John, by ECHO I assume you mean EDRIS (European Emergency and Disaster Response Information System). ECHO publish their own activities to IATI.
EU members do not report directly to FTS but are required to key their data into EDRIS.
Data is transferred from EDRIS to FTS (OCHA Financial Tracking Service) every night.
No. We would hope that in future EDRIS will be able to import IATI data.
FTS can import IATI v2.02 data (i.e. the latest version including humanitarian improvements). I'm not sure whether it is doing so yet. @foos @ximboden could you confirm?
