It's very encouraging that global development banks continue to find value in making public spending data, open data, in pursuit of improved transparency, combating corruption and better communication with the public. Many have begun their effort with GIS/ maps, e.g. the World Bank (WB) and the African Development Bank (AfDB) - maps tell stories well. Over and above the medium(s) has arisen a principle: 'Open by Default'. The Open Government Partnership (OGP) which works to get governments to commit to openness has the support of the WB, ADB, OECD, IDB and UNDP, and has expressed such a principle. As this excellent summary by the World Bank states: 'Showing where the money goes is becoming the new normal.'
