IATI is a global initiative working to improve the transparency of development and humanitarian resources and their results to address poverty and crises. IATI encourages governments and organisations to publish information about their spending and projects according to IATI's open data standard. The IATI Standard is a set of rules and guidance for publishing useful development and humanitarian data. Once published, this data is free and open for anyone to access online. To-date, over 1000 organisations have published data on the spending of over one million development or humanitarian activities. They include donor governments, multilateral agencies, development finance institutions, foundations, NGOs and private sector organisations. IATI is managed by a Secretariat led by the United Nations Development Programme (UNDP), together with staff from the United Nations Office for Project Services (UNOPS) and Development Initiatives (an international development organisation). The initiative is funded and governed by its members representing governments, and development and humanitarian organisations across the world.
