Please find current discussions relating to IATI at http://discuss.iatistandard.org/

This group is now deprecated, and acts solely as an archive for technical discussions related to the International Aid Transparency Initiative (IATI) data between late 2011, and mid 2015.

From the original description:

The IATI Standard is an XML standard for sharing information on donor organisations, aid budgets, aid activities and aid transactions along with associated information. You can find details documentation of the IATI Standard, and a support tracker/knowledge base for basic queries about using the data, or for reporting problems, at http://www.iatistandard.org.

This is a discussion list and a key communication channel for the Technical Advisory Group. It is used to discuss changes to the standard, issues with IATI data, and to share news and updates relating to IATI tools.

See the IATI Standard Wiki for more details.
(This group was previously named IATI-tools, and was focussed solely on data users).
