use them for analysis, policy development, decision-making, etc. (http://data.worldbank.org/). The data have become freely available to anybody who wants to re-distribute them, use them in mash-ups or apps. The World Bank has created a how-to guide and by mid-2010 will make the Web API available to developers. The data catalog offers an extensive listing of all databases and pre-formatted tables. The terms of use of the data are very liberal and impose very few restrictions.
