I've just re-read this thread following Bill's email asking us to review the discussion as I'm disappointed this hasn't reached consensus (as it's a big challenge in our work). To summarise:
The IATI Technical Team put forward the original submission (which was based on a consultation with M&E people in a wide variety of organisations):
Add "9 - Qualitative" to the IndicatorMeasure codelist
Make the following value attributes optional
At the consultation call the proposal received no objections.
I may have missed something someone said in the thread, but I think the subsequent comments all agreed with the proposal with the exception of @Herman (sorry to single you out!).
If I've understood correctly, the points of disagreement are views on whether:
1) All results can be translated meaningfully and usefully into a quantitative scale of some kind
2) If they can't, qualitative results should only be communicated through a document link
This may have already happened, but would a call between @Herman and the original proposers of the change, such as @mikesmith be helpful to talk directly about the point of disagreement and see if we can find a way forward?
