As an extension to OIPA’s functionality we would like to add the option to convert values to a specific currency. For example, this would make it possible to do aggregations on transaction in different currencies.
To be able to do this we need an exchange rate dataset. Datasets like this are published by IMF, World Bank and OECD and others. However, we are unsure what dataset is best suited for this purpose, seeing how they seem to differ and secondly we do not want to make use general market rates.
Does the IATI community have an opinion on what dataset would be most accurate to use for this use?
Work has been done by ourselves last year, D-Portal and work on the BD AIMS has been done, but no general solution exists that could work for IATI works.
Suggestions more than welcome.
