Just been looking at the World Bank's web site and their approach to Open Data http://maps.worldbank.org/about/opendata
They show maps and allow the download of the raw data as .csv files.
However, on the API page http://api.worldbank.org/projects they do state, "Data on project locations are collected through a desk study of existing project documents and are being released as a test database. Further work is required for data validation and quality enhancements"
The screenshot shows a road project in Nigeria. The data (and more info) is available in the csv download.
