The IATI Datastore was launched in 2012 although has never progressed beyond alpha status. Whilst this tool experiences some use, it frequently suffers import problems and is difficult to debug and maintain from a technical point of view. Informal usability research has shown that significant improvements are needed to make this tool useful for wider data use, particularly for non-technical users.The IATI Technical Team are committed to providing a more usable, robust and maintainable iteration of the Datastore, with work beginning in mid 2017. In this session we will begin to gather user requirements for a future data store. Outputs will form part of the detailed scoping resulting in technology choices that will lead to an improved product.
